Research Interests

My major area of interest is cell communication – how cells receive signals and decipher them to respond in an appropriate fashion.  I am particularly interested in communication in neuronal cells – both central and peripheral.  My current programs, based on this work, include:

  1. Signaling in neurodegenerative diseases:  I am using Alzheimer’s disease as a model to understand the signaling events that occur during neuronal degeneration. 
  2. Signaling in biological clocks:  I am studying the signaling molecules in defining the circadian rhythm in mammals using rat and mouse as model systems. 
  3. Signaling in Fascia:  I am studying the role of calcium signaling in the fascia .
  4. Retinal signaling:  I am investigating the role of membrane guanylate cyclases and NCS proteins in non-photoreceptor signaling in the retina
