Bio:
Her expertise spans electrochemical systems, computational modeling, in-situ spectroscopy, and interfacial characterization. Her research centers on understanding and controlling electrode-electrolyte interfacial processes in electrochemical systems. She employs material engineering, electrolyte surfactants, and potentiodynamic methods to rationally modulate interfacial phenomena. Her current work focuses on developing selective lithium extraction from brines and reactive CO2 capture and conversion technologies. Shreya earned her Ph.D. in Chemical Engineering from the Indian Institute of Technology Delhi, where she advanced photo- and photoelectrochemical processes for CO2 reduction to fuels. By integrating experimental and computational approaches, she focuses on unraveling reaction mechanisms at electrode interfaces, guiding the rational design of efficient, durable catalytic materials and operating conditions that accelerate the transition of these technologies toward industrial deployment.
Abstract:
Efforts to address climate change are increasingly centered on two complementary directions: reducing emissions through industrial electrification and finding ways to transform CO2 into valuable products. Each path, however, brings its own challenges: electrification drives a surge in demand for critical metals like lithium, while CO2 utilization requires efficient capture and conversion technologies. Meeting these challenges calls for innovation across materials design, reactor engineering, and process scale-up. In this seminar, I will share two projects that contribute to these goals. The first focuses on integrated CO2 capture and conversion in electrochemical flow cells, enabling direct transformation of CO2 emissions into useful fuels and chemicals. The second explores direct lithium extraction from geothermal brines, an approach that could provide sustainable access to this critical metal. Together, these projects illustrate how rethinking both carbon and critical metal cycles can support a circular economy and help advance a more sustainable energy future.
