The Team
Dr. Peter Crockford
I am an Assistant professor in the Department of Earth Sciences at Carleton University and a guest investigator at Woods Hole Oceanographic Institution (WHOI).
Dr. Nabil Shawwa (post-doc): My research focuses on the sedimentary record of Paleoproterozoic atmospheric oxygen and climate change.
Sabs Wimmer (Ph.D candidate). I received my M.Sc. from the University of Vienna, where I studied Paleoproterozoic snowball Earth glaciations and their interbedded iron formations in South Africa. My current research focuses on tracing environmental change through a systems approach across Earth's Great Oxidation. I aim to improve our knowledge of the function and response of early life to paleoclimates and changes in Earth's chemical composition.
Olivia King (Ph.D candidate): My work is focused on the geochemistry and biostratigraphy of the Carboniferous-Permian carbonates in the Yukon. I aim to understand where these sites in the Yukon were paleogeographically, and how close they were to the continental margin during this time.
Michelle Stevens (M.Sc. candidate). I am currently working on carbonate geochemistry in the Paleoproterozoic and researching the carbon cycle in the aftermath of the Great Oxidation Event. I am focusing on the Lomagundi Jatuli Excursion and its implications for biospheric evolution
Elizabeth Sullivan (M.Sc. candidate). My work is focused on understanding the start of the colloquially named ‘boring billion’. My project is applying a suite of redox and nutrient proxies to the Pethei Group of NWT to better understand this time in Earth’s past.
Derek Wilson (M.Sc. candidate). I completed my B.Sc. in Earth Sciences at Carleton where I used isotopes to investigate how the diet and migratory behaviour of caribou has shifted since the Late Pleistocene in Canada. My current research uses various isotope systems to better understand the migration patterns and diet of narwhal, in response to climate shifts in the Canadian Arctic.
Rizzi Balestra (BSc. Hons). My research focuses on investigating Earth System changes in the Neoproterozoic using different isotope systems (C, O, Sr) on carbonates. I'm currently looking at carbonates of the Kennedy Channel and Ella Bay Formations of Northeastern Ellesmere Island, Nunavut, Canada. These formations are broadly correlated to be Ediacaran in age and my aim is to add new constraints to the age of these units and the geochemistry of the waters from which the carbonates were precipitated.
Jack McPhee (BSc. Hons). For my thesis I am studying the Duhamel Fm. and Wilson Island Group deposited along the shores of Great Slave Lake in the Northwest Territories.
Anna Junek. I’m Anna, a second year undergraduate intern. You can find me all over the lab, usually drilling powders or on the trim saw in the rock room. My current research is on fossiliferous siderite concretions from the Joggins formation in Nova Scotia. Outside of work you can find me crocheting, hiking with my yellow lab, and refereeing rugby.
