Lamont Research Professor, Adjunct Professor
 
My research interests focus on the quantification of earth surface processes using cosmogenic nuclide techniques. Reconstructing continental glaciations on a near-global scale is our core project, with the goal to understand the puzzle about drivers of ice ages. Beyond, I am involved in projects investigating tectonic drivers of uplift (Calabria project, link), the landscape response to faulting processes, refining cosmogenic nuclide techniques and development of new cosmogenic isotope systems.

Lamont Associate Research Professor
 
My main research interests include Quaternary and glacial geology, paleoclimatology, ice sheet dynamics, limnogeology, and using cosmogenic surface exposure dating to obtain chronologies for glacial and ice sheet fluctuations in South America, New Zealand, Arctic Canada, and Alaska. I have worked in eastern Maine, Arctic Canada, South America, and in New Zealand.
 
 
 
 
Lamont Assistant Research Professor
 
My primary interest is the history of mountain glacier and ice sheet activity.  My research at present is focused on developing a detailed 10Be surface-exposure chronology of glacial advances that occurred in the Southern Alps of New Zealand during the Last Glacial Maximum, Late Glacial and Holocene time. These data will help clarify whether the last ice age and subsequent 'abrupt climate change' events were registered coevally between the hemispheres.  In addition to New Zealand, I have worked in northern Maine, Arctic Canada, and Antarctica.
