Summary

John Chang received his undergraduate degree in Biological Sciences at Stanford University.  During medical school at Temple University School of Medicine, he pursued immunology training with Ethan Shevach as a National Institutes of Health-Howard Hughes Medical Institute Research Scholar.  He completed a residency in Internal Medicine and fellowship in Gastroenterology, both at the University of Pennsylvania.  He then undertook postdoctoral immunology research training in the laboratory of Steven Reiner at the University of Pennsylvania. 

During his postdoctoral fellowship, John observed that T lymphocytes undergo asymmetric division during immune responses against microbial pathogens.  The discovery of asymmetric T lymphocyte division was recognized as one of the “Top Ten Scientific Breakthroughs of 2007” by Science.
