Rebecca Lyczak

In my research lab, we are interested in understanding what genes control early embryonic development and regulation of the cell cycle. We use a combination of genetic approaches with time-lapse imaging of early cell divisions to uncover the role for different genes during development.

Rebecca Lyczak earned her Ph.D in Cell and Developmental Biology from Weill Cornell Medical College and her B.S. in Biology and Education from The College of New Jersey. She did postdoctoral work at the University of Oregon. Members of the Lyczak laboratory study a fundamental question of developmental biology - how does a single cell develop into a complex organism? Using C. elegans as a model, she uses genetic techniques to study the proteins involved in establishment of the anterior-posterior body axis in the one-cell embryo as well as regulation of the cell cycle. Her work has been funded by grants from the National Institutes of Health and the National Science Foundation.
