Dr. Viorel Popescu, Lab PI, Senior Lecturer and Director of Master of Science Program in Biodiversity Data Analytics (v.popescu@columbia.edu; download CV). I am a broadly trained ecologist and environmental scientist from Romania, who accidentally fell into conservation biology and never looked back. I love herps and cuddling with large carnivores and I spend too much time doing stats. I enjoy spelling trouble for grad students, teaching conservation and ecology, and working with conservation practitioners.
GRADUATE STUDENTS

Matt Huang, MA student, 2025-present; Matt hails from Upstate New York, where he has spent many years contributing to freshwater turtle conservation. As a Cornell graduate, Matt’s interests span wildlife ecology and conservation, and he is interested in exploring the mechanisms and conditions triggering nest abandonment and filial cannibalism in Eastern Hellbenders. When Matt is not in E3B, you can probably find him climbing some rocks!

Luveen Wadhwani, MA student, 2025-present; Luveen holds a Master’s in Computer Science from the University of Texas at Arlington, and has worked as a software engineer in Silicon Valley for 15 years. He embarked on his conservation journey with a Sustainability Certificate from City College of San Francisco. He serves as Chief Technology Officer at Voices for Asian Elephants, overseeing their technology efforts since 2020. At Columbia E3B he will continue to explore AI and machine learning for large mammal movement ecology to power community-led conservation. Luveen is an avid cat person, wildlife photographer, and Bollywood fan. His other interests include yoga, hiking, video games, and cooking (especially Indian, Japanese, and Thai).
