The Lithium “Gold Rush” presented by:  Dr. Aaron Celestian

Dr. Celestian’s current research is how minerals interact with their environments and with living things, and how those minerals can be used to solve problems like climate change, pollution, and disease.  His on-going research in experimental design, real-time material characterization, mineral discovery & application, and the functionalization of minerals is developing novel nano-crystalline Earth materials into functional materials for a wide variety of demanding applications.  Dr. Celestian holds adjunct teaching and research faculty positions at the University of Southern California and is an Affiliate Research Scientist at NASA’s Jet Propulsion Laboratory.  In addition to research, Dr. Celestian oversees the Gem & Mineral Hall at the Natural History Museum of Los Angeles and regularly develops mineral science exhibits.

***Members who want to do this must respond to our Programs chair, Rudy Lopez at  no later than Tuesday April 6, 2021.  Please include “April, ZOOM Meeting” in the subject line of your response. This response date will allow time for us to send you the information needed to participate in the ZOOM meeting and also will allow time to get everything organized at Caltech.
