Personal info

I finished working on my doctoral thesis on the non-image forming (NIF) effects of light in humans at the Department of Chronobiology, INSERM U846, Lyon, France. My thesis was done done under the supervision of Howard M. Cooper with a title of "Spectral modulation of melanopsin responses: Role of melanopsin bistability in pupillary light reflex". Now I am in the process of looking for a postdoctoral position.

Interests

Student at École Doctorale Neurosciences et Cognition (NSCo), and conducted the research for the dissertation at the Department of Chronobiology (INSERM U846) under the supervision of Howard M. Cooper (HDR). Thesis project was titled: "Spectral modulation of melanopsin responses: Role of melanopsin bistability". Thesis was defended 02 March 2012 at Université Claude Bernard, Lyon 1, France.
