My research is at the intersection of machine learning, computer vision, earth sciences, and high-performance computing. I am interested in efficient unsupervised and supervised learning methods for leveraging ever growing datastores of spatio-temporal earth science observations, forecasts, and projections to understand our environment. Recent projects have included developments of novel deep learning methods for spatio-temporal downscaling, physical model emulation, generating virtual sensors, and cloud tracking.
Thomas is a research scientist at the NASA Ames Research Center and Bay Area Environmental Research Institute within the NASA Earth Exchange (NEX) in Mountain View, CA. In August 2018 Thomas earned a Ph.D. in Interdisciplinary Engineering from Northeastern University working in the Sustainability and Data Sciences Lab advised by Auroop R. Ganguly. During graduate school his research won runner-up best paper and runner-up best student paper awards at SIGKDD 2017, outstanding graduate researcher at Northeastern University in 2018, and served as an elected student member of the committee on Artificial Intelligence Applications to Environmental Science for the American Meterological Society (AMS). Prior to graduate school he worked at multiple startups in the Boston area, including the MIT Media Lab spin-out Affectiva. He completed his bachelors in mathematics at the University of Maryland College Park in 2012.
