Research Summary
Before retiring from MIT, Terry Orr-Weaver investigated the processes controlling cell division and cell size during development. She studied the transition from oocyte to embryo, the regulators involved, and how this leads to cell cycle changes from meiosis to embryonic mitosis. She also aimed to delineate the coordination of cell size between tissue layers and the regulation of replication origin activation and replication fork progression.Awards
