Bio

Enrique Sosa, Ph.D., is a Lecturer in the UCLA Institute for Society and Genetics, where he teaches courses on reproductive biology, regenerative medicine, stem cells, and the ethical and social dimensions of genetics. Prior to joining the faculty, he conducted research in the laboratory of Dr. Amander Clark at UCLA, focusing on germ cell development, reproductive biology, and stem cell-based approaches to fertility and regenerative medicine. His work has contributed to advances in understanding human and non-human primate germline development and has been published in journals including PNAS, Nature Communications, Cell Stem Cell, and Stem Cell Reports. Through his teaching and mentorship, Dr. Sosa encourages students to examine the scientific, ethical, and societal implications of emerging biotechnologies.
