Jesus D Gomez Velez

Dr. Jesus Gomez-Velez is a Senior R&D Staff in the Watershed Systems Modeling Group within the Environmental Science Division at Oak Ridge National Laboratory. His research goal is to improve our mechanistic understanding of how water, solutes, and energy move through natural and urban environments and the implications of these transport processes for humans and ecosystems. To this end, he combines numerical modeling, data mining and assimilation, machine learning, and field and laboratory observations.

Before joining ORNL in August 2022, Jesus was an Assistant Professor in the Department of Civil & Environmental Engineering at Vanderbilt University, where he led the Environmental Flow and Transport Laboratory. He holds joint faculty appointments at Vanderbilt University and Virginia Tech. 

Jesus received a Ph.D. and M.S. in Earth and Environmental Science from the New Mexico Institute of Mining and Technology, an M.S. in Applied Mathematics from the same institution, and a B.S. in Civil Engineering from the National University of Colombia at Medellin. He was a National Research Program postdoctoral fellow at the U.S. Geological Survey.
