Biography: Dr. Angela Kadenhe-Chiweshe completed her M.D. degree at the Pennsylvania State University College of Medicine. She entered a categorical general surgery residency at the University of Rochester where her interest in pediatric surgery was solidified. In 2001 she joined the Pediatric Tumor Biology Laboratory as a postdoctoral research fellow under the tutelage of Drs. Jessica Kandel and Darrell Yamashiro. During this time she studied the effects of anti-angiogenic therapy in experimental models of pediatric solid tumors. This work led to key discoveries of how these tumors respond to anti-angiogenic therapy and served as important preclinical data for the Phase II studies for Avastin® (bevacizumab). She also concurrently completed a clinical fellowship in Extra-Corporal Membrane Oxygenation with Dr. Charles Stolar. She went on to complete her general surgery training at Columbia University in 2007, and followed with a clinical fellowship in Pediatric Surgery at the Morgan Stanley Children's' Hospital of New York Presbyterian, in 2009.
