Research Interests:

My lab is broadly interested in how growth factors such as PDGF regulate cell growth. For several years we have been working on how the c-fos promoter is regulated. We discovered a growth factor inducible called SIF which turns out to be composed of STAT family transcription factors. We also study the yeast pheromone response pathway which is remarkably analogous to some aspects of fos regulation. Recent attention has focussed on the role of TFII-I in c-fos regulation. We have also been interested in the c-myc gene and have recently found a novel myc interacting protein using the yeast two-hybrid system. Other interests of the lab include the development of new genetic strategies for studying mammalian cells and elucidating the relationship between growth factor mediated signal transduction and the cell cycle machinery. A new interest of the lab is the development of an annotated database of genes called MedStract in collaboration with a computational linguistics group at Brandeis.
