Xin He is a postdoctoral researcher in Robert Kostecki's group, using in situ and ex situ synchrotron technique, spectroscopy and imaging methodologies to sense physical or chemical properties of advanced materials and electrochemical interfaces. Xin received his Ph.D. degree in physical chemistry from the University of Muenster (Germany) in 2016. His research interests focus on electrochemical energy storage, especially in lithium-ion battereis. He applies new experimental approaches to characterize interface issues affecting rechargeable solid state battery performance. He has (co-)authored more than 30 papers in refereed journals, 4 patents and invention disclosures.
