Research

I joined the laboratory of Dr. Edwin Chapman following completion of my doctoral dissertation at IU.  I am currently working on several diverse research projects related to neurotransmission and vesicular release.  Our laboratory is principally interested in the synaptotagmin family of calcium sensing proteins and their role in stimulated secretion.  I have identified a novel synaptotagmin interacting protein and am currently characterizing the potential effects this interaction has on neuropeptide and neurotransmitter release.  Another project that I am integrally involved in is answering whether botulinum neurotoxins can travel neuron to neuron and hence inhibit neurons distal to the site of initial uptake.
