About Me



I am currently a postdoctoral researcher in the Department of Geoscience at the University of Calgary. I finished my Ph.D. at the University of Washington in 2014, and before that studied geology and biology at Brown University. Through teaching and research, I’ve been able to get involved in field geology on four continents, and have spent the past several summers teaching field camp in southwest Montana.

My research focuses on the chemistry and biology of the oceans during the Permian and Triassic periods – the warm transition interval between the Paleozoic and Mesozoic eras – and particularly on the two major mass extinctions that occurred during this transition and paved the way for our modern marine ecosystem. To study this time interval, I apply a geochemical toolkit to marine sedimentary rocks from around the world. These tools include stable isotopes of carbon and nitrogen from sedimentary organic matter, and a suite of trace elements that shed light on the relationship between algal productivity and available oxygen.
