Picture of Dr. Nora Volkow

Dr. Volkow became Director of the National Institute on Drug Abuse (NIDA) at the National Institutes of Health in May 2003. In addition to her role in NIDA, she is the chief of LNI in NIAAA. Her work has been instrumental in demonstrating that drug addiction is a disease of the human brain. As a research psychiatrist and scientist, Dr. Volkow pioneered the use of brain imaging to investigate the toxic effects and addictive properties of abusable drugs. Her studies have documented changes in the dopamine system affecting, among others, the functions of frontal brain regions involved with motivation, drive, and pleasure in addiction. She has also made important contributions to the neurobiology of obesity, ADHD, and aging. Dr. Volkow has published more than 580 peer-reviewed articles and written more than 90 book chapters and non-peer reviewed manuscripts, and has also edited three books on neuroimaging for mental and addictive disorders.

 

What we do

LNI uses brain imaging (PET and MRI) to study the neurocircuitry that underlies the rewarding effects of drugs of abuse and of natural reinforcers and their disruption in diseases of addiction and obesity. For this purpose, we study how reward circuits modulate executive function (self-control), interoception, and motivation in the normal human brain including an understanding of the role of brain dopamine signaling, functional brain network interactions and genetics. We evaluate the disruption of these interactions in substance use disorder, morbid obesity and ADHD, which are disorders characterized by deficits in self-control and reward sensitivity. We also focus on methodological studies to advance the tools to study function of the human brain including development of PET radiotracers, which is focused on the development of ligands to map epigenetic processes, development of analytical tools to help analyze and understand the underlying physiology behind the dynamically complex patterns of brain networks.

E-mail: kims8@mail.nih.gov

Sunny is an organic chemist as well as chief radiochemist of LNI. His research focus has been on radiotracer development and its medical application using positron emission tomography (PET). His research involves the following: 1) design or selection of suitable molecules for radiotracer guided by in vitro biological activity, 2) organic synthesis and radiochemistry for in vivo imaging, and 3) optimization of radiotracers using rodents and non-human primates for translational research to humans. Recently, he completed the in vivo pharmacological profiling of buspirone using multiple dopamine tracers, to evaluate its potential for the treatment of cocaine addiction using a D3R-prefering radiotracer called[11C]PHNO. Since 2009, he continues his effort for in vivo imaging tool development targeting brain epigenetic biomarkers such as histone deacetylase (HDAC). Currently, he is also interested in automation and miniaturization of radiosynthesis devices for carbon-11 precursors and compounds, to optimize radiotracer production and streamline laboratory operations.
