My Biography & Research


With my colleagues, I aim to decipher mechanisms of disease using a variety of microscopy techniques. I try to determine what abnormalities are present, as well as when and where. I am particularly interested in cancer biology, inflammatory response and musculoskeletal aberrations.

My path to research was paved by a curiosity about mysterious, small-scale failures that lead to abnormal functioning in tissues. I love using a microscope, and I have always wanted to help the sick.

A challenge in many tissue studies is identifying which cells make which product. As a pediatric pathologist, I am pleased to contribute to several such co-localization studies involving lesions caused by immunological and cancerous cell changes.

I have won many awards for molecular pathology teaching, including multiple Gold Apple teaching awards from medical students, and multiple Clinical Pathology Teacher of the Year awards from residents. I have also received the Dean’s Award for Teaching Excellence from the College of Medicine.

Clinical Interests

Microscopic techniques for assessing mRNA expression; protein production and cellular identity in eukaryotic tissues; stem cell development and differentiation using animal models such as the zebrafish
