Changxian Shen, Ph.D., began his biology studies for B.S. at Hunan Normal University in Changsha, China, and M.S. at Beijing Institute of Microbiology & Epidemiology in Beijing, China. After that, he moved to Ulm of Baden-Württemberg, Germany, to complete his Ph.D. in the field of molecular cancer biology at University of Ulm. He finished postdoctoral training at St. Jude Children’s Research Hospital in Memphis, Tennessee. He followed up with his studies in cancer biology and translational cancer research at Nationwide Children’s Hospital and The Ohio State University in Columbus, Ohio.

Dr. Shen’s research has been focused on the roles for cell growth signaling pathways (including RAS-MAPK and PI3K-mTOR) in the regulation of cell cycle progression and DNA damage repair. Dr. Shen’s long-term goals is to elucidate the mechanisms of tumorigenesis and find better therapies for the aggressive and hard-to-treat tumors, such as pancreatic and lung cancers, by exploring the genetic and epigenetic alterations of cancer cells.
