Research Statement

The field of pediatric hematology-oncology offers much opportunity to support patients and their families and perhaps more importantly, the opportunity to make a difference through research and new discoveries. During his fellowship, he was frequently asked by families what triggered cancer to develop in their child. As a result, he became interested in in environmental exposures (e.g., toxicants) on the development of pediatric cancers.

Notably, the incidence of pediatric cancers has steadily increased since 1975, which could suggest that other exogenous factors are accounting for an increasing proportion of cases. For his fellowship research project, he evaluated the association between parental medical radiation exposure and risk of sporadic retinoblastoma in their offspring.

More recently, he evaluated environmental toxicants on the risk of other pediatric cancers and plan to explore the role of environment on pediatric cancer outcomes. Currently, he is seeing patients in the Long-Term Survivor clinic and conducting studies to study late effects from treatment (with particular interest in oncofertility). He hopes to improve the quality of life and overall health outcomes for childhood cancer survivors.
