Bill Lebarge

Placer Geologist

My name is Bill LeBarge. I was born and raised in the Yukon and I am a beneficiary of the Ta'an Kwatch'an First Nation - the people of Lake Laberge. I am the Placer Geologist for the Yukon Geological Survey, and have studied Yukon placer gold deposits and the Yukon's placer mining industry since 1993.

I completed my B.Sc. in Geology at the University of Alberta in 1985, and I finished my M.Sc. in Geology (Sedimentology) at the University of Calgary in 1993.

Sarah Laxton

Outreach Geologist

My interest in the Earth Sciences began at an early age when I would sneak rocks into my father’s backpack for him to carry home for me on family hikes. Wanting to know more about the landscape around me, I studied Earth Science and Geography in high school. After taking these courses I knew I wanted to learn more, so I then went on to study Physical Geography and Geology at university. Travelling and outdoor activities are two of my favorite things, and I was able to partake in both while at university. I was able to travel to remote helicopter access locations in the Coast Mountains of British Columbia, the Swiss Alps, Arizona, Himalaya, southern Yukon, and Alaska to participate in research projects, workshops, and conferences. Currently, in my positions as the Outreach Geologist for the Yukon Geological Survey, I am able to share my passion for the Earth Sciences with all sorts of people and I really enjoy my job.

Thomas Hadlari

Project Geologist - Stratigrapher

My name is Thomas Hadlari. I did a Bachelor's degree at University of Saskatchewan in geology (1998). I obtained at Ph.D. in geology at Carleton University in Ottawa (2005).

I currently work in Yellowknife, NT, as a geologist at a territorial government office called Northwest Territories Geoscience Office. I also went to grade school in Yellowknife, so in some respects I came home after University (my family currently lives in Cambridge Bay, Nunavut). Living in the north is important to me because I want my daughter's native heritage to be passed on to her in a way that isn't available in southern Canada.

Joyia Chakungal

Research Scientist

I was born and raised in the suburbs of Toronto, Ontario to parents who both came from southern India, which makes me a first generation Canadian. I grew up in the city where there weren’t many opportunities to do a lot of outdoor activities like camping or hiking. As a family we just didn’t do that sort of thing, at least not often. However, the lack of exposure never stopped me from day-dreaming of one day spending more time in the outdoors and getting to places that people thought I was crazy for wanting to go. I also always had a fascination for ancient things and a natural curiosity for why my surroundings and society in general, are the way they are...

John Clague


I was educated in Los Angeles (B.A. degree), Berkeley (M.A. degree), and Vancouver (Ph.D. degree). I am a currently a Professor in the Department of Earth Sciences at Simon Fraser University (SFU). Prior to my appointment at SFU in 1998, I was a Research Scientist employed by the Geological Survey of Canada. I am passionate about earth sciences I view what I do as a "calling", rather than a 9-to-5 job. I am a scientific "detective" trying to reconstruct the history of planet Earth. My main interests are Ice Ages and hazardous processes, including earthquakes, tsunami, floods, and landslides. Currently, my graduate students and I are conducting research in Alaska, Yukon, British Columbia...

Jenn Sabean

Geotechnical Consultant, Jenn Sabean, M.Sc., P.Geo.

Growing up in Ontario, I loved the family summer road trip to the east coast where I could explore new places and play in the ocean. After high school, I wanted to be closer to the coast, so I began my undergrad at Dalhousie University in Halifax, NS. I took a first year geology class and it was great to learn in the classroom, the laboratory, and outside on all kinds of field trips. Some of the best trips included spelunking through caves in West Virginia, clambering the rocky coasts of Newfoundland, & tracking the entire east coast of North America. I took 4 years of courses to obtain my Bachelor of Science Degree in Earth Science, with a minor in Oceanography by 2001. I did an honors thesis, studying how coastal oil spills affect marsh environments using microfossils.

Jeremy Major

Consulting geologist

My childhood in southern Ontario was spent playing outdoors in summer and winter, on the water and in the snow. Summer camping trips to Georgian Bay with my family gave me the chance to explore the rocky shorelines and forests, a landscape much different than my home in Windsor. I continually took these chances to explore with friends through high school, but after graduation I really just wanted to ski in the mountains so I packed up and moved to Lake Louise. Here I developed a great appreciation for the Rockies and how they came to be. While I knew that at some point I wanted to go to university, I still wasn’t sure what I wanted to study so I held off for a few more years and moved to a number of towns and cities in southern British Columbia working as a ski patroller in the winter and teaching sailing in the summer. After countless trips and adventures I really started wondering if I could pursue my interest in the outdoors in a university setting.

Yvonne Martin

Project Geoscientist

My name is Yvonne Martin and I am an Associate Professor in the Department of Geography at University of Calgary. I grew up in Toronto, and started to first study the earth sciences at the University of Western Ontario. I had some wonderful experiences during my undergraduate degree, including participating in an exchange program to the Geography Department at the University of St. Andrews in Scotland where over a decade later Prince William would walk the hallways (he took Geography at St. Andrews)! When I returned to Canada, I had a position as a Research Assistant at a high-altitude glacier research site near Jasper National Park what an outstanding experience for a young earth scientist! I then attended the University of British Columbia in the beautiful city of Vancouver to undertake my M.Sc. and Ph.D. degrees. This was a wonderful experience for me, and I learned so much about earth science from the outstanding professors there who truly inspired me.

Ian Young

Vice President

I started my career at EnCana in 1985 with a BSc Hons from the University of Calgary, and spent the next twelve years learning the oil and gas business, prospecting throughout western Canada. During that time, I proposed and drilled hundreds of oil and gas wells, some of which were very successful and some of which came up dry. Whatever the result, it was always thrilling to get to drill through the target and wait for the data from the well which would tell the story.

Rachel Newrick

Geophysicist / Geoscientist

I am a scientist, a traveller, a biker and an adventurer. Life is full of variety and there is always something new to learn or to experience. I work for Nexen Inc. as an Exploration Geophysicist which means I help find new pools of oil and gas. After my undergraduate degree in Geology and Honours in Geophysics, I left New Zealand to backpack around the world Central America, Europe and Africa - just for fun! Later I came to Canada and got a PhD in Exploration Seismology (geophysics). While at grad school, I travelled to international conferences, taught field schools and lab classes, and co-authored a textbook on seismic interpretation.

Hassan Odhwani

Processing Geophysicist

Hassan Odhwani graduated in 2005 from the University of Calgary receiving his B.Sc in Geophysics. In October 2005, he was hired as a Seismic Processor for Geo-X Processing (now Divestco Inc.).

Jessica Spratt

Geophysical Contractor

After years of working worldwide as a geophysical research technician with the Dublin Institute for Advanced Studies in Dublin, Ireland, I have recently returned to Canada to work as a self-employed contractor. My specialty is a method called magnetotellurics or MT. MT is a method that provides information on the electrical conductivity of the Earth by measuring the natural time-varying electric and magnetic fields at its surface. These fields are generated from electrical currents that are produced from natural variations in the Earth's magnetic field. One of the things that I really enjoy about my work is the many different applications that exist for MT and that new applications are still being developed. The MT method is commonly used in the deep exploration of the Earth, helping to understand tectonic processes and structure at depths to 100s of kilometers.

Katherine Dunnell

Mineralogy Technician

My original passion was medicine, but after a year of university spent touching 'slimy' things, I decided inorganic sciences were much more appealing. Geology really appealed to me because it is the most tactile of all the sciences, so I switched to an undergraduate program in physical geography.

In between academic years, I spent two summers as a junior mapper living in northern Ontario. From my experiences in the 'bush', I gained a better appreciation for the beauty of the unspoiled north, the ability to cook a roast over an open fire, and a huge disdain for black flies. I also worked two summers at the Great Lakes Institute for Environmental Research...

She joined the Department of Geography at Trent University as a faculty member in 1989. Her research interests in wind erosion lie at the intersection of climatology, geomorphology and soil science. Over a third of the land surface of Earth is arid to semi-arid, and is affected to varying degrees by wind transport of soil particles. Emission of these particles is a key process contributing to desertification and poor air quality in many regions. Cheryl is an expert in wind tunnel simulation of this process, which requires a solid understanding of fluid mechanics and soil physics, as well as considerable technical competence...

Wendy Kemp

Water Resources Program Manager

Groundwater remains an important source of drinking water for the Region and my role as Program Manager of Water Resources is to take actions to ensure that our water resources remain available and safe for future generations. These actions are centred on protecting and monitoring our groundwater, meeting compliance commitments, building and communicating science knowledge. My role is unique in the Region as involves vision to a very multi disciplinary and faceted portfolio. Unlike consulting where projects have a beginning and end, program management requires continuous improvement and evolution. Working as Program Manager requires an ability to make the connections across the entire water resources 'puzzle' and I think that is likely the single challenge that I find most rewarding.

Magdi Widaatalla


My name is Magdi Widaatalla. I was born and raised in a small village called Portbail in the central Sudan, East Africa. I completed all of my schooling (elementary, middle and high) in Sudan. I graduated in 1987 with a B.Sc. (Honour) degree in Geology from the University of Khartoum, Sudan. After graduation, I worked as a Hydrogeologist with a consulting firm in the capital Khartoum. I travelled around and visited many parts of the Sudan drilling water supply and irrigation wells. In late 1980's I went to Saudi Arabia where I spent 9 years working with a consultant.

Pierre Landry


My job in the mining industry provides me with a first hand look at how grass-roots geological work can have an impact on corporate decisions. Not many people realize that one rock sample taken in the field by a geologist can start a chain of events that can help generate or cost a company millions of dollars.

Working as a businessman on Bay St. was always a dream I had as a teenager growing up in the GTA, and throughout my university education I struggled with the idea of being a geologist permanently positioned in the field, so this position as a "Corporate Geologist" allows me effectively use my education while remaining close with family and friends.

Andrée Blais-Stevens

Andre obtained her BSc in geology from the University of Ottawa and her MSc and PhD in Earth sciences from Carleton University. She has been working for the Geological Survey of Canada since 1993 as a research scientist. During her MSc and since hired by the GSC, she developed expertise in Quaternary glacial geology mapping for southern Qubec, southern Prairies (Saskatchewan and Manitoba), central and southwestern British Columbia. For her PhD and later as a GSC scientist, she studied the sedimentology of Saanich Inlet, BC (Ocean Drilling Program Leg 169S), which included submarine landslides that are linked to past earthquake events. She also managed the Climate Change Impacts and Adaptation Research Network on landscape hazards office (C-CIARN LH) based at the GSC. A network designed to bring scientists and decision-makers together on issues related to climate change and its impacts on the landscape.

Mathieu J. Duchesne

Research Geoscientist

I am a Research Scientist at the Geological Survey of Canada in Quebec City. As long as I can remember I have always been attracted by science, especially Earth sciences. How the land and the ocean interact and how the Earth has formed are something that have fascinated me for a long time. What is even more intriguing is how such a dynamic planet has been able to survive and evolved for 4.54 billion years! My research thematic consists in studying the subsurface geology of Canada. In order to do so, I am using a geophysical method named seismic reflection. This method uses sound waves to image the internal structure of the Earth’s crust and gives information about the geological layers that forms it. Seismic reflection uses vibrator trucks on land and airguns at sea. Vibrator trucks and airguns emit waves travelling through the subsurface. Waves are reflected when they hit the interface of geological layers and highly sensitive receivers are collecting reflections coming from depths that sometimes reach more than 20 km.

Virginia Brake

Geoscience Research Professional

I am a physical scientist with the Geological Survey of Canada in Quebec City. My current research focuses on the investigation of vintage and modern seismic reflection and exploration well data in the Arctic.

Hailing from the cold and rocky shores of western Newfoundland, I happened upon my geologic journey by accident. After graduating from Stephenville High School, I headed off to the mainland. It was at Dalhousie University in Halifax, Nova Scotia that I learned that my interest in rocks could actually become a career. I took an introductory geology course simply to fill a science requirement and two weeks later I was wondering why I hadn’t been taking Earth Science all along. Needless to say, I was hooked and I loved the field trips that took us outside and had us see things in a new light; and not just in Nova Scotia- I also had the opportunity to participate in honours field trips in Trinidad and Chile. My first job as a junior geologist was at the Tsa de Glisza emerald project in the Yukon – a place that once seemed so far from home, I thought I would never visit. After completing my undergraduate degree at Dalhousie, I was off to Ontario to work at a junior mining company for the summer. When the summer was over I returned to Dalhousie to pursue a master’s degree in Earth Science studying buried submarine canyons. During my degree I was co-supervised by a researcher at the Geological Survey of Canada (GSC)-Atlantic and was introduced to the GSC work environment. After completing my master’s thesis I went to work at the GSC in Quebec City.

In high school I studied biology, chemistry, and physics so I knew that in university I wanted to pursue science but was unsure which discipline to focus on. At Dalhousie University I signed up for a program called the Dalhousie Integrated Science Program (DISP) that offered a wide range of courses that included Earth Sciences. I discovered that geology not only combines many aspects of science it also requires a level of creativity and an ability to be able to visualize the earth and its many processes. After that year in DISP I decided to persue a Bachelor of Science (Honours) degree in Earth Sciences. Having this degree in geology under my belt opened a world of possibilities after university. One of the first jobs I had was working on a helicopter-based...

I was born and raised in St. John's, Newfoundland, and received my B.Sc. from Memorial University of Newfoundland (MUN), my M.Sc. from the University of British Columbia, and my Ph.D. from MUN. I was in university for twelve years. I became interested in geology while still in junior high school as I was always active in the outdoors and also enjoyed laboratory work, thus geology offered the best of both worlds; a job outside the office in summer, and winters in a lab analyzing rocks collected in the field. Since 1984, I have been a faculty member in the Department of Earth Sciences at MUN (Full Professor since 1995) and have engaged in mineral deposit research in Newfoundland and Labrador, other parts of Canada, Nevada, Botswana and Malaysia.

The earliest I can remember taking an interest in natural history comes from a class project in the 1st grade at elementary school in my hometown of Oxford, Nova Scotia. The entire class built a replica of a stegosaurus made out of wire and paper-mâché. Afterwards, I was sure I wanted to be a palaeontologist.

Although my interest in dinosaurs and fossils waned over the years, I remained interested in the natural history of the Earth and knew that I wanted a career involving the outdoors.
