Roisin Commane

Assistant Professor, 

Dept. of Earth and Environmental Sciences, Columbia University, 

Lamont-Doherty Earth Observatory, 61 US-9W, Palisades, NY

Roisin arrived in the US in 2009 to work at Harvard University where she stayed until July 2018 when she joined the faculty of Columbia University. She has a background in the measurement and modeling of reactive and non-reactive trace gases on planes, ships and in forests. In her spare time, Roisin likes to play (and listen) to Irish music and tries to Irish dance when inspired. She loves hiking and biking in the summer and snow-shoeing in the winter. 



Luke Schiferl

Post-doctoral Research Scientist, Lamont-Doherty Earth Observatory, Palisades, NY

Visiting Scholar: Harvard University, Cambridge, MA

Originally from Wisconsin, Luke completed his PhD in Environmental Chemistry at the Massachusetts Institute of Technology in 2017. At MIT, he focused on understanding various interactions between air quality and agriculture using satellite, ground, and aircraft measurements along with atmospheric chemistry and crop production models. Luke brings his numerical analysis and modeling expertise to the Commane group, working on various projects including improving our understanding and representation of the carbon system in arctic and boreal ecosystems. Luke enjoys traveling, visiting breweries, skiing, and cheering on his teams (Go Badgers!). Webpage

Bronte Dalton

Undergraduate Researcher, Columbia College/Lamont-Doherty Earth Observatory

Bronte is a Junior in Columbia College studying Environmental Science with a concentration in Sustainable Development. She has experience in outdoor and environmental education. Her main areas of interests include atmospheric and oceanic science. As of summer 2018, Bronte is working on mapping reverse trajectory particle dispersion models in order to determine the best locations to place air testing devices for monitoring NYC's pollution output. Outside of her academic interests, Bronte is a Columbia Outdoor Orientation Program (COOP) hiking leader and community coordinator for Columbia's sustainable living and environmental interest house, Greenborough. 



Margaret Powell

unnamed-2

Undergraduate Researcher, Harvard University

Margaret is a senior at Harvard College studying Earth and Planetary Sciences with secondary coursework in Integrative Biology and Mathematical Sciences. Her interests include the biogeochemistry of Arctic carbon and ecosystem-scale modelling. Margaret is currently writing a senior honors thesis in collaboration with the Commane group on diffusive methane fluxes from the Yukon-Kuskokwim Delta of southwestern Alaska. In her free time, she enjoys hiking, running and cooking.
