She completed her subspecialty training in Reproductive Endocrinology and Infertility focusing on the most advanced aspects of infertility diagnosis and treatment. During her fellowship, she simultaneously earned a Master’s degree in Clinical Epidemiology conducting research on outcomes of in vitro fertilization. She is board-certified in both Obstetrics and Gynecology and Reproductive Endocrinology and Infertility.

Dr. Chung also holds the title of Assistant Professor of Obstetrics and Gynecology in the Division of Reproductive Endocrinology and Infertility at the University of Southern California Keck School of Medicine, where she teaches and mentors trainees in the fields of obstetrics, gynecology, reproductive endocrinology and infertility. She is founder and director of USC’s Fertility Preservation Program and is also Principal Investigator of a number of clinical research projects including egg freezing, novel methods for IVF stimulation, and outcomes of gestational surrogacy. It is her goal to connect with her patients and help make their experience with fertility treatment a warm, personal and successful one.
