Research Interests

I am a trained biomedical engineer with research experience in the molecular mechanisms of sickle cell disease and pediatric T-cell acute lymphoblastic leukemia. My primary research interest is to understand how inherited genetic variation contributes to pediatric tumorigenesis. Towards this end, my research interests focus on:

  • Identifying novel genetic causes of childhood cancer
  • Determining the influence of germline genomics on pediatric cancer susceptibility (i.e. reduced penetrance and variable expressivity)
  • Optimizing germline variant interpretation in an effort to better classify variants and reduce the number of variants of uncertain significance (VUS) reported
