Radiology Personnel

Mahesh Thapa, M.D.

Associate Professor
Pediatric Radiology


After completing his fellowship in Pediatric Radiology at Seattle Children’s Hospital, Dr. Thapa accepted the position of Acting Assistant Professor at the same institution. In addition to his clinical duties, Dr. Thapa helped organize the monthly resident and fellow teaching conferences at Children’s Hospital. Dr. Thapa began collaborating with the Pediatric Rheumatologists and established a monthly interdepartmental conference to discuss interesting rheumatologic conditions with radiologic and clinical correlation. This was also the inaugural year of the medical student anatomy course with imaging correlation (HuBio 511), which Dr. Thapa helped establish and has actively participated in ever since. In July of 2007 Dr. Thapa became an Assistant Professor and continued his work in medical student/resident/fellow education. Dr. Thapa began collaborating with other departments and obtained additional training in musculoskeletal imaging at Roosevelt Medical Center. In addition to the human anatomy course, Dr. Thapa began educating 4th year medical students by participating in the University of Washington’s Capstone Course (Transition into Residency) and Rheumatology workshops. This was also the first year Dr. Thapa was invited to lecture about pediatric musculoskeletal and informatics topics at several national radiology education meetings, including the American Roentgen Ray Society (ARRS). In the spring of 2009, Dr. Thapa became the Fellowship Program Director of Pediatric Radiology at Seattle Children’s. This has been one of the most rewarding aspects of his career. The new position has given Dr. Thapa more opportunities to work with, mentor and educate fellows and residents. Dr. Thapa’s main areas of expertise include Medical Education, Informatics, and Pediatric Musculoskeletal Imaging.
