Welcome!

I am currently a Research Assistant Professor at Dartmouth College's Department of Earth Sciences investigating paleoclimate and atmospheric pollution primarily in polar and alpine regions. Most of my research is based on geochemical analyses of ice cores, although I also use geophysical techniques, and study marine and lake sediments. My paleoclimate research has been focused on climate variability during the Holocene, particularly in the North Atlantic and North Pacific regions. Natural climate oscillations like the Little Ice Age and Medieval Warm Period provide a longer context for understanding modern climate change due in part to human activities. Furthermore, I am studying how mountain glaciers and the Greenland Ice Sheet responded to climate change in the past, to better predict how they will respond in the future. My atmospheric pollution research has been focused on the trans-Pacific transport of heavy metal (e.g lead, mercury, cadmium) emissions from Asia to North America.
