Tiffany Simms-Waldrip, M.D., is a hematologist and oncologist at Children’s Health℠  who specializes in hematopoietic stem cell transplant (HSCT), with a special interest in patients with bone marrow failure. She is also an assistant professor of pediatrics at UT Southwestern Medical Center.

After earning her medical degree at Texas Tech University Health Sciences Center, Dr. Simms-Waldrip completed a pediatric residency as well as a hematology and oncology fellowship at the University of California, Los Angeles.

“During medical school and residency, I was drawn to the field of oncology. I was intrigued by the pathophysiology of cancer and developed a strong connection to that patient population,” Dr. Simms-Waldrip said.

During her fellowship in pediatric hematology/oncology, Dr. Simms-Waldrip discovered a passion for hematopoietic stem cell transplant.

Dr. Simms-Waldrip has specific research interests in evaluating the role of commensal microbial flora in the development of acute intestinal graft-versus-host disease (GVHD) and identifying improved diagnostic and therapeutic options for complications of HSCT, specifically GVHD and hepatic veno-occlusive disease (VOD).

Dr. Simms-Waldrip has been an American Society of Blood and Marrow Transplantation Clinical Research Training Scholar and received a grant from the National Institutes of Health for developmental hematology training.

With a husband and two young sons, Dr. Simms-Waldrip doesn’t have much alone time, but when she does, she likes to run, do Pilates, or yoga. Her time away from work is spent with her family, whose hobbies have become her hobbies – she is an enthusiastic sports mom.

“I love doing anything with them that puts smiles on their faces,” she said.
