Picture of 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 purposes 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 (Dr. Elena Shumay). We evaluate the disruption of these interactions in addiction, morbid obesity (Dr. Gene-Jack Wang) 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 (Dr. Sunny Kim), which is focused on the development of ligands to map epigenetic processes, development of analytical tools (Dr. Dardo Tomasi) to help analyze and understand the underlying physiology behind the dynamically complex patterns of brain networks.

Sung Won (Sunny) Kim, PhD
Staff Scientist
Voice: 1 (301) 496-5548

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.

Staff Scientist
Voice: 1 (301) 402-5861

Elena is conducting genetic research in LNI group. She is interested in identifying genetic-and epigenetic polymorphisms that can explain individual differences in brain imaging phenotype. Along with analysis of the accepted genetic markers, she is interested in discovering new polymorphisms in the known candidate genes as well as in exploring previously unspecified genetic targets and assessing them as putative biomarkers.

Dardo Tomasi, PhD
Staff Scientist
Voice: 1 (301) 496-1589

Dardo is MRI physicist with expertise in gradient coil design, functional MRI and PET imaging. His work focuses on brain metabolism, function, structure and neurochemistry in normal subjects and psychiatric populations. He is interested on novel MRI approaches to map brain function and connectivity with high temporal and spatial resolution. Recently, Dr. Tomasi developed ultra-fast graph theory methods to compute short- and long-range functional connectivity maps from "resting-state" echo-planar imaging time series that when used in large public image databases revealed pronounced gender and aging effects on the brain's functional architecture.

Senior Clinician & Clinical Director
Voice: 1-301-496-5012

Gene-Jack is a board certified Nuclear Medicine physician. He joined NIAAA as a senior clinician and the clinical director of LNI in 2013. Prior to his current appointment, he was a professor of Radiology at Stony Brook University, a senior scientist and chairman of medical department at Brookhaven National Laboratory and held a joint appointment as a professor of Psychiatry at Mount Sinai School of Medicine. His research focuses on the application of PET and functional MRI to the study of various brain disorders. He is interested in using PET to study the neuro-psychiatric mechanisms and manifestations of alcoholism, drug addiction, ADHD, obesity and eating disorder in humans. Using PET, he first reported similarity of human brain circuits’ disruption in drug addiction and in obesity.

Samantha has been a postdoctoral fellow with LNI since September of 2014. She earned a BS in biomechanical engineering from Stanford University and a PhD in biomedical engineering from the University of Southern California. Samantha’s doctoral research explored cross-modal plasticity and connectivity changes in blind patients receiving a retinal prosthesis. As such, her background encompasses a mixture of neuroimaging (fMRI and DTI), electrical engineering, vision science, computational science, and device design. Her current work explores the structural connectivity of cortical networks affected by addiction, as well as the interaction of the visual system with resting-state networks in alcoholics and drug abusers.
