Alexander Thames

PhD Student, 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.
