Andrew Y. Koh, M.D.
I grew up in Reno, Nevada. I received my undergraduate degree in Biology from Harvard College. After college, I was awarded a Rhodes Scholarship and studied English Literature (B.A.) at Pembroke College, Oxford University. I then received my medical degree at Harvard Medical School. I completed my pediatric residency and Chief Residency at Boston Children’s Hospital. I then completed a dual fellowship in Pediatric Infectious Diseases and Hematology/Oncology. During this time, I did my post-doctoral work in Dr. Gerald Pier’s lab and focused on understanding the molecular pathophysiology of gut-derived bacterial infections (particularly Pseudomonas aeruginosa) in immunocompromised hosts. Since coming to UTSW, I have extended my work to study bacterial and fungal (particularly Candida albicans) interactions in the mammalian gastrointestinal tract and how these interactions modulate the development of invasive infections in the the immuncompromised host. We are now extending our studies to investigate how the gut microbiome modulates the development of graft-versus-host disease and host anti-tumor response. I am currently an Associate Professor in the Department of Pediatrics and Microbiology at the University of Texas Southwestern Medical Center at Dallas, and am Director of Pediatric Hematopoeitic Stem Cell Transplantation at UTSW Medical Center and Children’s Medical Center Dallas.
