How and why are polar and alpine landscapes changing? 

How is climate change affecting polar ecosystems and human populations?

Why do the poles matter for people who live in the temperate zone? 

Was Mars ever “warm and wet” or has it always been a glacial/permafrost world? 

     My research and teaching aim to answer these kinds of questions by focusing on understanding the structure, origins, and future responses of polar and alpine landscapes to changing climate conditions using satellite observations, embedded sensor networks, and laboratory analyses of sediments, water, and ice. This wide range of technical approaches is synthesized into a probe of surface composition, climate history, and future response using remote sensing and GIS analyses. By combining geological, ecological, remote-sensing, and climatological tools, my research program also works to advance the fundamental geoscience that underlies geomorphology, paleoclimatology, and planetary exploration. 

    My group is always looking for enthusiastic students who are keen on exploring Earth's polar regions and Mars. Feel free to contact me with questions.
