Finding a Supervisor
Choosing a supervisor is one of the most important decisions you'll make in graduate school. They'll be your mentor and adviser, and you'll work together closely throughout your graduate career.
Researching Potential Supervisors
You should select a supervisor with a strong record of research and publication in your area of interest. When looking into potential supervisors for your program, become familiar with the type of research they do and their working style.
- Read journals or conference papers, and sit in on any presentations.
- Look at their web site and read their CV. Their publications should give you a sense of the type of research you'd be doing.
- Talk to their students to get a sense of how you'd fit together.
Finding the Perfect Fit
Contact each of your potential supervisors to discuss your research interests, and see if they would be interested and available. Be sure to ask them about their availability during your graduate program, and whether they're planning any extended absences during that time. When considering potential supervisors you should talk to several professors before asking one to become your supervisor. Be sure you understand what your prospective supervisor would expect of you as a graduate student.
Current Available Graduate Projects
Below is a list of current opportunities for prospective students interested in joining the department, however this list is not exhaustive. Please feel free to contact individual faculty members regarding other opportunities involving shared research interests.
Students are sought (M.Sc. and Ph.D.) for a variety of studies on meteorites and analogue materials to investigate formation, shock and cosmic ray irradiation processes. Graduate projects are available with several researchers in the Department. Some example projects include:
- Extended investigation of newly discovered meteorites.
- Investigation of the bulk properties and mineralogy of the Tagish Lake carbonaceous chondrite: a) as an analogue for primitive bodies in the Solar System; and, b) as a mechanically friable material which survived dynamical evolution and atmospheric entry (Dr. Peter Brown).
- Calibration of shock metamorphism in meteorites as observed by optical petrography, micro X-ray diffraction and other techniques, using experimentally shocked materials (Dr. Roberta Flemming)
A two-year M.Sc. position is available immediately in the Department of Earth Sciences at the University of Western Ontario, to conduct graduate research in a subproject of a high-resolution stratigraphic study of the Middle Devonian Hamilton Group in southern Ontario, Canada.
Components of the project include aspects of paleoecology, taphonomy, biostratigraphy, diagenesis, and sedimentology. The project as a whole will involve high-resolution correlation of strata of the Appalachian foreland basin into intracratonic Michigan basin, with the ultimate aim of elucidating the depositional history of this bridging area.
The specific project the M.Sc. candidate will undertake, and the subdiscipline(s) focused on in his/her project will be tailored to the strengths and interests of the individual. Preference will be given to enthusiastic applicants with a strong interest in interdisciplinary geological research, superior academic credentials and strong communication skills. Interested applicants are urged to contact Cam Tsujita.
The GEOMETRIC Lab led by Dr. Audrey Bouvier is seeking highly motivated graduate students to work on geochemical and geochronological studies of meteorites or terrestrial rocks. Several projects are available depending on the student’s research interests. Students will work in Dr. Bouvier’s newly-established clean chemistry laboratory for trace metal isotope studies and with other researchers at Western and internationally for specific aspects of the project.
Support is now available for two M.Sc. positions shared between the Department of Earth Sciences and Surface Science Western, UWO. The candidates will investigate factors controlling the separation of mineral phases in a flotation scheme with specific reference to surface chemistry.
One candidate will be involved with: the identification of secondary ion yields in common sulphide minerals with the goal to partially determine fundamental parameters controlling variability; the creation of relative sensitivity factors (RSFs) for the primary matrix elements in the most common sulphide minerals; to create semi-quantitative calibration indices for surface modifiers and to incorporate the RSF and calibration indices into the existing surface chemical analyses technique by ToF-SIMS; to test the novel technology and its effectiveness as a predictive tool.
The second position will be related to: the activator/collector facilitated inadvertent flotation of non-value gangue silicates in problematic ores. The specific system we will address involves the flotation separation of Ni-bearing pentlandite from pyroxene which, within the Sudbury ores, occurs in two crystallographic (orthrombic versus monoclinic) species. The student will perform a number of experiments on both monoclinic and orthrombic pyroxenes by ToF-SIMS and XPS to determine the fundamental controls that promote favourable conditions for surface chemical modification and inadvertent flotation.
The successful candidate will gain experience in mineral separation technology, and a variety of surface analytical techniques including ToF-SIMS, XPS and SEM/EDX. The candidate will also work closely with and benefit from the interaction with mineralogists and metallurgists from one of the world's leaders in developmental strategies for mineral recovery.
Interested students should contact Dr. Brian Hart
Dr. Robert Linnen has opportunities for M.Sc. and Ph.D. students in three areas, two of which will involve collaborations with mineral exploration companies. For further information please contact Dr. Robert Linnen.
- Lithium pegmatites: Li pegmatites are currently a source for the batteries used in electric cars. Projects will involve geological mapping to establish the structural controls of pegmatite emplacement and evaluating lithogeochemistry and mineral chemistry as mineral exploration tools.
- Intrusion-related gold: Detailed studies of alteration and mineralization of Archean intrusion-related deposits. Studies may also apply stable isotopes, age dating and structural analysis to understanding this deposit type.
- Experimental Petrology: Experimental studies of the behavior of rare-metals and precious metals in magmatic-hydrothermal systems.
Dr. Roberta Flemming at the Department of Earth Sciences at University of Western Ontario has openings for M.Sc. or Ph.D. candidates interested in pursuing fundamental or applied studies of minerals in the following areas:
- Fundamental understanding and quantification of mineral behavior as a function of pressure (P), temperature (T) and composition (X). Projects involve mineral synthesis (at controlled P-T), and determination of crystal structure (by X-ray diffraction/Rietveld refinement), crystal chemistry (by EPMA), and cation order-disorder (by Nuclear Magnetic Resonance (NMR) spectroscopy (e.g. 29 Si NMR provides a measure of Si/Al order in aluminosilicates). These data have application in geothermobarometry.
- Systematic investigation of Kimberlite Indicator Minerals (KIM) (e.g. chromite, Cr-diopside). Variation in unit cell parameters (measured by µXRD) is correlated to geochemical data (by EPMA), on a grain-by-grain basis, with the aim of developing µXRD as a tool for diamond exploration. Inclusions and strain, observed by µXRD, give additional clues to origin.
- Systematic mineralogical investigation of meteorites. In situ µXRD provides rapid mineral ID for meteorite classification, as well as unit cell parameters for addition to our growing database of unit cell parameters for meteorite minerals. Unit cell parameters can be correlated to geochemical information, and in some cases (e.g. clinopyroxene and olivine in basaltic meteorites) this may be correlated to planetary origin. Rietveld refinement of powder XRD data provides modal mineral analysis of bulk sample, and enables crystal structural study of selected phases.
- Development of micro X-ray diffraction (µXRD) as a tool for geologists. Micro XRD provides a unique opportunity to correlate crystal structural information with other microanalytical data on the microscopic scale (50-500 µm) not previously available routinely. Furthermore, minerals can be examined in situ, preserving orientational information. Projects include:
- Quantification of strain-related mosaicity in minerals in meteorites, impact structures, and other rocks, with an aim toward development of a µXRD strain index and calibration using existing strain indices.
- Development of µXRD for exsolution geothermometry. (e.g. two pyroxenes). GADDS image provides simultaneous unit cell information for both phases, as well as their T-dependent orientational relationship.
Facilities at UWO include a Bruker D8 Discover micro X-ray diffractometer, High-T and High-P laboratories, EPMA, SEM, FTIR, Raman, and XRF facilities (Earth Sciences), 400 and 600 MHz solid-state NMRs (Chemistry), XPS and SIMS facilities (Surface Science Western).
If you wish to obtain more information about these projects, or other possible projects, please contact Dr. Roberta Flemming. Collaborative projects with other faculty are also possible. Research and teaching assistantships are guaranteed for all qualified students.

Supervisor: Fred J. Longstaffe
The cause of megafaunal extinction (climate change, human hunting, etc.) in North America continues to be a topic of vigorous debate. Bone and teeth from Late Pleistocene megafauna will be used to determine ecological, environmental and climatic change in southern Ontario through oxygen, carbon and nitrogen isotopic analysis of bioapatite and associated collagen (including amino acids). This project is part of our CFI-CRC funded 'Back to the Future Climate-Change in the Americas’ initiative.
1 M.Sc. and 1 Ph.D. candidates are required. Some fieldwork is necessary. Analytical work is based in the Laboratory for Stable Isotope Science: http://www.uwo.ca/earth/LSIS/index.htm.
Project Title: Stable isotope studies of Late Pleistocene and Holocene climate shifting in the Lake Erie basin.
Supervisor: Fred J. Longstaffe
The cause(s) of the Younger Dryas and the nature of subsequent Holocene climate warming remain hotly debated, as do their consequences for the Great Lakes basin. As part of a comprehensive study of all Great Lakes, we will use isotopic proxies (ostracodes, clams, organic matter) and organic biomarkers (e.g., n-alkanes) in three sediment cores from Lake Erie to identify periods of glacial meltwater flow and shifts in lakewater productivity over the last ~15,000 cal years BP in southwestern Ontario. This project is part of our CFI-CRC funded 'Back to the Future Climate-Change in the Americas’ initiative.
1 M.Sc. and 1 Ph.D. candidates are required. Some fieldwork is required. Analytical work is based in the Laboratory for Stable Isotope Science: http://www.uwo.ca/earth/LSIS/index.htm.Project Title: Stable isotope investigations of climate change in Southern Ontario since ~7,000 cal years BP
Supervisor: Fred J. Longstaffe
Late Pleistocene and Holocene sediments of the Great Lakes Basin contain many isotopic and organic biomarker proxies for climate change in this region over the last ~15,000 cal years BP. As a companion to ongoing investigations Lakes Superior, Michigan, Huron, Ontario and Erie, we will examine such proxies for climate change contained in sediments from a small sinkhole lake (Barry Lake) located near Peterborough, Ontario, and a small pond (Carolinian Pond) contained in Pinery Provincial Park, Lake Huron, Ontario. The focus is on sediments recording climate changes spanning the warming period called the ‘Holocene Hypsithermal’, later cooling called the ‘Holocene Neoglacial interval’, and climate patterns over the last 500 years, including induced warming over the last ~100 years. This project is part of our CFI-CRC funded 'Back to the Future Climate-Change in the Americas ' initiative.
2 M.Sc. and 1 Ph.D. students are required. Fieldwork is required. Analytical work is based in the Laboratory for Stable Isotope Science: http://www.uwo.ca/earth/LSIS/index.htm.Project Title: Nitrogen-15 dynamics of the Pleistocene Mammoth Steppe
Supervisor: Fred J. Longstaffe
A curious biochemical signature of some Pleistocene megafauna (e.g., mammoths, horses) is their tendency to be enriched in nitrogen-15 relative to other herbivores, except during the latest Pleistocene when a sharp decrease in nitrogen-15 content is commonly observed. Hypotheses to explain these patterns include climate-related dynamics in the ‘Mammoth Steppe’ ecosystem and physiological behaviours affecting nitrogen recycling within the bodies of these large animals. Building on ongoing PhD investigations, we will use carbon and nitrogen isotopic analysis of amino acids in plants and animals to test for changes nitrogen cycling that affected herbivore diet at the base of the foodweb. This project is part of our CFI-CRC funded 'Back to the Future Climate-Change in the Americas ' initiative.
1 M.Sc. and 1 Ph.D. candidates are required. Some fieldwork is required. Experimental plant growth will be based in the Biotron (part of our ‘Growing Beringia’ project. Analytical work is based in the Laboratory for Stable Isotope Science: http://www.uwo.ca/earth/LSIS/index.htm.
Project Title: Stable isotopic investigations of cellulose from Carolinian forests and related ecosystems in the southern Great Lakes basin.
Research opportunities are available at the M.Sc. or Ph.D. level to investigate variations in the hydrogen, oxygen and carbon isotopic compositions of cellulose from a type locality (Pinery Provincial Park) in southwestern Ontario. This area contains a diverse range of ecosystems, and offers the opportunity to calibrate this potential paleoclimate proxy, and to correlate observed variations in isotopic composition with the climatic history of the area, as determined from historical records and other stable isotope proxies.
