Dong Chen, Ph.D., is a patent agent in the firm’s Chemical Patent Prosecution group, preparing and prosecuting U.S. patent applications. His practice covers a wide variety of technical areas, including biotechnology, pharmaceuticals (small molecules and biologics), and medical devices.

Prior to joining the firm in 2015, Dr. Chen was a research assistant professor at Northwestern University in Chicago, where he discovered the signaling mechanism leading to excess aromatase and estrogen production in breast cancer.

During his postdoctoral training at Joslin Diabetes Center and Harvard Medical School, Dr. Chen studied the role of phosphoinositide 3-kinase, a critical insulin signaling molecule, in regulating insulin sensitivity in mice under both normal body weight and obesity conditions.

Dr. Chen conducted his doctoral research on insulin signaling pathway and hyperosmolarity signaling pathway, which activate glucose transport via distinct mechanisms in fat cells.
