Research Interests:

My laboratory is interested in studying the mechanisms regulating cytoskeletal dynamics in neurons with a focus on regulation of myosins and microtubules.    

Our goal is to understand how myosin and microtubule dynamics influence normal and diseased brain functions.   Our laboratory was the first to discover a role for the myosin co-chaperone UNC-45A during myposin II-assisted cytokinesis in mammalian cells.  Since then, we have discovered that UNC-45A is required for additional cytoskeletal-associated functions, including intracellular transport and neurite outgrowth.  

Because we believe that successful collaborations are at the core of scientific discovery, we have partnered with scientists and researchers across the University, and other national and international institutions.  For our studies, we, along with our partners, utilize innovative techniques, including Atomic Force Microscopy (AFM), TIRF Microscopy, HPLC, and FPLC techniques to investigate how UNC-45A regulated myosin and microtubule dynamics in vitro and in vivo.  

Our laboratory welcomes energetic students, capable of thinking outside the box, and willing to make important contributions to scientific discovery.  Students in the laboratory are encouraged to write their own grants, papers, and to become independent investigators early on in the process.  Our students are known to have multiple first author publications and be recipients of grant awards.
