My name is Marc N. Potenza, and much of my professional life has been dedicated to studying the neuroscience and psychology of addiction. I am a psychiatrist and researcher who has spent many years examining how addictive behaviors develop, how they affect the brain, and how clinicians can better treat individuals struggling with addiction-related disorders.
Throughout my career, I have worked in academic medicine, clinical psychiatry, and neuroscience research. Much of my work has been associated with Yale University School of Medicine, where I have collaborated with researchers, clinicians, and students who share an interest in understanding complex mental health conditions.
My research focuses on addiction broadly, including both substance use disorders and behavioral addictions, such as gambling disorder. These areas continue to evolve as scientists learn more about the neurological mechanisms that influence decision-making, reward processing, and impulse control.
In this article, I would like to share the story of my professional journey — from my early education and clinical training to my later work in addiction neuroscience and behavioral research.
Early Academic Interests
From early in my education, I was drawn to the study of biology and neuroscience. Understanding how the brain functions and how it shapes human behavior fascinated me. Questions about why people make certain decisions, how emotions influence actions, and how mental health conditions develop became central to my academic interests.
During my undergraduate studies I focused on scientific fields that examine the relationship between brain function and behavior. This academic background eventually led me toward medicine, where I believed I could combine scientific inquiry with clinical practice.
Medical education allowed me to explore many areas of healthcare, but psychiatry quickly stood out as the field where my interests felt most aligned. Psychiatry integrates neuroscience, psychology, and clinical medicine, offering an opportunity to study the brain while also helping patients navigate mental health challenges.
After completing medical school, I pursued specialized training in psychiatry, where I began to encounter patients dealing with addiction and impulse control disorders.
Clinical Training in Psychiatry
During my psychiatric training, I worked with individuals facing a wide variety of mental health conditions. Many of the patients I encountered struggled with substance use disorders, including alcohol dependence and drug addiction.
These experiences highlighted how addiction affects not only individuals but also families and communities. Addiction often involves complex interactions between biological vulnerability, environmental stressors, and behavioral patterns.
While substance addictions were already well recognized in psychiatric research, I also became interested in behavioral addictions — compulsive behaviors that activate the brain’s reward systems in ways similar to substances.
These behaviors can include:
- gambling disorder
- compulsive gaming
- internet-related behavioral addictions
- impulse control disorders
Understanding these patterns required exploring how the brain processes reward, risk, and decision-making.
Beginning My Research Career
As my clinical training progressed, I became increasingly interested in research. Clinical experience raised many questions about why addiction develops and how treatment approaches might improve.
Research offered an opportunity to explore these questions using scientific methods.
One of the key approaches in addiction neuroscience involves studying brain activity during decision-making tasks. Researchers often use neuroimaging techniques such as functional MRI to observe how different brain regions respond when individuals evaluate risk, reward, and uncertainty.
These studies can reveal patterns of brain activity that differ between individuals with addiction disorders and those without such conditions.
My research interests gradually expanded to include:
- neurobiology of addiction
- impulse control disorders
- decision-making and risk evaluation
- behavioral addictions such as gambling disorder
These topics remain central to my work today.
My Work at Yale University
Much of my professional career has been connected with Yale University School of Medicine, where I have participated in research, teaching, and clinical work.
Academic institutions provide unique opportunities to collaborate with experts from multiple disciplines, including neuroscience, psychology, public health, and psychiatry.
At Yale, I have been involved in research programs examining addiction and behavioral health. These programs often involve interdisciplinary teams working together to study complex psychiatric conditions.
Academic responsibilities typically include several different activities:
- conducting research studies
- publishing scientific papers
- teaching medical students and psychiatric residents
- supervising graduate researchers
- presenting research findings at conferences
Working within an academic environment allows research findings to inform clinical practice and public health discussions.
My Research on Gambling Disorder
One of the areas I have spent considerable time studying is gambling disorder.
Gambling disorder is recognized as a behavioral addiction and is included in psychiatric diagnostic systems. It involves persistent gambling behavior that leads to distress, financial difficulties, and disruption of personal life.
When I began researching this area, behavioral addictions were still emerging as an important field within psychiatry. Many researchers were primarily focused on substance-related addictions.
However, evidence began to show that behavioral addictions share several important features with substance addictions. Both involve changes in brain circuits related to reward processing, impulse control, and emotional regulation.
My research has explored how brain regions associated with reward and motivation respond in individuals with gambling disorder.
Neuroimaging studies suggest that these neural systems may function differently in people experiencing addictive behaviors.
Understanding these mechanisms can help inform treatment strategies and improve support systems for individuals affected by behavioral addiction.
Publications and Scientific Contributions
Over the course of my career, I have contributed to numerous scientific publications related to addiction neuroscience and psychiatry.
Scientific publishing is a crucial component of academic research because it allows discoveries to be shared with the global scientific community.
Research findings are evaluated through peer review and published in academic journals, where other researchers can analyze, replicate, and build upon the work.

Teaching and Mentorship
Teaching has been an important part of my academic career. Training future psychiatrists and researchers allows knowledge to continue developing within the field of mental health.
Medical education involves guiding students and trainees as they learn about psychiatric disorders, clinical care, and scientific research.
Working with young researchers and clinicians is particularly rewarding because it helps ensure that new perspectives and ideas continue advancing the field.
My career has focused on understanding addiction from multiple perspectives — clinical, psychological, and neurological.
Addiction remains one of the most complex challenges in mental health. Continued research is essential for improving treatment approaches and expanding public understanding of addictive behaviors.
By combining clinical practice with scientific investigation, I hope that my work contributes to the broader effort to better understand addiction and support individuals affected by it.
