Brief Bio

Xiang Li received his Ph.D. in Physical Chemistry from the Johns Hopkins University in 2009. He is an associate research scientist with a joint appointment at the University of Maryland, Baltimore County and NASA Goddard Space Flight Center. His research focuses on the detection of trace element and astrobiologically relevant organic molecules in planetary systems, such as Mars, Europa and Titan. He is especially interested in the instrument development of time-of-flight and ion trap mass spectrometers with various ionization and ion gating techniques.
