Alexis has worked for over 30 years in human reproduction. After earning her bachelor’s degree in biology from Barnard College, she started her career as an embryologist at the beginning of the Cornell University program with Dr. Michael Bedford. Her work helped to establish the Cornell laboratory as a premier program, and early protocols she helped devise there became the foundation of human embryology and are still used today, worldwide.


Alexis left Cornell to help found the laboratory at St. Barnabas Medical Center. She was then recruited to establish the NYU laboratory, which she directed for almost 20 years. During her time at NYU, she had the opportunity to assist with ground-breaking work on germinal vesicle (GV) transfer; she also helped to establish blastocyst culture at NYU, making it one of the first programs in the US to implement program-wide blastocyst transfer and reduce the number of embryos for transfer. The trophectoderm biopsy/vitrification program she developed at NYU has become the backbone of that clinic—this work improved the pregnancy potential of all patients, but especially older patients whose embryos are plagued by aneuploidy, as well as patients with genetic disease and those who have failed IVF previously.

Alexis works tirelessly in her field: she’s written and presented papers nationally and internationally, has authored or co-authored over 40 publications, and has reviewed papers for various journals. She has consulted at numerous clinics in the US and around the world, as well as serving as the chairperson for both the New York Embryologist Society and Reproductive Laboratory Technologists Society for ASRM. Throughout her career, Alexis has been actively involved in establishing guidelines and developing programs in embryology, a practice she continues today.
