Joseph A. Loo Wins 2001 EAS Award for Outstanding Achievements in Mass Spectrometry

Published on: 

Joseph A. Loo will be presented with the 2021 Eastern Analytical Symposium (EAS) Award for Outstanding Achievements in Mass Spectrometry at the EAS Symposium taking place November 15–17, 2021, in Plainsboro, New Jersey.

The annual EAS awards honor analytical chemists who have distinguished career achievements and who have advanced their fields by superior work in developing theory, techniques, or instrumentation.


Loo is a Professor of Chemistry and Biochemistry, and Biological Chemistry (the David Geffen School of Medicine ) at the University of California, Los Angeles (UCLA). He is also a member of the UCLA Department of Energy Institute for Genomics and Proteomics and the UCLA Molecular Biology Institute. He received his BS in chemistry from Clarkson University and his PhD in chemistry from Cornell University. He was a postdoctoral fellow and senior research scientist at Pacific Northwest National Laboratory. Prior to joining UCLA in 2001, Loo was an Associate Research Fellow at Parke-Davis Pharmaceutical Research, with Pfizer.

Loo’s research group uses and develops new mass spectrometry (MS) and proteomics strategies, including top-down MS (TDMS), native MS, ion mobility MS (IM-MS), and label-free quantification methods, to characterize proteins and protein complexes (and their proteoforms) and for the elucidation of protein biomarkers to aid human health studies. Loo focuses on the importance of post-translational modifications, such as lysine acylation, to regulate enzymes and metabolic processes within microbial consortia.

Loo has published more than 330 papers and book chapters. He is on the editorial boards of several scientific journals, including Mass Spectrometry Reviews and Clinical Proteomics. He is the Editor-in-Chief of the Journal of the American Society for Mass Spectrometry. Additionally, Loo has held leadership and advisory positions with scientific organizations, including the American Society for Mass Spectrometry (ASMS) and the US Human Proteome Organization (US HUPO), and his research has been supported by the US National Institutes of Health (NIH), the US National Science Foundation (NSF), the US Department of Energy (DOE), and the U.S. Department of Defense (DOD).
