About me

  • Co-Director, UPenn HHT Center of Excellence
  • Assistant Director of Scientific Outreach, Penn Medicine BioBank
  • Assistant Professor of Medicine (Translational Medicine and Human Genetics)
  • Assistant Professor of Medicine in Genetics

As a Clinical Geneticist at Penn Medicine, my goal is to provide diagnostic workup and medical management for any patient with a genetic or inherited condition. With my training in Medical Genetics and Internal Medicine, I see both adult and pediatric patients with any suspected genetic disorder, and have a special interest and expertise in the management of patients with ciliopathy conditions (disease affecting the primary cilium). When visiting our clinic, you can expect a detailed review of your medical and family history, a thorough physical exam, excellent genetic counseling from our team of Genetic Counselors, and a clear and comprehensive plan for diagnostic workup and management. 

My education and training

  • Medical School: University of Pennsylvania School of Medicine
  • Residency: NewYork-Presbyterian/Columbia University Medical Center
  • Residency: Children's Hospital of Philadelphia
  • Fellowship: Children's Hospital of Philadelphia
