Research Interests:

My research focus is on the physiological mechanisms that govern photoreception in the marine environment. Specifically, my interests lie in vertebrate retinal neurobiology and dermal light-sensing systems, and the evolution of these systems in the context of the surrounding light environment. My approaches include various histological and microscopical techniques, electrophysiology, and analyses of gene expression.
