Dr. Yu Xia earned her B.S. (1999) in Chemistry from Lanzhou University, China, M.S. (2002) from Shanghai Institute of Material Medical, CASs, China, and Ph.D. (2006) under the supervision of Professor Scott A. McLuckey from Purdue University, USA. After postdoctoral training with Professor Graham R. Cooks at Purdue, Dr. Xia took positions as Assistant and Associate Professor at the Department of Chemistry, Purdue University (2009-2017). She joined the Department of Chemistry, Tsinghua University as a Professor afterwards. Her research directions include the development of radical reaction mass spectrometry systems and methods for lipidomics and proteomics applications. Her work has resulted in over 100 peer-reviewed publications and book chapters. Dr. Xia received ASMS Research Award (2013) and served as the Secretary of ASMS (2015-2017). She received the support from the National Natural Science Foundation for Excellent Young Scholar (2017). She is the Vice President for Diversity and Inclusion of the International Lipidomics Society and currently serves on the editorial boards of the Journal of the American Society for Mass Spectrometry2019-2024and International Journal of Mass Spectrometry (2020-2023), respectively.
