    Research Overview

  • Dr. Bibb's research is aimed broadly at understanding the mechanistic basis of cellular functions and disease with emphasis on features of intracellular signal transduction and protein phosphorylation/dephosphorylation. Multidisciplinary approaches and advanced technologies are combined to identify signaling mechanisms and characterize their physiological functions, from basic molecular interactions to behavior or disease. This research has revealed, for example, common features between brain circuitry function, neuronal injury and oncogenesis. His goals are to import clinical information and perspectives into the lab, model and explore disease causes and then return new treatment approaches and solutions to help patients.
