Andrew Koh, M.D., is the Director of Pediatric Hematopoeitic Stem Cell Transplantation at Children’s Health℠ and specializes in Pediatric Hematology/Oncology and Infectious Diseases. He is also an Assistant Professor of Pediatrics and Microbiology at UT Southwestern Medical Center.

After receiving his medical degree from Harvard Medical School, Dr. Koh completed a pediatrics residency at Children’s Hospital of Boston, where he also performed his Pediatric Infectious Diseases and Pediatric Hematology/Oncology fellowship training.

“As with most people who are drawn to medicine, I wanted to make a difference and help people,” Dr. Koh says. “To me, there is no greater opportunity to make a difference than to cure a child of a potentially fatal illness. It is a privilege and an honor.”

Dr. Koh researches how gut microbiota affect the development of infections and of graft-versus-host disease, a complication in which the transplanted immune system (the graft) attacks the patient recipient (the host).

In 2015, Dr. Koh was the senior author of an article in Nature Medicine showing how to reduce the presence of a fungus that causes infections and complications in cancer and stem cell transplantation (SCT) patients, decreasing mortality by 50 percent.

During medical school, Dr. Koh took two years off to pursue musical interests, something he still enjoys when he’s not working. Dr. Koh plays guitar and piano, sings, writes music and has a recording studio in his home.
