Philipp-Alexander Neumann

Short CV

PD Dr. Philipp-Alexander Neumann is a surgeon, physician scientist and PI of his group at the Department of Surgery at the Technical University of Munich, Germany (TUM). Next to his clinical career in surgery, he has specialized on basic and clinical science of colorectal surgery with special interest in inflammatory bowel diseases. During his postdoctoral fellowship at Emory University Atlanta, USA, he has been part in numerous projects related to epithelial wound closure and inflammatory models in the gut. Since 2011 his research has focused on the role of mediators of intestinal inflammation and wound closure. He has successfully established the preclinical murine models of intestinal anastomotic healing in combination with IBD and colitis models. His research group further focusses on elucidating the pathophysiology of intestinal fibrosis formation in IBD and especially Crohn’s disease.
