Biosketch:
Dr. Chris Chouinard received his Ph.D. in Analytical Chemistry from University of Florida in 2016, where he developed ion mobility-mass spectrometry methods for analysis of small biomolecules in complex samples. He then performed postdoctoral studies in development of Structures for Lossless Ion Manipulations (SLIM) at Pacific Northwest National Laboratory. After four years at Florida Tech, Chris joined Clemson in August 2022.

Research Summary:
Development of high-resolution ion mobility-mass spectrometry methods and technology for biomolecular characterization.
