Molecular Mechanisms of Signal Transduction
After receiving a B.S. in Microbiology and a M.S. in Biochemistry I received a Ph.D. in Cell and Developmental Biology from Harvard University in 2001 where I studied core signaling pathways regulating cell survival in the laboratory of John Blenis. I then moved to Seattle where I studied signaling pathways regulating brain development for two years in the laboratory of Jonathan Cooper at the Fred Hutchinson Cancer Research Center. I then moved back to Boston where I completed my postdoctoral training at Harvard Medical School in the laboratory of Steven Gygi where I studied mass spectrometry and proteomics for three years. In 2006 I joined the Department of Biology at the University of Vermont.
Research in the Ballif lab is primarily focused on elucidating molecular mechanisms of signal transduction with two major emphases: (A) genetically-defined signaling pathways regulating mammalian brain development and (B) core signaling pathways regulating cell proliferation, growth and survival. In addition to biochemical and cell biological approaches, we employ mass spectrometry-based proteomics as a primary tool to simultaneously monitor hundreds to thousands of proteins, their modifications and their interactions with other proteins following acute signal administration or across developmental stages.
A second focus of our work involves developing and applying proteomic methodology to advance diverse lines of biological inquiry, some of which have had little to no interface with proteomics. This makes these projects both exciting and challenging. These collaborative projects range from the identification of novel human blood group antigens; to the identification of host proteins that interact with arenavirus proteins; to targeted proteomic characterizations of wasps, pitcher plant ecosystems, ants, fruit flies, unicellular ciliates and parasitic protozoa.
