Polly Arnold is a renowned heavy-element chemist who joined Berkeley Lab from the University of Edinburgh where she is the Crum Brown Chair of Chemistry. Her research focuses on advancing our understanding of the bonding and reactivity of heavy elements, the elements of the f-block of the periodic table. Among her many awards and honors, Arnold is a Fellow of the Royal Society, and was awarded the 2012 Rosalind Franklin Award and Order of the British Empire in 2017 for her outstanding contributions to chemistry and women in STEM.

Ethan received his B.S., M.S., and Ph.D. from the Massachusetts Institute of Technology. He first joined ALS as a postdoctoral fellow and subsequently progressed to a Research Scientist (2014), a Career Staff Scientist (2017), and the ALS Program Development Lead and Science Council Chair (2021). In 2021, he became a Courtesy Faculty member at Oregon State University in the School of Chemical, Biological, and Environmental Engineering (CBEE). His research group focuses on the utilization and development of ambient pressure X-ray photoelectron spectroscopy (APXPS) to study chemical and electrochemical reactions at the solid/gas, solid/liquid, and solid/solid interfaces. He has been recognized for his scientific achievements, receiving the International Solid State Ionics Young Scientist Award, The American Ceramics Society Ross Coffin Purdy Award, the Department of Energy Early Career Research Award, the LBNL Director’s Award for Exceptional Early Scientific Career Achievement, and the International Society of Electrochemistry-Elsevier Prize for Experimental Electrochemistry.
