Orr-Weaver's research concerns the cell cycle and delves into both normal and abnormal aspects of cell division regulation in such diseases as cancer and certain birth defects. She and her collaborators have particularly elucidated the way the cell cycle is coordinated with development.
They have shown that ''cortex'' protein specifically triggers the anaphase-promoting complex in ovaries and the degradation of ''cortex'' protein following egg-activation is strictly controlled. They have also established that ''Inducer of Meiosis 4 (IME4)'' is required for an important step, ''Notch'' signaling, to occur in fruit fly ovaries.
She is the co-author, with Harvey Lodish, of the book ''Model Organisms: Drosophila,'' published in 1997 by Academic Press.
In 1994, Orr-Weaver was one of 16 women faculty in the School of Science at MIT who drafted and co-signed a letter to the then-Dean of Science (now Chancellor of Berkeley) Robert Birgeneau, which started a campaign to highlight and challenge gender discrimination at MIT.
