Snee Hall, 2146 112 Hollister Drive
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 held at research associate appointment at the National Institute of Standards and Technology (NIST). Her PhD in Chemical Engineering and earned her MS degrees in Chemical Engineering and Operations Research, all from Columbia University. Her BS in Chemical Engineering is from Michigan State University. She is a recipient of the DOE CAREER Award from the Office of Basic Energy Sciences and serves as the thrust lead for dynamic characterization for the DOE EFRC Multi-Scale Fluid-Solid Interactions in Architected and Natural Materials (MUSE). Her research interests are aimed at advancing a cross-scale scientific understanding of fluid-solid interactions in complex and extreme environments for applications that involve (i) engineering the natural environment for sustainable energy and resource recovery and (ii) designing novel chemical pathways for advancing low carbon and negative emissions technologies.
There will be a reception with food and refreshments at 4:30 pm, following the seminar in Snee 2146 for faculty, staff, and students to meet Dr. Gadikota.
Title: Towards Sustainable Energy and Resource Recovery: Geo-mimicking Subsurface Chemo-Morphological Transformations to Advance Pore-to-Field and Process Scale Applications in Energy and Environment
Abstract: Geo-mimicking the reactive behaviors of fluids in the natural environment allows us to develop a rational basis for designing low carbon energy solutions that harness the subsurface environments. In this context, we predict the role of solid interfaces on the transport and organization of fluids in the subsurface environments for applications related to carbon storage. Recent advances in cross-scale characterization methods now allow us to elucidate the fluid-induced chemical and morphological changes that contribute to observed macro-scale properties of reactivity and flow in subsurface environments. Drawing inspiration from the natural capture, conversion, and storage of CO2 to Ca- and Mg-carbonates via thermodynamically downhill routes, we design reactive separation pathways to remove CO2 from point source emissions and direct the synthesis of clean energy carriers such as hydrogen. We will discuss the alignment of these efforts to advance the scientific basis for developing net zero and negative emissions technologies.
