Research Information

Research Interests

We are motivated to develop mass spectrometry-based analytical methods for studying protein post-translational modifications, protein structural dynamics, and proteome dynamics. Mass spectrometry is the pre-eminent technology in analytical protein chemistry. However, current methods on the front end of mass spectrometry analysis are not fully utilizing the potential of modern mass spectrometry technologies. Development of advanced analytical methods on the front end of mass spectrometry analysis is, therefore, critical to advancing the study of proteins. We have innovated diverse mass spectrometry-based methodologies for protein/proteome analysis, resulting in over 120 peer-reviewed articles. Our current research interests include: 1) Identifying isoaspartic acid (isoAsp) residues in proteins involved in neurodegenerative diseases and understanding the consequences of isoAsp formation, and 2) Developing an analytical platform for identifying the targets of drugs.
