CHR Physicians, Staff & Affiliates
Our Internationally Recognized Infertility Physicians
Two internationally recognized specialists in reproductive endocrinology and infertility currently represent the full-time medical staff of CHR. Norbert Gleicher, MD, CHR’s founder, serves as Medical Director and Chief Scientist. He is a widely recognized expert in the specialty but is also well known for his expertise in reproductive immunology and gyneco-radiology, two sub-specialty areas he helped establish. He served as the founding editor-in-chief of the American Journal of ReproductivJolanta e Immunology and the Journal of Assisted Reproduction and Genetics, the latter now under the editorship of Dr. David Albertini, CHR's Visiting Senior Scientist. In recognition of Dr. Gleicher’s many contributions to in vitro fertilization (IVF), he in 2009 was invited to give the Patrick Steptoe Memorial Lecture to the British Fertility Society, one of the specialty's greatest honors. He is also a recipient of the Austrian Decoration for Science and Art.
David H. Barad, MD, MS, is a Senior Scientist and Director of Clinical ART at CHR. He joined CHR after serving as head of the division of reproductive endocrinology and infertility at Albert Einstein College of Medicine in New York for over 10 years. He also served as a senior investigator at the NIH's Women’s Health Initiative.
With over 400 peer-reviewed publications as author or co-author, Dr. Gleicher is one of the most widely published physicians in the specialty. Similarly, Dr. Barad has greatly contributed to the literature with over 150 publications.
What really differentiates CHR’s physicians from many other practitioners in the field, however, is their equal dedication to clinical care and research. It is this unique combination that characterizes CHR. As new research is developed and applied to clinical care, clinical care improves. As clinical care improves, the word gets out and the demand for clinical care increases. This interdependency of clinical care and research, unique for a free-standing private fertility center, catapulted CHR in a few short years into the position of an internationally recognized clinical and research center in reproductive endocrinology and infertility.

Ali H Brivanlou, PhD
Senior Visiting Fellow
After receiving a master’s degree from the Université des Sciences du Languedoc in Montpellier, France, Dr. Brivanlou went on to earn a Ph.D. in molecular biology from the University of California at Berkeley, in 1990, and then moved to Harvard University as a postdoctoral fellow in the laboratory of Dr. Douglas Melton. He joined the Rockefeller faculty in 1994, was appointed a professor in 2000, and was named the Heilbrunn Professor in 2007. Since 2012, he has also held an adjunct position at Columbia University, where he teaches workshops about Vital Design—Embryology, Architecture, and Innovation.

Min Yang (Mia), PhD
Dr. Yang received her PhD in animal reproduction and molecular genetics from Utah State University in 2017 with the research focus on the oocyte quality. She joined CHR as Junior Scientist in 2019, while maintaining her Postdoctoral Associate position in the Laboratory of Stem Cell Biology and Molecular Embryology at the Rockefeller University. Her research interest lies in the molecular events and cellular interactions that regulate the early embryonic development. Dr. Yang’s ongoing projects include the generation and maturation of human primordial germ cells through the use of human embryonic stem cells. The successful completion of this study will not only further our basic understanding of germ line differentiation, but also inevitably have a strong impact in advancing reproductive medicine and IVF technology.

Lyka Mochizuki, MS
Lyka Mochizuki, MSc, grew up in Japan and in the Philippines and is, therefore, fluent in Tagalog, Japanese and English. Upon arriving in New York City, she completed her undergraduate studies in International Business summa cum laude at Berkley College, at which time she joined CHR for the first time in the marketing department, while concomitantly taking advanced singing classes at Julliard School of Music. She was then accepted into the prestigious Master of Science Program in Negotiations and Conflict Resolution at Columbia University, from where she graduated cum laude in 2019. During the 2018/2019 academic senior year, she spent a mandated externship at the not-for-profit Foundation for Reproductive Medicine, where she was tasked with conducting a formal conflict resolution analysis on a highly controversial issue in infertility practice, the so-called preimplantation genetic testing for aneuploidy (i.e., chromosomal abnormalities) of embryos prior to their transfer into the uterus (PGT-A). Her externship not only produced a detailed report with concluding recommendations for the Board of the Foundation but also to acceptance of a formal paper by a prestigious medical journal in the fertility field, *Journal of Assisted Reproduction and Genetics*. It was this achievement that led CHR to re-employ Ms. Mochizuki after graduation, this time in the function of research associate, with the mandate to further explore the conflict surrounding PGT-A during a one-year research fellowship. CHR investigators have had a long-standing interest in PGT-A and have been essential contributors to the medical literature on the subject.

Peter Hermann, MD, Spanish Representative
Dr. Hermann represents CHR in Spain. He lives and works on the beautiful island of Mallorca, just a short plane ride away from Spain’s mainland, where his practice center, IVF-International, is located. He grew up in Germany, where he initially studied chemistry, and later medicine, at universities of Konstanz, Marburg and Tübingen and in Italy at the historical university of Ferrara and graduated in 1983 in medicine from the prestigious Eberhard-Karls-Universität in Tübingen, Germany. After completing his specialty training in Obstetrics and Gynecology, he founded what became for almost 20 years Stuttgart’s (Germany) largest practice in the field, specializing, amongst other areas, in reproductive endocrinology, infertility and microsurgery. In 1996 he started his own IVF Center in Esslingen, Germany, which in 2005 led to an offer by Europe’s IVF leader, IVI in Valencia, Spain, to join their operations. He then moved to another Spanish market leader, Instituto Bernabeau in Alicante, and only very recently founded IVF-International as his own, independent endeavor. IVF International specializes in supervising and directing difficult infertility cases to appropriately qualified IVF centers all over Europe. In seeking out special expertise for some of his patients, Dr. Hermann contacted CHR and started directing some of these patients to CHR’s New York City center. In the process he repeatedly visited CHR and familiarized himself in detail with CHR’s protocols. This detailed familiarity with CHR operations in the summer of 2009 then led to his appointment as CHR’s representative in Spain.
