I am thrilled to be joining the Fertility and Reproductive Health Services team at Stanford Medicine.  The fellows have access to a world-class teaching hospital and full service research university located in Silicon Valley--a global center for medical entrepreneurship and technological innovation. I am eager to take advantage of the comprehensive training and unique opportunities to become a physician leader in the field of reproductive endocrinology.

Michael Strug, DO, PhD, has a longstanding passion for research within the field of reproductive biology, specifically as it pertains to uterine function and embryo implantation. His research career began as an undergraduate at Rutgers University studying physiologic mechanisms of neonatal exposure to lactocrine-derived hormones and development of reproductive and non-reproductive tissues in animal models. Following his undergraduate training, Dr. Strug gained an appreciation for Reproductive Medicine as a clinical andrology laboratory technician, prompting his pursuit of a career in academic clinical medicine. He completed a medical scientist training program at the Michigan State University College of Osteopathic Medicine and continued at Michigan State University/Spectrum Health for the completion of medical residency in Obstetrics and Gynecology.

For his dissertation research project, Dr. Strug studied the role of the Notch signaling pathway transcription factor RBP-Jk during the establishment of pregnancy through generation of a genetic knock-out mouse model. He determined the importance of Notch signaling during the establishment of pregnancy, repair of the postpartum uterus and, ultimately, correlated his findings of dysfunctional uterine repair clinically in women with unexplained recurrent pregnancy loss. He was awarded a prestigious NIH National Research Service Award (NRSA) F30 fellowship grant for completion of his research. Dr. Strug has been involved in several other clinical and translational projects studying mechanisms of endometriosis pathogenesis and its impact on fertility, along with understanding the effect of exogenous intrauterine hCG infusion on endometrial receptivity. He has presented his work at local and national meetings with receipt of research awards including the Society for Reproductive Investigation Pfizer President’s Presenter’s Award and was a finalist for the Society for the Study of Reproduction Trainee Research Award. He has published his findings in reputable journals including the Federation of American Societies for Experimental Biology Journal, Proceedings of the National Academy of Sciences, The Journal of Clinical Endocrinology and Metabolism, Human Reproduction, and Reproductive Sciences. Lastly, he is dedicated to career development of trainees interested in Reproductive Medicine and has served on the Society for Reproductive Investigation In-Training Committee since 2017.

 I am deeply humbled by the opportunity to work with the Stanford REI team. Their multi-disciplinary approach to both patient care and research is inspiring. I am confident this innovative and team-based environment will provide for an exceptional training experience.

Edward Nguyen, MD, PhD attended the University of Oklahoma, where he graduated with honors with degrees in both Psychology and Zoology – Biomedical Sciences. He continued at the University of Oklahoma in the medical scientist training program, where he earned both his PhD in Cell Biology and his MD degree. This is when he first became involved in the world reproductive biology. His dissertation project was the first to identify and characterize a novel protein found only within the acrosome of sperm, sperm acrosome associated protein 7 (SPACA7). He discovered that SPACA7 is involved in the breakdown of the cumulus oophorus, facilitating fertilization.

Dr. Nguyen then attended the University of Iowa for residency. This is where he developed a passion for teaching, earning the Resident Teacher of the Year award twice. He also continued his research in the field of REI with publications in Fertility & Sterility and the Journal of Assisted Reproduction & Genetics. 

Following residency, Dr. Nguyen went to the University of Washington for a fellowship in minimally invasive and advanced pelvic surgery. He closely worked with a combination of benign gynecologists, gynecology oncologists, and REI specialists to perform a multitude of surgeries. For reproductive surgeries, he gained additional experience performing myomectomies from all surgical approaches, advanced hysteroscopy, surgical treatment of advanced endometriosis, ovarian transposition, and tubal reanastomosis.

 Having the opportunity to train in the Stanford REI fellowship has been a dream come true. The fellows have access to state-of-the-art technologies and facilities, multiple research opportunities, and any resource you could imagine. Not only are the faculty members leaders in the field, but they are also dedicated to the fellows’ education and well-being. The entire division has welcomed me with open arms.
