Siam Oottamasathien | Professional History

Dr. Oottamasathien, is the Director of Innovation and Technology Development in the Department of Urology at Boston Children’s Hospital and an Associate Professor of Surgery at Harvard Medical School. He is a board-certified pediatric urologist specializing in complex hypospadias surgery and general pediatric urologic conditions. Dr. Oottamasathien earned his medical degree from the University of Colorado School of Medicine and completed his urology residency at the University of Colorado at Denver and Health Sciences Center. He then completed his pediatric urology fellowship at Vanderbilt University in 2007. From 2007 to 2017, he was the Director of Pediatric Urology Basic Science Research at the University of Utah and for the past four years at Massachusetts General Hospital. His research involving models, mechanisms, and new generation therapeutics to treat bladder inflammation and pain conditions (Interstitial Cystitis/Painful Bladder Syndrome) set the foundation for obtaining both K12 and R01 grants from the NIH. Recently his work on radiation-induced proctitis was awarded another 5-year R01 grant from the NIH, in conjunction with collaborators at the University of Utah. Currently, his research efforts revolve around models and mechanisms that drive various urologic conditions and developing innovative biopolymers for therapeutics and/or drug delivery.

Simply, it’s our kids. When I was an intern and resident in general surgery, I found myself truly loving my pediatric surgery rotations. I quickly realized that I loved to take care of the kids. Now a father of three, I’ve gained an even deeper appreciation about their health and well-being. I will continue to devote my career at BCH towards caring for our children with urologic needs.
