Office of the DNB Director

What We Do:

DNB supports basic and clinical biomedical and behavioral research to address the public health problem of drug use disorders and addiction by developing and supporting an extramural research program that provides an understanding of the neurobiological and behavioral mechanisms of addictive drugs and their consequences. The division has 6 main goals:

  • Goal 1: Identify drug targets and develop interventions to treat addiction and other adverse effects of drugs.
  • Goal 2: Identify the neural substrates underlying different cognitive dimensions of substance use disorder
  • Goal 3: Elucidate the neurobiological bases of individual differences in drug consequences from genes to molecules, cells and circuits
  • Goal 4: Identify behavioral processes that underlie drug use disorders and addiction.
  • Goal 5: Promote cross-cutting NIDA priorities in the areas of HIV, pain, sex differences, and training.
  • Goal 6: Develop and sustain a diverse workforce in substance use disorders research

The Office of the Director, directs, coordinates, and supports the Division’s mission & activities through:

  • Maintaining and evaluating our strategic directions and goals
  • Supporting our goals through our branch structure
  • Developing an leveraging collaborations and activities across NIDA and NIH

Staff Research Interests:

  • Valentino, Rita, Ph.D. - Director
    (301) 443-1887
    As the Director of DNB, Dr. Valentino, leads program staff to set a vision that advances the basic and clinical research mission of NIDA to elucidate the neurobiological underpinnings of substance use disorders from the molecular to behavioral level and to discover approaches for treating it. She bridges DBN with DTMC and DESPR by promoting translation from target discovery to drug development and by using epidemiology to inform research directions. She represents NIDA on trans-NIH initiatives including BRAIN, Neuroscience Blueprint and CCRWH. Her career spans 26 years of academic, research, and leadership experience in neuropsychopharmacology and stress neurobiology. She previously directed the Stress Neurobiology Division within the Department of Anesthesiology at The Children’s Hospital of Philadelphia, and was a Professor of Anesthesiology and Critical Care at the University of Pennsylvania School of Medicine, Philadelphia. Dr. Valentino is particularly recognized for her research on the neurobiology of stress, the impact of sex, age and coping style on behavioral and cognitive health, and how this can determine vulnerability to substance use. She is a Fellow of the American College of Neuropsychopharmacology and a Fellow of the American Society for Pharmacology and Experimental Therapeutics.

  • Christina Hatch, Ph.D. – Program Analyst
    (301) 827-4262
    DNB is pleased to welcome Dr. Christina Hatch, who was hired as a program analyst for DNB. Christina’s expertise is in the neural basis of processes related to decision-making, addiction, and Parkinson’s disease. Christina received a Ph.D. in Neural Science from NYU under the mentorship of Dr. Roozbeh Kiani. There, she studied perceptual decision-making and perceived confidence in humans and non-human primates using a combination of behavioral, neurophysiological, and computational approaches. Her research investigated the effect of prior probability and value information on choice and confidence and examined how these processes are instantiated across different brain areas. Prior to graduate school, Christina worked as a Research Associate in the Cellular Neurobiology Research Branch at the National Institute on Drug Abuse (NIDA), where she investigated the effects of chronic drug exposure on cortical activity using electrophysiological and optogenetic techniques in a rodent model of addiction. Prior to that, she was a Postbaccalaureate Fellow in the Neurophysiological Pharmacology Section at the National Institute of Neurological Disorders and Stroke (NINDS). There, she studied the relationship between dopamine loss and basal ganglia-thalamocortical system function using electrophysiological and pharmacological techniques in a rodent model of Parkinson’s disease. Christina holds bachelor’s degrees in Physiology and Neurobiology, Psychology, and Philosophy from the University of Maryland. She will initially be working with Dr. Susan Wright on Data Science programs and initiatives.
