Discovery Lab for Developmental Biology and Reproductive Science
Our idea is simple; you can’t treat what you don’t understand. Through over two decades of rigorous, transparent science, our team is committed to inventing stem cell-based solutions to improve human health. Our approach involves the use of biological samples, the generation of big data, machine learning, and genome engineering in stem cells to advance our understanding of the reproductive system across the life course and to apply this knowledge to stem cell models of human development, disease and ovarian aging.
If you are interested in learning more or would like to join our research team please send us an e.mail. To learn more about reproductive health and science research on the UCLA campus, please visit the UCLA Center for Reproductive Science Health and Education.
