I’m a board-certified pediatric hematologist-oncologist, or blood doctor. Early in my career I worked as an oncologist and bone marrow transplant doctor. I now specialize in pediatric hematology with a focus on hemostasis and thrombosis (blood clotting disorders). I am also a member of the Cerebrovascular Program at Cincinnati Children’s, where I work to improve the diagnosis and management of pediatric stroke.
I chose my career because I love children — especially adolescents and young adults. I am inspired by the honesty and courage of my patients. Having to take medicine every day or having limitations on activity or endurance is difficult. However, I believe that people want to be healthy and strong, and by working together we can find a way forward. When patients, families and medical staff work together, the impossible can become possible.
I am always looking for ways to improve outcomes. In addition to my clinical practice, I conduct research and direct a clinical laboratory where we look for solutions to bleeding and clotting problems. My team and I are trying to understand the connections between diseases like inflammatory disorders or sickle cell anemia and clotting. We also look for better ways to diagnose problems with platelet function.
Outside of the hospital, I enjoy cooking, growing herbs and reading mystery books. I also like to rehab old houses.
