Research Interests

My glaciological interests include extracting high-resolution time series of tidewater glacier dynamics from time-lapse photographs, harnessing crowdsourcing platforms to tackle difficult-to-automate image processing needs, and evaluating internet photo collections as records of subtle landscape changes. As a side project into the social dimensions of climate change, I recently completed a survey of climate change knowledge, attitudes, and media habits in the local (Boulder, CO) community. Putting my skills in geography to work in support of the urban agriculture movement, I am building an inventory of urban arable land, with corresponding yield estimates, across the city.


Born in the '80s. Raised in France. Earned degrees in physics and mathematical biology at the University of Washington while working as photo editor and photographer for the school's daily newspaper. Snorkeled northwest rivers and mapped fish distributions for the US Geological Survey. Now I study tidewater glacier dynamics in the Arctic with time-lapse photography and photogrammetry for a PhD at the University of Colorado. I climb mountains, play classical guitar, dabble in fermented foods (and beverages), commute by bike, and forage for fruit. I walk, talk, eat, and photograph my way across continents.
