Huolin Xin, Associate Professor

Huolin Xin graduated from the Physics Department of Cornell University in 2011 and joined University of California, Irvine in 2018. He received an accelerated tenure promotion to Associate Professor in 2020. Prior to becoming a professor at UCI, he worked at Brookhaven National Laboratory as a scientific staff member and a principal investigator from 2013 to 2018. His primary field of expertise lies in developing novel 3-D, atomic-resolution, and in situ spectroscopic and imaging tools to probe the structural, chemical, and bonding changes of energy materials during chemical reactions or under external stimuli. His research spans the areas from tomographic and atomic-resolution chemical imaging of battery and fuel cell materials to in situ environmental study of heterogeneous catalysts, and to the development of deep learning-enabled self-driving TEM. He was named the Highly Cited Researcher by Clarivate in 2011. He received the DOE Early Career Award, MRS Outstanding Early-Career Investigator Award, MSA Burton Medal, UCI Distinguished Early-Career Faculty Award, MAS Distinguished Scholar Award, Castaing Award, and MSA Presidential Scholar Award. His work has twice been selected as the Top-10 Scientific Achievements in 2014 and 2019 by Brookhaven National Lab. His research has resulted in more than 200 peer-reviewed publications and 1 patent, 35 of which are published in Science/Nature sister journals (corresponding author on 10 of the 35). To date, he has graduated four Master's students and three Ph.D. students. Two of his group alumni have won the “Presidential Student Award” at the annual M&M conference based on their research in Xin group. He currently operates a group of four postdocs and six students and he has multiple open positions for students and junior/assistant specialists who are interested in deep learning and energy materials-related research.
