Professional Interest/Expertise/Specializations:
The major goal of my laboratory is to elucidate the cellular and molecular mechanisms that control wound healing and pathologic contractures. The unifying feature of these studies is to understand the interplay between actin isoforms, actin dynamics, and the mechanical environment in regulating myofibroblast formation and function. Current studies examine the role of different actin isoforms in contractile force generation and how mechanical forces regulate gene expression of cytoskeletal proteins through actin dynamics and the myocardin related transcription factors. These studies involve transgenic and knockout mouse models, in vitro models to measure and regulate force generation, and molecular techniques to study gene regulation.
