Discovery Lab for Reproductive Science and Stem Cell Biology
We are a basic science research lab. Our idea is simple; you can’t treat what you don’t understand. Using scientific research that involves the generation of big data, machine learning and genome engineering in stem cells we are generating new knowledge on the reproductive system across the life course and creating scientific innovations aimed at improving reproductive care. Through years of rigorous, transparent science, our team is committed to changing the paradigm for reproductive care by inventing next-generation solutions to reduce the burden of reproductive disease with the goal of improving human health in this generation and the next.
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.
