Dr. Viorel Popescu, Lab PI, Lecturer and Director of Master of Science Program in Biodiversity Data Analytics (v.popescu@columbia.edu; download CV here). I am a broadly trained ecologist and environmental scientist from Romania, who accidentally fell into conservation biology. I love herps and cuddling with large carnivores and I spend too much time doing stats. I enjoy spelling trouble for grad students and teaching conservation and ecology classes, and working with conservation practitioners.
GRADUATE STUDENTS

Arel Triyono, MA student, 2024-present; Arel is a Master’s student from Jakarta, Indonesia and obtained his BS from US Santa Cruz. He has explored several research topics in herpetology including, captive breeding, habitat ecology, and conservation. In this lab, he is interested in researching hellbender ecology for his Master’s thesis. Outside of herpetology, Arel loves playing football and badminton, cooking, and has recently picked up an interest in birding and wildlife photography.

Adrian Casanova, MA student, 2024-present; Adrian is a first year Master’s student who is passionate about wildlife ecology, management and conservation. His experiences and research endeavors on natural resource monitoring throughout South Florida and the Caribbean have strengthened his aspirations in becoming an ecologist. He is interested in wildlife management strategies and solutions, particularly in tropical systems. Outside of his academic pursuits, Adrian loves hiking, playing volleyball, and traveling around the world.

Hannah Hess, MA student, 2024-present; Hannah hails from rural Pennsylvania and has a BS degree from Duke. She has broad interests in mammalian population ecology and is particularly interested in the cascading ecological effects caused by human-wildlife interactions. She enjoys connecting with nature through wildlife photography, hiking, and rock climbing, and she will never say no to the opportunity to travel somewhere new. At home, you will either find her crafting or cooking up a delicious dinner or dessert for her friends!

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;

Brigitte Harbers, MA student, 2024-present; Brigitte is a Master’s student from New York, NY. Her research focuses on disease ecology, particularly brucellosis transmission at the wildlife-livestock interface in Montana’s Paradise Valley. For her thesis, she is combining drone-based aerial surveys, AI-driven elk detection, and rancher-reported data to map elk distribution and identify areas of elevated spillover risk. Brigitte earned her BA in Ecology and Evolutionary Biology from Princeton University, where she studied viral spillover in marine mammals. Outside of research, she has been a lifelong equestrian with experience ranging from international show jumping to ranching, a ski instructor, a Formula 4 driver, and an avid long-distance runner.

Soham Mehta, MA student, 2024-present;
UNDERGRADUATE STUDENTS
Peyton Munroe, Barnard College, Environmental Studies

Marcella Sophia Servedio Willett, Columbia University, Ecology, Evolution and Environmental Biology

Jillian Sullivan, Barnard College, Environmental Studies; Jillian is a senior at Barnard interested in wildlife conservation and ecology at the levels of species, populations, and communities. Her senior thesis in the BEAST Lab seeks to identify predictors of co-occurrence for mammalian mesocarnivores in order to better understand their strategies and conditions for coexistence. A native New Yorker, Jillian loves getting out of the city and into nature so she can nurse her healthy iNaturalist addiction.
