Research

The Clowers Research Group combines ion mobility spectrometry (IMS) and mass spectrometry (MS) with optical fragmentation mechanisms to probe complex chemical systems in the gas phase. These hybrid methods address a range of chemical problems spanning from the fundamental to the applied. A few of these research topics include carbohydrate structure determination, intelligent stereochemical ligand development, gas-phase clustering equilibria, and selective ion chemistry for threat detection. In addition to focusing on gas-phase ion behavior, students in my group hone skills related to sample ionization, instrument construction, experimental design and chemometric data analysis. These skills help deliver solutions to a range of chemical problems across domains including national security, environmental analysis, and bioanalytical chemistry.
