Research Interests

Signal Transduction and Cell Growth Control

Mechanisms that regulate cell growth in the model eukaryote, the budding yeast S. cerevisiae, with emphasis on the TOR (target of rapamycin) signal transduction network. We are particularly interested in how this network regulates the flow of genetic information and cellular behavior in response to intracellular as well as environmental cues.
