Jixin was trained as a protein biochemist and cell biologist with extensive experience in post-translational modifications, cell signaling, protein degradation, and genome editing. During his Ph.D. and postdoctoral fellowship, Jixin studied the biochemical mechanism and functional impact of novel proteins involved in human infectious and genetic diseases. Upon joining Amgen in 2018, Jixin has applied his expertise to developing novel therapeutic strategies to treat cardio-metabolic disorders. He is especially interested in harnessing the protein quality control and protein degradation machineries to improve cardiac function in patients suffering congestive heart failure, a rapidly growing epidemic that affects many individuals and a leading cause of death worldwide.
