Clinical Pathology

I am a board-certified clinical pathologist specializing in transfusion medicine and cell therapy. My work involves delivering clinical care to patients, overseeing blood collection services and blood bank operations, offering consultation on transfusion-related issues to other clinical teams across the Memorial Sloan Kettering Cancer Center system, and providing medical and operational oversight in the cell therapy laboratory.  

I am passionate about quality assurance, and in collaboration with my colleagues at the Department of Laboratory Medicine, I strive to ensure that we are providing the best quality of care to our patients while adhering to the most stringent quality standards. My research interests include finding better ways to predict and improve the viability of hematopoietic stem cells in stem cell transplantation, CAR T cell manufacturing, and utilizing virus-specific cytotoxic T lymphocyte therapies for the treatment of viral diseases.


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
