Research Emphasis

Dr. Lei’s research focuses on mammalian ovarian reserve formation, maintenance, and its associated female reproductive health issues. The Lei lab is particularly interested in understanding 1) how the intercellular transport of organelles and cytoplasm during ovarian reserve formation in fetal ovaries influences ovarian function and female fertility in adulthood; 2) the roles of organelle organization and RNA storage in ovarian reserve maintenance and activation in adult females; and 3) cellular origins of ovarian cancer. Dr. Lei’s research has been reported in Science, Proceedings of the National Academy of Sciences of the USA (PNAS), Development and Biology Open, etc. Dr. Lei has been peer-reviewing research articles for Science, PNAS, Nature Medicine, etc. and research grants for the National Institutes of Health.
