Xin joined Amgen in 2015 as a Scientist in Inflammation and Oncology Research. In 2019, Xin became a Senior Scientist because of her significant contributions in scientific research and drug development. Prior to that, she spent seven years at Genentech to drive the discovery and development of therapeutic targets in both autoimmune diseases and cancer immunotherapy, with primary focus on modulating T cell responses for disease intervention. Xin is one of the pioneers to identify TIGIT as a T cell co-inhibitory receptor and she is the first author on the first TIGIT paper published in 2009 Nature Immunology.
Xin’s current basic research interest at Amgen aims to explore the mechanisms of how tumor microenvironment impacts antitumor immunity. The network crosstalk in tumor microenvironment among tumor cells, tumor associated stroma, tumor infiltrating immune populations, and endothelial cells in tumor, via metabolites, cytokine/chemokines, and costimulatory/coinhibitory receptors, is important in regulating antitumor effector T cell activity. Xin’s group endeavors to understand the key modulatory pathways and players in tumor microenvironment to provide insights for new target identification and novel therapeutic strategy development.
