Janel Long-Boyle, PharmD, PhD

Dr. Boyle is a translational scientist with research interests that include pediatric cancer therapeutics, pharmacokinetics, pharmacodynamics, pharmacogenomics, and clinical trial design. The majority of her research resides within the complex setting of hematopoietic cell transplantation (HCT) and is focused around chemotherapeutic and immunosuppressive agents used in the preparative regimens of pediatric HCT. Specifically, Dr. Boyle studies how covariates such as age, renal function, or genetic variants involved in drug metabolism or distribution may influence drug clearance in the pediatric HCT population.
