Abhijeet earned both his M.Sc. and Ph.D. in Civil and Environmental Engineering from Michigan State University, with a focus on Agriculture and Water Resources. Outside of work, Abhijeet enjoys biking, hiking, and exploring new places.

Alexander Thames
PhD Candidate, Geosciences and Climate Science Dual Title
Alex Thames is an interdisciplinary scientist with interests ranging from the influence of weather on water resource planning to the evolution of Earth's volatile flux as a function of its deep water cycle. Specifically, he is interested in how synthetically generated data sets can provide exploratory insights into poorly constrained physical processes. When not acting as a scientist, Alex can be found watching and critiquing science-fiction, fantasy, and horror content with his wife, doting on his dog, and coding small videogame projects.

Ava Spangler
PhD Candidate, Geosciences and Climate Science Dual Title
Ava is pursuing a PhD in Geosciences and Climate Science. Her interdisciplinary research focuses on decision-making tools for urban resilience against climate change. Currently, her work is focused on adaptations to urban flooding in Baltimore. Ava previously earned a B.Sc. in Civil Engineering from the University of Colorado Boulder, where her studies focused on hydrology and water resources. Ava is a fan of chocolate chip cookies, trail running, and yoga.

Ethan Heidtman
PhD Student, Geosciences and Climate Science Dual Title
Ethan Heidtman is pursuing his Ph.D in Geosciences at Penn State. Before coming to PSU, he attended the University of Maryland, College Park, and received a BSc in Geology and a BSc in Atmospheric & Oceanic Science. His research interests include exploratory modeling of human-natural systems, hydrology, and meteorology. In his free time, Ethan enjoys watching and playing soccer, golfing, and spending time with family.

Tsunami Sharmba
PhD Student, Geoscience and Climate Science Dual Title
Tsunami is pursuing a PhD in Geosciences and Climate Science. Her interests are interdisciplinary ranging from studying the impacts of and reactions to climate change, as well as the ethical use and allocation of resources. Before joining the Geosciences department, Tsunami earned a Master of Science in Energy and Mineral Engineering, a Bachelor of Science in Environmental Systems Engineering with honors, and a Bachelor of Science in Philosophy from Penn State. Tsunami also completed an undergraduate minor in Watersheds and Water Resources. Outside of work, Tsunami enjoys baking, video games, and weekend getaways.
