Professional Interests

 

I am an Assistant Professor at the New York Institute of Technology College of Osteopathic Medicine, Director of the NYIT Imaging Center, and the Group Leader for Imaging, Visualization, and Modelling within the recently formed Center for Biomedical Innovation at NYIT-COM and a Visiting Assistant Professor in the Dominick P. Purpura Department of Neuroscience At Albert Einstein College of Medicine. My research is in the area of cellular neuroscience and gap junctions.

I performed my PhD thesis research with Vladimir Parpura at the University of Alabama, Birmingham where I combined genetically encoded calcium sensors with glial promoter constructs and adapted a nematode primary cell culture technique to perform some of the first studies of Caenorhabditis elegans glia. I received my PhD in 2011 in Neurobiology at UAB. My postdoctoral training was at Albert Einstein College of Medicine with David C. Spray. There, I used live-cell high-resolution laser scanning confocal microscopy and super-resolution microscopy to reveal novel and fundamental aspects of the gap junction plaque structure and anatomy of other supramolecular cellular assemblies. I recently used quantitative high-resolution microscopy to show that the structure-characteristics of gap junction connections are modifiable and dependent on specific residues in the cytoplasmic carboxyl-terminus of the gap junction proteins (connexins) with follow-up research continuing on that topic in my own lab.

Upon establishing an independent laboratory at the NYITCOM in May, 2017, I’ve included both undergraduate and medical students in research projects on cell biology using microscopy and which bring together disease conditions of the heart and brain. I’ve served as a mentor and/or assistant advisor for more than 15 students ranging across experience levels from high school, to undergraduates, graduate students, postdocs and medical residents. My research at NYIT focuses on intercellular communication through gap junctions and the effects that such communication has on nuclear hormone receptor signaling and cellular metabolism in the context of human neural disease models.
