Professional Summary:

Patient care for a Pathologist is centered on assisting patients and clinicians in the understanding and the use of clinical laboratory data for the planning of therapeutic decisions. My personal specialty focus areas are in renal pathology, immunopathology, and urological pathology. I provide tissue biopsy and clinical laboratory diagnose , prognoses, and therapeutic advice to patients and clinicians on medical and surgical diseases of the kidney (including kidney transplants), bladder, prostate , and testis. These services include the interpretation of biopsies and pathology specimens, consultations on the ordering and/or the results of clinical laboratory lab tests.

Raised in Philadelphia, PA I received my undergraduate education from LaSalle College in Philadelphia in 1973. I attended the University of Pennsylvania School of Medicine and received my MD in 1977. After finishing medical school I did an internship in Internal Medicine at Pennsylvania. I completed my Pathology Residency in anatomic and clinical pathology at the Hospital of the University of Pennsylvania in 1982. During that training I had special concentrations in immunology, HLA testing, and nephropathology. I was a Fellow in Surgical Pathology in 1982-1983. I joined the faculty in the Department of Pathology and Laboratory Medicine at the University of Pennsylvania in 1983. In my first year of appointment I was given the opportunity to do a specially arranged fellowship with Dr. Conrad Pirani in Nephropathology at Columbia University. At Penn I rose through the ranks to become Professor, Vice Chair for Anatomic Pathology-Hospital Services, and Interim Chair of the Department of Pathology and Laboratory Medicine

My research interests are translational and have been focused in the domain of genitourinary pathology. Over the last decade I have had the great opportunity to work collaboratively with a group of image scientists in the development of quantitative image analysis tools tailored to the needs of the digital pathology community. Our vision is to create a new analytic paradigm fusing the data from the quantitative analysis of high resolution images with multidimensional molecular data. This “fused diagnostics” approach will support personalized predictive modeling of disease and its response to therapy. Our collaborative group is funded and is working hard to develop platforms which will support this new way of addressing complex multivariable testing.

Over the years I have had the great good fortune to teach many classes of undergraduate medical students in nephropathology and genitourinary pathology. I have been Program Director of the Surgical Pathology and Immunopatholgy Fellowships at the Hospital of the University of Pennsylvania and instructed 56 Fellows. I have been a member of 9 PhD and 1 MS candidates’ thesis committees. I continue to instruct at the UME, GME, and Graduate student levels.

I have been active in the work of many Pathology societies both as a speaker and in varied leadership roles. My volunteer work has been with the ACSP, USCAP, CAP, Pathology Informatics, ASIP, ICPI, and APC. I was a member of the ASCP Board of Directors for many years and rose through the leadership sequence to be elected ASCP President for 2010-2011. My society work has helped me understand both the challenges and the opportunities which face our profession in these times of great change.

In 2011 I moved from Philadelphia to Buffalo to become Chair of Pathology and Anatomical Sciences at the University at Buffalo, State University of New York. I continue to maintain an active collaborative research program in image science and focus my efforts as Chair on building our clinical, educational, and research programs at UB. I am excited to be part of this great University which is on the rise.
