Dr. M. Altaf Arain‘s research program focuses on hydrometeorology, climatology, evapotranspiration, forest and agricultural carbon and water cycles and ecosystem, watershed and global climate models. He has established a multidisciplinary ecosystem restoration and environmental sustainability research program that explores the interactions and feedbacks between biogeochemical and hydrologic cycles in different-age and -species forest ecosystems and agricultural crops. As part of this program, he has established Turkey Point Environmental Observatory, comprising five flux tower stations near Lake Erie in Southern Ontario, which are part of Global Water Futures (GWF), Ameriflux, global Fluxnet and US-Canada Global Centre programs. Using ground based (eddy covariance, soil CO2 efflux, sapflow systems) and airborne (e.g. drone and satellite remote sensing) his group is exploring carbon sequestration capabilities, water use and sensitivity and resilience of plantation or managed forests and crops to future climate change and extreme weather events. His Lab is also involved in the development of the Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC) used in the Canadian Earth System Model (CanESM) for climate predictions and integrated biogeochemical and hydrologic modelling systems (MESH-CLASSIC) for catchment-scale water cycle studies.

Dr. Janok Bhattacharya‘s research program is mostly focused on investigating the sequence stratigraphy and 3D facies architecture of shelf, shallow marine, paralic, and fluvial depositional systems. Although much industry exploration effort is currently focused on deepwater depositional systems, about 50% of global oil production is currently from shallow marine, paralic and fluvial strata. Despite the continued importance of these reservoir types, ours is one of the only research programs devoted to this important area.

I am also investigating the interrelationships between structure and stratigraphy as a paired process. Specific projects are aimed at examining the effects of meso-scale tectonic structure on high-frequency sequence stratigraphic architecture in foreland basins and the relationship between sedimentation processes and formation of growth faults associated with deltaic depositional systems.

My research program is founded on the fundamentals of sedimentology, fieldwork, facies analysis, and sequence stratigraphy. Our program also crosses the boundaries between geophysics and engineering disciplines and provides an important environment for teamwork and integration that we believe provides a model for industry.

Hello!

I am a radical and feminist geographer and disability studies scholar with interests in housing issues, the marginalization of diverse people in and beyond the academy, state restructuring, law, and disability in the global South and North. I am also interested in ableism as a regime of power in global capitalism—something inspired by a lengthy struggle for accommodation of my needs as a professor disabled by multiple illnesses. I also reflected the realization as well that many other disabled people were in far more disadvantaged circumstances than their academic counterparts. It was time for us to shed more light on this.

I recently retired but remain active in research and writing, serving on graduate supervisory and examining committees, and reviewing articles for journals. I will consider other options—feel free to ask.

My new book Re-Mapping an Ableist World will be published soon by University of Toronto Press, If you share my interests or are curious to find out more I hope you’ll read it!

Dr. Alan Dickin research objective is to reconstruct the geological evolution of the Grenville Province of the Canadian Shield. The Grenville has been the most poorly understood province of the Shield, but Nd isotope mapping (Dickin, 2000) has now identified the major crustal terranes that make up the province. My current research involves detailed mapping of individual terrane boundaries in order to understand their geological history, and thereby reconstruct the accretionary growth of the Shield.

My research areas are on ground, airborne, and satellite remote sensing of vegetation from the leaf to the globe with special focus on:

1. plant structural and photosynthetic traits;
2. land surface and carbon uptake phenology;
3. terrestrial ecosystem primary productivity and greenness;
4. global change impact on terrestrial ecosystem productivity; and
5. terrestrial carbon cycle modelling.

I have done, and am doing, remote sensing of vegetation studies at ecological monitoring sites (e.g., eddy covariance tower networks); on improved product development at regional scale (e.g., leaf area index, primary productivity and land surface phenology); and on global change impact assessment on terrestrial ecosystem productivity at regional (e.g., circumpolar land surface phenology and atmospheric CO2 seasonality) and global scales. Besides remote sensing data, I use ground measurements of plant biophysical variables, photosynthetic traits, atmospheric CO2 concentration, eddy covariance CO2 fluxes and plant phenology; gridded climate data records; terrestrial ecosystem carbon cycle models; and Earth System Model (ESM) outputs.

I retired in 2019 but remain active in research and writing.

I am interested in how the built environment has reflected and shaped our lives, with particular reference to dwellings and residential environments. The influence of the built environment often becomes apparent, and also changes, over long periods of time, and I have found it fruitful to undertake historical research as well as studies of the present. (I am an Associate of the Department of History at McMaster.) Dwellings frame much of our daily life and offer a valuable prism through which to study social, cultural, and economic change.

I have used, and am using, housing as a prism in two contexts:

1. The history of housing, neighbourhoods and suburbs in North America in the twentieth century. By studying the linkages between production and consumption of these environments it is possible to ground, and extend, recent debates about the cultural construction of the economy, and about class and gender differences in the meaning of consumption. The most recent work coming out of this research is What’s in a Name? Talking about Urban Peripheries (edited with Charlotte Vorms) (Toronto, 2017). A companion volume, The Urban Land Market (coedited with Ute Lehrer) will be published in 2018. My book projects at present are a survey of How Cities Matter, and A History of Canadian Urban Neighbourhoods since the 1880s.
2. The current housing scene in Hamilton, Ontario, paying particular attention to the character of the rental stock. Students have interviewed landlords and tenants, and are undertaking an analysis of the growth of condominiums and of patterns of ownership of the rental housing stock. Projected research will examine social and affordable housing. The results of these studies are being interpreted in the context of an analysis of the changing social geography of hamilton since 1970. This research is being undertaken in association with the Neighbourhood Change Research Project, directed by David Hulchanski at the University of Toronto. This project is examining neighbourhood change in seven Canadian cities.

Since obtaining my Ph. D. degree from Clark University in the United States in 1974, my professional career has been sustained by my belief that mathematics and statistics are useful for achieving insights into real-world problems. This is reflected in the title of my dissertation (An Application of Simultaneous Linear Difference and Differential Equations to the Analysis of Interregional Population Dynamics) and in the use of various multivariate statistical models in my research.

I consider myself to be a Population Geographer and a Demographer. The substantive scope of my research and teaching covers mainly internal and international migration processes and partly death and birth processes. The geographical areas of my research interests span more than half a dozen countries, with Canada, the United States, and Japan being the main ones.

After becoming a Professor Emeritus in 2010, I have not only continued migration research but also broadened my research into medical and soil sciences. In the new fields, I have participated in pre-existing research teams, in which the high-quality data gave me the opportunities to continue developing my statistical skills for achieving greater insights into real-world problems (e.g. mortality risks of ICU patients and emissions of CO2 from soil).

Dr. Gita Ljubicic is a Geographer with training in the natural and social sciences, who works primarily at the intersection of cultural and environmental geography. Her work is driven by a deep commitment to respecting and learning from Indigenous knowledge alongside science in order to address complex socio-ecological issues. She and her research team are dedicated to a cooperative, community-driven approach to research that involves developing and fostering working relationships with Indigenous experts and organizations throughout all stages of the research process. Gita has primarily worked with Inuit community members and organizations in Nunavut, but through collaborations she have been involved in research with Inuit, M?©tis, and First Nations communities across the Yukon, Northwest Territories, Nunavut, Nunavik (northern Qu?©bec), and Nunatsiavut (northern Labrador).

Gita has worked with Inuit communities and academic partners to learn from Inuit knowledge about sea ice, caribou, plants, and water in relation to implications of climate change, importance in northern livelihoods and wellbeing, and contributions to decision-making from local to national scales. In all projects the research process itself is an important focus, where she and her team explore: i) collaborative approaches to research; ii) ethics of informed consent in a cross-cultural context; iii) participatory mapping and knowledge representations; and, v) qualitative data management practices. Taken together, the outcomes of learning from Indigenous knowledge, and working together effectively, contribute to efforts to bring together diverse perspectives and evidence for more representative decision-making. Gita and her research team have been engaged in various environmental monitoring, co-management, eduction, and cultural heritage initiatives as an important means of mobilizing research results.

Dr. Bruce Newbold is a Professor in the School of Earth, Environment & Society (SEES) at McMaster University in Hamilton, Ontario. He received his PhD in Geography from McMaster University in 1994, and worked at the University of Illinois Urbana-Champaign between 1994 and 2000 before returning to McMaster in 2000. Since returning to McMaster, he has held Guest Scholar positions at the Center for Comparative Immigration Studies, University of California San Diego (2004), and the Medical Research Council’s Social and Public Health Sciences Unit at the University of Glasgow (2008), a position which included a Fellowship through the Department of Urban Studies, University of Glasgow. His research interests focus on population issues as they relate to immigration, migration, health, and aging. Recent research has focused on the role of migration in the development and transfer of human capital and income across space, commuting and sustainability questions, the income benefits associated with migration, immigrant health, and immigrant settlement processes.

Current Research:

As of the 2021 census, 19% of Canada’s population was aged 65 and over, with this share projected to increase to approximately 23% by 2043 as Canada’s population continues to age rapidly and fertility rates remain low.. While many of older adults will expect or desire to age in place, many will move to ‘downsize’ their living space, move to be closer to family for support, or move into care facilities. As more Canadians age into retirement, there will be more migrants and understanding where they choose to live/move is vital. Despite significant attention to migration flows within the labour force, there has been much less attention given to migration within Canada’s older adult population. From a theoretical perspective, there has also been little advancement in our understanding of the motivations associated with moves by older adults, hampering our ability to plan for Canada’s aging population, including with respect to housing options, transportation, and service provision.

This SSHRC funded research project will seek to understand the patterns, motivations, and timing for moves among older adults. In addition to understanding the spatial patterns associated with moves, the proposed research will systematically identify the most important predictors of moves, while also providing a tool to predict whether an individual will/will not move, enabling planning for Canada’s aging population.

He currently serves as Editor-in-Chief of the Journal of Geographical Systems, and sits on the editorial boards of Transportation, Journal of Transport Geography, Geographical Analysis, and International Journal of Geographical Information Science, among others.

Yorgos Papageorgiou received his diploma in architecture from the National Technical University of Athens in 1959, his M.C.P. in 1967 and his Ph.D. in 1970, both from the Ohio State University. Between 1963 and 1965 he also attended the Graduate School of Ekistics in Athens. During his studies and throughout his subsequent academic career he has been mainly preoccupied with the spatial organisation of human activity. But the path he took from architecture, to urban design and planning, to economic geography, marks a gradual shift from the small scale to the large and from the applied to the theoretical.

Between 1965 and 1972 he was actively involved with the Architecture and Ekistics Group of Athens. He joined the department of geography at McMaster University in 1970. From 1989 he held a joint appointment with the department of economics. He retired in 2001. For about fifteen years and until 2005 he devoted some of his time to Thirty Bench Wines in the Niagara peninsula as a co-owner and winemaker.

He has visited several universities and institutes during his academic career, including the National Research Foundation of Athens, the Institute of Geography and Spatial Organisation of the Polish Academy of Sciences, the University of California at Santa Barbara, the Universite Catholique de Louvain, the Committee for Systems Analysis of the USSR Academy of Sciences, Erasmus University, the Universite de Bourgogne, the Instituto Ricerche Economico-Sociali del Piemonte, Tilburg University, the National Technical University of Athens, the Politechnico di Torino and Tel-Aviv University. Recognitions for his work include two honorary doctorates (from the Universite Catholique de Louvain and the University of the Aegean) and the induction as a Fellow of the Regional Science Association International.

He has had the good fortune of working with excellent people for many years, and the benefit from these collaborations is clearly reflected throughout his academic work. He generalised the negative exponential density function from a monocentric to a polycentric framework (see G1-3 in Selected Publications) and provided a theoretical rationale for both in E5 and C2 respectively. He pioneered the field on agglomeration (see R3,4, E1,2,12 and C1) and proposed an explanation for the globally observed catastrophic growth of large cities in G7. He developed innovative ways of dealing with the impact of uncertainty and heterogeneity in tastes on urban equilibrium structure and location theory (see E3, R6-8 and G18). He contributed to the study of regional population dynamics by combining evolutionary migration models (mainly drawn from physics) with stochastic utility theory in G12,13. He applied this method to the Canadian regional population system and studied its disequilibrium dynamics in G19,20. Using the theory of extreme-value statistics, he developed in G17 a method that derives from first principles various discrete-choice models either in discrete or in continuous space, including the multinomial logit. He developed models for the analysis of policy issues at the urban, regional and international level (see E7,11 and R11-13). Finally, he has struggled with some fundamental problems (see R5,9, G15 and E6,8). He currently works primarily on urban origins (see, for example, C1) and on imperfect public choice.

The price he paid for working across disciplines is that he had to settle on a margin, never quite accepted by those in another discipline, nor quite rejected by those in his own discipline.

Dr. Elli Papangelakis is an Assistant Professor in the School of Earth, Environment & Society at McMaster University. She has a multidisciplinary education background, with a BSc in Physics and Geography (University of Toronto), a MSc in Geography (UBC), and a PhD in Civil and Environmental Engineering (University of Waterloo). Her research focuses on the effects of urbanization and land-use change on the geomorphic processes of rivers through a combination of fieldwork, laboratory, and GIS research methods. Her primary goal is to better understand sediment transport processes, morphologic adjustments, and physical habitat characteristics of urban rivers. She is particularly interested in urban river restoration and management, specifically on assessing the performance of different restoration designs and in the development of novel river management strategies that bring together the most advanced science and technology from different fields. Most of her research focuses is confused in Southern Ontario, which provides an excellent example of heavily-urbanized and managed fluvial environments. She also works with salmon habitat restoration projects in British Columbia.

Examples of exciting new approaches her research group employs:

• Gravel augmentation to rehabilitate urban rivers
• Measuring geomorphic parameters using UAV (drone) based imaging
• GIS-based erosion sensitivity models
• Citizen science for geomorphic monitoring

My research primarily focuses on the structural, tectonic and magmatic evolution of continental margins, including the adjacent onshore areas and offshore sedimentary basins. I am particularly interested in rifting and breakup, rift-related magmatism, structural inheritance and mantle dynamics.

Geographically, my work to date has focused on the continental margins of the North Atlantic and surrounding regions including: Newfoundland, Greenland, Jan Mayen, Labrador and the UK/Irish margin. The nature of my work requires a multifaceted approach incorporating a wide variety of approaches and methodologies such as: seismic interpretation, field-based studies, numerical modelling, petrology, structural modelling and geochemistry.

Dr. Peace is the faculty lead for the D. Keith MacDonald Earth Sciences Structural Geology Advancement Fund. This fund, generously gifted by alumnus Keith MacDonald ’80, P.

Léa Ravensbergen focuses on critical transport research and explores how cities can foster more sustainable transport systems in an equitable manner. She uses a combination of qualitative (interviews, mobile ethnography, participatory mapping, observations) and quantitative (survey analysis, GIS) methods to uncover barriers to walking, cycling, and public transport. Much of her recent work has focused on gender-equity in active travel and age-friendly transport planning.

Dr. Eduard G. Reinhardt is a micropaleontologist studying how groundwater condition changed over climate cycles using cave sediments. His recent research in the Yucatan of Mexico focusses on reconstructing the potability of groundwater through drought cycles during the late Holocene. This has implications for the decline of Maya civilizations but also for future groundwater management in the coastal zone.

Dr. Jack Rink came to McMaster University in 1992 after completing his Ph.D. at Florida State University and an NSF-NATO Postdoctoral Fellowship at the University of Cambridge, where he began his career in geochronology. Dr. Rink has won teaching awards and a research excellence award in his time at McMaster. His early work in concert with archaeologists and palaeontologists focused on the dating Palaeolithic sites in the Middle East, Europe, China and Indonesia. His more famous exploits include dating of Homo floresiensis (the hobbit) and Gigantopithecus blackii fossils (the latter being considered by some to be relevant to the Bigfoot/Yeti hypothesis). His more recent work involves dating coastal landforms of Holocene and Pleistocene age, and magnetic navigation by sea turtles. He has organized more than 30 international scientific expeditions. Beyond utilizing dating techniques, he has participated in the development of a dating technique for pushing the time range of quartz-sand dating methods for coastal processes into the Pliocene.

Dr. Jack Rink research interests involve luminescence emission and magnetic resonance properties of minerals and biominerals, which are applied to problems in geochronology of the young earth, especially young coastal systems. He mainly uses electron spin resonance dating and luminescence dating as tools in this work, but is also involved in developing better dating methodologies to solve current problems in these areas. His newest area of interest is the use of luminescence properties of minerals to study sand transport in coastal systems, which spans the fields of coastal engineering, landscape evolution, storm recurrence frequency and shipwreck preservation issues in underwater archaeological sites.

CURRENT RESEARH PROJECTS

Studies of Bone

Our area of research is the investigation of the fundamental properties of bone from many aspects. Bone is the material that bones are made of. It is a natural composite material in which a strong, brittle crystalline material is woven together with a soft, weak material to produce a composite that is strong and resilient. The strong component is a form of the geological mineral apatite, a calcium phosphate, while the soft material is collagen in the form of fibers about 50 nanometers in diameter. Our work focuses on the mineral component and how it is assembled into this marvelous composite. We are working on a number of specific project to investigate this.

Ultrastructure of bone

The crystals of apatite in bone are only 5 nanometers (nm) thick and about 30 to 50 nm wide. Therefore they have to be viewed using a transmission electron microscope (TEM). Working at the Canadian Centre for Electron Microscopy (CCEM), we have been studying the details of how these crystals are assembled into bone. Here is a typical image showing how the crystals (dark)

Wrap around the fibrils of collagen (light). The scale bar is 200 nm long. We have seen these structures in bones from every kind of vertebrate (fish, reptiles, mammals) and also similar structures are found in the dentin of teeth. We are are trying to learn how these structures form by using imaging methods developed by materials engineers, including ion milling, focused ion beam (FIB) milling, and various TEM methods: bright field, dark field, HAADF, and electron diffraction. The work is being done in collaboration with Gianluigi Botton (director, CCEM) and Prof. Kathryn Grandfield (Dept of Materials Science and Engineering) along with various undergrad and graduate students (Lucy Luo, Dakota Binkley, Ivan Strakhov).

Particular projects under way include the following:

1. Ultrastructural studies of intertubular dentin in human and other teeth, relation to bone structure (Lucy Luo)

2. Electron energy loss spectroscopy (EELS) of cross sections of bone to localize collagen and other proteins (Lucy Luo, Carmen Andrei, K. Grandfield)

3. Ultrastructural studies of osteoporotic bone to test for nanometer-scale changes in bone structure (I Strakhov M.Sc project, K. Grandfield and HPS; funded by MccMaster Institute for Research in Aging [MIRA])

4. HAADF analysis of FIB sections of bone to identify larger-scale features (V. Vuong, M.Sc, K. Grandfield, H Schwarcz)

Mechanical modeling of bone

Using the model of bone ultrastructure which we have developed (McNally et al ., 2012) a group at the University of Illinois, Urbana-Champaign has been calculating the mechanical behavior of bone under stress. This work is under the direction of Prof. Iwona Jasiuk, Dept. of Mechanical Engineering, UIUC. Their computations suggested that the new model provides a closer fit to the observed properties of bone. The work is in collaboration with students Diab Abueidda and Fereshteh Sabet. Future studies will include using atomic force microscopy to measure the mechanical characteristics of single apatite platelets (“mineral lamellae”) extracted from bone.

Chemical composition of osteons and bone

With advancing age, mammalian bone is gradually replaced by new bone material (remodeling) in the form of cylindrical structures about 150 micrometers (μm) in diameter, called osteons. It is believed that the composition of the bone in these replacement structures differs from that in the replaced primary bone. We are studying this phenomenon, and other related issues, using the electron microprobe (EMP). This device allows us to determine the complete chemical composition of bone at multiple μm-sized spots and track changes in composition across volumes of bone that have grown at different times. The analyses of Ca and P also allow us to learn about variations in the nature of the apatite mineral that is present in bone. This work is being done at Western University in collaboration with Marc Beauchamp, and with McMaster personnel Dakota Binkley (M.Sc candidate), Kathryn Grandfield and HPS.

My research focuses on understanding the fate and transport of organic compounds, organic contaminants in particular, in the environment and on the microbial processes which control carbon cycling in both contaminated and natural environments. Research in my lab uses both traditional and novel techniques to investigate questions relating to topics ranging from organic contaminant sources and biodegradation in the environment to the metabolic processes and bio-signatures associated with microbial metabolism and carbon cycling in extreme environments. The common theme in this research is to understand the fundamental processes that control the environment around us and the impact that life, including industrial society, has on the environment and vice versa.

My primary research interests are in Subsurface Contaminant Hydrology. That includes Contaminant Fate and Transport within the subdisciplines of Hydrogeology (below the water table) and Vadose Zone Hydrology (above the water table). I am particularly interested in the study of multiphase flow and unsaturated flow in porous media, i.e. when more than one fluid is present. My research approach emphasises highly controlled laboratory based experiments to investigate primary mechanisms and processes controlling fluid flow and contaminant transport. In addition, numerical modelling is used to analyse laboratory and field data, design further experiments, and investigate the potential implications of the research results.

This research improves and extends our fundamental understanding of Subsurface Contaminant Hydrology and the technologies used in Groundwater and Soil Contamination Investigations, Monitoring, Simulation, and Remediation.

Dr. James Michael Waddington’s research in ecohydrology studies the ecological and hydrological processes that underlie the structure and function of wetlands and watershed ecosystems and the distribution, movement, and quality of water.

With his research foundation firmly in hydrology and by adopting a watershed ecosystems framework, he uses innovative field experimental manipulations and ecohydrological modelling to understand watershed interactions of water, vegetation, soil and greenhouse gas exchange. His research examines the effects of wildfire, drought and resource extraction on watershed ecohydrology with a focus on ecosystems, such as peatlands, that may be sensitive to changes in hydrology. He is developing new wetland restoration approaches and designs for resource managers, fire managers and industry partners to enhance watershed resilience to climate change.

Dr. Robert Wilton earned a Hons. B.A. at the University of Hull (UK) and a M.A. and Ph.D. from the University of Southern California in Los Angeles. His research is broadly concerned with the social geographies of exclusion. He is interested in (1) the ways that some groups within society are excluded from valued environments, (2) the ways in which this exclusion reproduces the marginal or problem status of such groups, and (3) the capacity of such groups to contest their exclusion. Much of his research has focused specifically on the experiences of people with disabilities. His doctoral work, for example, examined the origins of community opposition to housing for disabled persons. More recently, his work has focused on three topics. He is completing SSHRC-funded research on the exclusion of disabled persons from spaces of paid employment, and the strategies used by individuals to overcome this exclusion. He is working with a coalition of people living with mental illness to document the negative impacts of poverty and poor housing on quality of life and social participation.

Dr. Ming-ko (Hok) Woo studied Geography and Geology at the University of Hong Kong, and obtained his doctoral degree from the University of British Columbia. He is a Professional Hydrologist of the American Institute of Hydrology, a Fellow of the Arctic Institute of North America; and a Fellow of the Royal Canadian Geographical Society. Dr. Woo has conducted field investigations in the far North for four decades, working in a range of environments, from the polar desert of the High Arctic, subapline woodlands in the subarctic, to the extensive wetlands of Hudson Bay Lowlands. He has also studied drought problems in the semi-arid Sahel of northern Nigeria and the Canadian Prairies, soil erosion in subtropical south China, climate variability and hydrology of large-basins in northwestern Canada. He was recognized with the Award for Scholarly Distinction from the Canadian Association of Geographers and with the prestigious Tuzo Wilson Medal from the Canadian Geophysical Union; the latter organization also has established in his honour the Woo Lectures in Hydrology, delivered annually by invited speakers. He was conferred an honorary degree of Doctor of Environmental Studies from the University of Waterloo for his outstanding and pioneering work in the fields of cold-regions hydrology, wetland ecosystems, and hydrological modelling. He takes pride in his former students and research associates who have successfully trained and mentored generations of practitioners and instructors in the fields of Hydrology and Environmental Science.
