Dr. Keqi Tang is an electrospray ionization (ESI) mass spectrometry research scientist at Pacific Northwest National Laboratory (PNNL), where he develops technologies and methods for high performance hybrid mass spectrometry and its applications in chemical and biological analyses. Dr. Tang's current research advances ion mobility spectrometry (IMS) instrumentation methods for ultra-high throughput applications in system-biology studies; this research also includes developing a fundamental understanding of both conventional drift tube IMS and high field asymmetric waveform IMS through extensive theoretical modeling and experimental evaluation. Additionally, Dr. Tang is developing and implementing new ESI interfaces for high sensitivity mass spectrometry.
Dr. Tang has been a research scientist at PNNL from 2000. Prior to then, he was a research and development scientist at Thermo Finnigan LLC from 1997; a senior mechanical engineer at YSI Inc. from 1996; a postdoctoral fellow at PNNL from 1995; and a postdoctoral research associate at Yale University's Department of Mechanical Engineering from 1994.
Dr. Tang holds 12 issued U.S. patents, and is a significant contributor to his field with over 50 peer-reviewed publications and numerous invited and conference presentations.
