Researcher Dr Rachel Ogorzalek Loo is recipient of the American Society for Mass Spectrometry (ASMS) Al Yergey Mass Spectrometry Scientist Award. 

The award recognizes “unsung heroes” for their dedication and significant contributions to mass spectrometry-based science.  

Rachel is a researcher in Professor Joe Loo’s group in the Department of Chemistry & Biochemistry and is also a member of the UCLA Department of Biological Chemistry, David Geffen School of Medicine. She is an author of over 125 scientific publications and is a former member of the Board of Directors for ASMS. She has been a member of various working committees with the Association of Biomedical Resource Facilities (ABRF), serves on the editorial board of the Journal of the American Society for Mass Spectrometry, and previously served on editorial boards for Spectroscopy, Journal of Biomolecular Techniques, and on the Features Editorial Board for Analytical Chemistry

Before joining UCLA, she was Director of Mass Spectrometry for the University of Michigan Protein and Carbohydrate Structure Facility, University of Michigan (Ann Arbor, MI), and later moved to Parke-Davis Pharmaceutical (Pfizer Global Research, Ann Arbor, MI) as a Research Associate.

2020 Recipient: Rachel Ogorzalek Loo

The Al Yergey Mass Spectrometry Scientist Award is sponsored by ASMS to recognize dedication and significant contributions to mass spectrometry-based science by “unsung heroes”. This award is named in memory of Al Yergey a well-respected scientist who was known as a dedicated mentor.

Dr. Rachel Ogorzalek Loo is the 2020 recipient of the Al Yergey MS Scientist Award. She has been involved with mass spectrometry for nearly thirty years, currently serving as a Research Biological Chemist at UCLA. She has co-authored over 125 peer-reviewed scientific papers and has significantly contributed to our understanding of electrospray ionization, charging, and protein structure.  Dr. Loo was one of the first to pursue the idea that ESI charge state distributions depend on protein solution phase structures. She continues to explore the fundamental aspects of ESI, proposing new mechanisms in a Critical Insights article for JASMS in 2014.

Dr. Loo has also served as a mentor to countless graduate students, postdocs and scientists and given her time to serve the mass spectrometry and greater scientific community at large.
