Dr. Rothman’s award-winning research details how vesicles -- tiny sac-like structures that transport hormones, growth factors, and other molecules within cells -- know how to reach their correct destination and where and when to release their contents. This cellular trafficking underlies many critical physiological functions, including the propagation of the cell itself in division, communication between nerve cells in the brain, secretion of insulin and other hormones in the body, and nutrient uptake. Defects in this process lead to a wide variety of conditions, including diabetes and infectious diseases such as botulism.
In 1995, Dr. Rothman joined the Amersham PLC scientific advisory board. When Amersham was acquired by GE Healthcare in 2003, Dr. Rothman was appointed as the Chief Science Advisor to GE Healthcare.
