My Notes
I have worked at Stony Brook University Medical Center since 1988, spending a good deal of that time directing the Reproductive Endocrinology program in the Department of Obstetrics & Gynecology. My main interest has been in helping people establish families, with special focus on addressing delays in conception and repeated miscarriage.
I grew up in a medical household. My Dad was a general practitioner in the days when doctors made house calls. My own medical practice style, as well as my life's habits and goals have been strongly influenced by that experience.
I have always been interested in the "why" of things and have had a strong desire to delve deeply into issues. I have been active for many years trying to understand the basis of human infertility, both from the perspective of addressing the problems of individual people and in the laboratory. Being a social person, I have enjoyed the opportunity to interact with a varied group of individuals with many backgrounds, both locally at the Medical Center and nationally. I have served as President of the American Society of Reproductive Immunology, a group whose primary interest has been in understanding the mechanisms of fertilization failure and why pregnancies miscarry.
I consider this a special community and have been happy to have had the opportunity to play a role in its mission to provide excellent clinical care, advance medicine through the acquisition of new knowledge, and to transmit that knowledge to future doctors.
