Brad joined Amgen in 2016 as Director of Discovery Attribute Sciences where he directs a group in ‘Proteomics & Protein Analytics’ at the South San Francisco campus. His proteomics group supports the discovery drug pipeline in protein target expression analysis, basic mechanism of action studies, protein interactions networks, targeted protein degradation, and biomarker discovery and immuno-peptidomics, among other topics.  The protein analytics group focuses on protein reagent characterization of complex antibody and protein conjugates.

Brad received his PhD in Chemistry at MIT in 1983 and did a SERC postdoctoral fellowship at Cambridge University where he studied bioactive peptides, protein structure and protein phosphorylation.  From 1985 to 2000, Brad was a faculty member in the Department of Pharmaceutical Chemistry at UCSF where he pioneered studies in the structure and function of surface Neisseria and Haemophilus spp. bacterial glyconjugates in infectious diseases, developed protein crosslinking strategies, and continued his studies to advance protein mass spectrometry and emerging proteomic technologies. Before joining Amgen, Brad was a Professor and director of Chemistry at the Buck Institute for Research on Aging where he investigated the basic biology of aging and age-related disease, with a focus on protein posttranslational modifications, protein aggregation, and the remodeling of the cellular proteome in various aging paradigms.  In addition, he was a key participant in a large NCI proteomics network (CPTAC) on developing and implementing mass spectrometry-based technologies for blood-based cancer biomarker discovery.
