Dr. Parikh received his doctoral degree in Life Sciences/Pharmacology from Punjabi University in 1999. After serving as a Research Scientist in the Drug Discovery Group at Sun Pharmaceutical Industries Ltd. for two years, he joined the Medical College of Georgia as a postdoctoral fellow to obtain training in Neurochemistry and Neuropsychopharmacology. He integrated perspectives of systems and behavioral/cognitive neuroscience into his research by acquiring further postdoctoral training in Psychobiology and Neuroscience from the Ohio State University and the University of Michigan. Prior to joining Temple as Assistant Professor (tenure-track) in 2009, he held the position of Assistant Research Scientist in the Department of Psychology (Biopsychology Program) at the University of Michigan.

Dr. Parikh’s primary research focuses on the neurochemistry of cognition with special emphasis on attention and executive functions. He is interested in understanding how neurochemical signaling systems, specifically the neurotransmitters and trophic factors, process information in discrete brain circuits to support vigilance, attentional switching, working memory, flexible decision-making and cognitive control of behavior. Additionally, he studies cognitive aging and mechanisms regulating the cognitive reserve capacity. As cognitive impairments represent an important attribute of major neuropsychiatric disorders and age-related neurodegenerative disorders such as schizophrenia, drug addiction and Alzheimer’s disease, Dr. Parikh’s research has major implications for understanding the neurochemical basis of attentional and executive deficits associated with these pathologies. The long term goal of his research is to identify potential biomarkers to develop psychotherapeu tic approaches for the treatment of brain disorders with dysfunctional cognitive abilities. Dr. Parikh utilizes an integrative multidisciplinary approach to understand brain-behavioral relationships in both normal and pathological conditions. Some of the techniques routinely used in his lab are in vivo extracellular electrochemical recordings to monitor real time changes in synaptic transmission, operant paradigms to assess cognitive functions in rodents, and genetic and biochemical approaches including the use of transgenic mice and vector-based RNAi methods, immunohistochemistry, cell imaging, western blotting and PCR. Dr. Parikh’s research is published in many high impact neuroscience journals and is funded by the National Institute of Health, Brain and Behavior Research Foundation and the American Federation for Aging Research.
