Reasearcher Bio
My main area of interest are attentional functions and their pharmacological modulation, both in the normal organism and in chronic disease states characterized by attentional dysfunction. My research has focussed on nicotine as a cognitive enhancer. During my Ph.D. at King's College London, I investigated neuronal mechanisms of nicotine-induced attentional enhancement in rat models of attention. During my postdoctoral fellowship at the National Institute on Drug Abuse, I investigated neuroanatomical substrates of the effects of nicotine on specific attentional functions in humans using fMRI techniques. Currently, I am a junior faculty at the Maryland Psychiatric Research Center, where I am focussing on attentional deficits in schizophrenia. My aim is to characterize effects of nicotine on attentional functions in schizophrenia using behavioral and neuroimaging techniques.
