My Biography & Research


As a hematopathologist, I use pathology techniques to diagnose pediatric leukemia, lymphoma and myelodysplastic syndrome. I also use flow cytometry, a tool for rapid detection and characterization of cells that contribute to disease.

Pathologists are the “doctor’s doctor.” We solve problems and help our clinical colleagues answer questions about patient care. While we don’t see patients, we care about helping them as much as those doctors and nurses who have face-to-face interactions with them every day.

In my free time, I am a photographer and a potter.
