I always remember that there's a patient and family on "the other side" of every biopsy and pathology case that I evaluate. I strive to apply the same rigor and thoroughness in my evaluation and diagnosis of cases that I would expect if the biopsy was for one of my own children.

About

Biography

I’m a hematopathologist, the branch of pathology concerned with diseases of the blood and blood formation (hematopoiesis). Even though our patients don't usually meet us, I would like them to know that Cincinnati Children’s pathologists are incredibly dedicated and work diligently to provide the best possible pathology and laboratory services for our patients.

Hematopathology merges my research interests in the biological aspects of hematopoiesis and cancer with my desire to provide clinical colleagues with the most accurate pathologic diagnoses possible and give patients the best clinical care possible.

I don't usually directly interact with our patients. Nevertheless, I always remember that there's a patient and family on "the other side" of every biopsy and pathology case that I evaluate. I strive to apply the same rigor and thoroughness in my evaluation and diagnosis of cases that I would expect if the biopsy was for one of my own children.

My research is translational and directed toward improving our diagnostic accuracy and understanding of hematologic diseases and cancer.

When I'm not at the hospital, I love being outdoors. Gardening, planting trees and hiking with my daughters is what I enjoy most.
