Dr. Greeshma Gadikota is an Assistant Professor and Croll Sesquicentennial Fellow in the School of Civil and Environmental Engineering at Cornell University. Dr. Gadikota directs the Sustainable Energy and Resource Recovery Group. Prior to Cornell, she served on the faculty at the University of Wisconsin – Madison, held postdoctoral research associate appointments at Princeton University and Columbia University, and a research associate appointment at the National Institute of Standards and Technology (NIST). Her PhD in Chemical Engineering and MS degrees in Chemical Engineering and Operations Research are from Columbia University. Her BS in Chemical Engineering is from Michigan State University. Her research focuses on delineating fluid-particle interactions and transformations of matter in engineered and subsurface processes for applications related to energy and environment. For RADIATE, she will probe the mechanisms of plastics deconstruction in multiphase environments using cross-scale X-ray and neutron scattering measurements. She is a recipient of the DOE CAREER Award, AICHE Sabic Award for Young Professionals from the Particle Technology Forum, an invited participant in the NAE Frontiers of Engineering, invited speaker at the NAE German-American Frontiers of Engineering Symposium, was recognized as a Scialog Fellow in Negative Emissions Science, and received the 2020 Minerals Young Investigator Award.
