Research and Development Staff

Sudershan Gangrade is a Water Resources Engineer within the Environmental Sciences Division at Oak Ridge National Laboratory. He has a multidisciplinary background spanning the fields of environmental engineering, hydrology, geology, and geophysics. His research focuses on hydrologic and land surface modeling, hydrodynamic flood simulations, and hydroclimate impact assessment with an overarching goal to develop sustainable solutions for energy-water systems at local, regional, and global scales. He employs high performance computing and modeling tools, data analytics, and visualization techniques to achieve these objectives.

Prior to joining ORNL, he worked as an Environmental Engineer/Geophysicist at an Environmental Consulting firm in Indianapolis, Indiana where he was involved in a wide variety of projects including environmental assessments and remediation, environmental management and litigation support, water resource exploration, karst mapping and preferential flow pathway detection through geophysical imaging. 

Sudershan earned his PhD in Energy Science and Engineering with a focus in Environmental and Climate Sciences at the University of Tennessee, Knoxville in 2019. He also holds a MS in Environmental Engineering and Sciences (2012) from Clemson University, SC, USA, and a BS (B.Tech.) in Environmental Engineering (2010) from the Indian School of Mines, Dhanbad, India.
