Research Summary

Have you ever wondered how your brain got wired? How a single neuron finds a unique signaling partner among over 10 billion other neurons? During
development neurons not only face this daunting task but often migrate extremely long distances (>50,000 cell diameter equivalents) to accomplish it.
My lab focuses on this problem and the specialized guidance device called the growth cone that provides the motility and signal transduction capabilities
needed for axon guidance. Current lab projects include: 1) Molecular motor and cytoskeletal protein dynamics underlying growth cone motility. 2) Cell surface receptors involved in target recognition. 3) Investigation of signal transduction pathways involved in controlling the cytoskeletal protein effectors involved. We address the relevant cell biological processes using a "molecular physiology"
approach. This typically entails generation of molecular probes to investigate dynamics of the process and/or protein-protein interactions in living neurons. We use a variety of high resolution imaging and biophysical approaches such as: multimode fluorescent speckle microscopy, laser trapping, photobleaching, and "caged" probe photoactivation.
