Biography

Chinmayee Subban is a Research Scientist in the Coastal Sciences Division and an Affiliate Professor of Materials Science and Engineering at the University of Washington. She is interested in addressing materials challenges related to energy and water, and her efforts span both fundamental and applied research. Chinmayee received her Ph.D. in Chemistry from Cornell University. Following post-doctoral work on Li-ion battery materials at Collège de France, she joined Lawrence Berkeley National Laboratory as an ITRI-Rosenfeld Postdoctoral Fellow and later transitioned to a Research Scientist. At Berkeley Lab she led the development of novel electrode materials for desalination. In 2020 she joined PNNL, where she works on nanoscale ion-water transport, recovery of critical materials from seawater, development of advanced ceramics, materials for desalination and water treatment, ocean CO2 capture, and coastal resilience.
