Researcher, Biological Chemistry
Research Interests
Her research interests include the development of bioanalytical mass spectrometry methods for the structural characterization of proteins and the elucidation of ionization mechanisms for mass spectrometry. She is also interested in developing the Virtual 2D Gel method, a matrix-assisted laser desorption/ionization (MALDI) MS-based surface scanning method in which proteins are desorbed directly from polyacrylamide gels for identifying and characterizing protein isoforms and for measuring protein expression profiles from complex biological samples.
Biography:

She is an author of over 85 scientific publications and currently serves as secretary for the American Society of Mass Spectrometry. Rachel 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 Biomolecular Techniques, and has been on the Features Editorial Board of 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.
