In 2017, Dr. Miller created the OvaTools Training Institute which provides academic and theoretical knowledge in Assisted Reproductive Technology and Genetics with the best technical, hands-on training available today in a highly focused supervised learning environment in Fort Lauderdale, Florida.
Paul Brezina, MD
secretary & board member
Paul Brezina is a partner and Director of Reproductive Genetics at Fertility Associates of Memphis. Dr. Brezina completed his fellowship in Reproductive Endocrinology & Infertility at the Johns Hopkins School of Medicine in Baltimore, MD. He earned his undergraduate degree from the University of North Carolina at Chapel Hill. He has an MD/MBA degree from the Brody School of Medicine at East Carolina University in Greenville, N.C., where he also completed his residency in OB/GYN and internship in Internal Medicine. Dr. Brezina currently holds academic appointments at both Vanderbilt University School of Medicine and St. Jude Children’s Research Hospital. Dr. Brezina has published more than 50 research papers, 6 book chapters, and more than 50 scientific abstracts.
He has served as an officer on the Society of Reproductive Endocrinology executive board, chair of the Early Pregnancy Loss Special Interest Group within the American Society for Reproductive Medicine, board member of Advagenix genetic testing company, organizing committee member for the Midwest Reproductive Society International, an elected physician member of the Fertility Pharmacy of America (FPA) Retention Committee (2020-2023) and editorial board member of the Journal of Assisted Reproduction and Genetics (JARG).
Eric Forman, MD, HCLD
Dr. Eric Forman is the Medical and Laboratory Director at Columbia University Fertility Center, he oversees the medical practice as well as the IVF embryology and andrology laboratories. He also actively sees patients with infertility and those seeking to preserve their fertility. Dr. Forman has extensive clinical and laboratory research experience. He has published more than 40 articles in peer-reviewed journals on a wide range of topics in assisted reproductive technology (ART).
He has a special interest in using preimplantation genetic screening (PGS) to optimize IVF and improve selection for elective single embryo transfer (eSET). A randomized controlled trial he led demonstrated, for the first time, that transferring a single chromosomally-normal embryo(link is external and opens in a new window) can achieve the same live birth rates as transferring two untested embryos. After publication of this paper, eSET rates skyrocketed and the American Society for Reproductive Medicine references Dr. Forman’s study in its guideline on the number of embryos to transfer in IVF. He also has an interest in fertility preservation, and a study he led proved that egg freezing using the rapid vitrification technology does not increase the risk of genetic abnormalities in the resulting embryos. This study was cited as a “watershed in ART” by one of the world’s leading experts on cryopreservation.
