Summary
👤
Senior🎓
Top SchoolEthan Welty is a postdoctoral researcher and environmental scientist with 13 years of experience applying glaciology, geospatial analysis, and software development to climate and conservation problems. Based in Zürich at the World Glacier Monitoring Service and the University of Zurich, he designs data submission, validation, and publishing pipelines for global glacier observations while continuing a research program extracting high-resolution glacier dynamics from time-lapse and crowd-sourced imagery. He co-founded Falling Fruit and Community Fruit Rescue, blending technology and community action to map edible urban landscapes, and has made substantive open-source contributions as a backend developer and data engineer to projects like the Public Utility Data Liberation Project (pudl). An award-winning documentary photographer and seasoned field scientist, Ethan brings a rare mix of hands-on fieldwork (from snorkeling river surveys to glacier time-lapses), data engineering, and visual storytelling to environmental research and public-facing conservation efforts.
