Professional Summary:

As a pathologist in the Department of Pathology and Anatomic Sciences, my clinical duties are primarily in anatomic pathology, including surgical pathology, cytopathology and autopsy. In addition, an important part of our department’s mission is resident and medical student education and I participate formally, giving didactic lectures, and informally, in the gross room and at the microscope.
During the course of my residency, I developed an interest in breast pathology as well as cytopathology, and both of these areas have become a focus of my clinical work today. Since joining the department in 2007, I have participated in the breast pathology service. I provide diagnoses and prognostic information to assist in the appropriate treatment of breast diseases. Being a member of a subspecialty service has allowed me to develop relationships with surgeons and oncologists, which, in turn, facilitates better care for patients.
After practicing pathology for several years and observing some of the inefficiencies that exist in the medical system, I became interested in applying process improvement principles to the laboratory. I have completed a certificate course in Lean Six Sigma through Villanova University, and participate in the department’s Process Improvement committee.
After receiving my medical degree from the University at Buffalo School of Medicine in 2001, I completed a residency in Anatomic and Clinical Pathology and a fellowship in Cytopathology at Cleveland Clinic. I am board certified in Anatomic and Clinical Pathology and Cytopathology.
