Expertise

Research Interests

Dr. Poutsma’s group focuses on the application of computational chemistry to problems in organic, inorganic and biochemistry. Currently, the organic projects involve calculating the proton affinities of peptides, the mechanisms of mass spectrometry fragmentation and the mechanisms of peptide hydrogen/deuterium exchange. The goal of these projects is to expand our understanding of peptide fragmentation in order to improve the software used to predict protein sequence from mass spectrometry data.

The inorganic project involves calculating the mechanisms of small aluminumoxide clusters with methane. The biochemistry projects focus on protein folding and are in conjunction with Dr. Lesley Greene of Ïã¸ÛÁùºÏ²Ê×ÊÁÏ.
