Eric J. Nestler, MD, PhD, a globally recognized authority on the neurobiological foundations of addiction and depression, has recently been honored with election to the prestigious National Academy of Sciences (NAS). His induction into NAS marks a significant milestone in a career defined by groundbreaking research elucidating the complex molecular and cellular mechanisms that govern brain function in psychiatric disorders. As the Nash Family Professor of Neuroscience, Interim Dean for the Icahn School of Medicine at Mount Sinai, and Chief Scientific Officer for the Mount Sinai Health System, Dr. Nestler’s contributions are shaping the future of neuroscience and translational medicine.
Dr. Nestler’s scientific journey is characterized by pioneering methodologies that have redefined our understanding of brain adaptations in response to chronic stress and substance abuse. His laboratory has been at the forefront of utilizing viral-mediated gene transfer techniques coupled with inducible genetically engineered mouse models. These innovations allowed unprecedented manipulation of discrete neural circuits within the brain’s reward system, enabling causal investigations into how gene activity modulates behavior. This approach has provided vital mechanistic insights linking molecular changes with the characteristic behavioral phenotypes of addiction, such as compulsive drug seeking and relapse vulnerability.
Beyond dissecting addiction pathways, Dr. Nestler’s research unveiled shared molecular pathways underpinning diverse addiction modalities. His work revealed that common neurobiological mechanisms could govern seemingly distinct addictions, providing a unifying framework for understanding the neuroplasticity involved. Additionally, his laboratory developed one of the most robust mouse models for studying depression and related stress disorders, facilitating exploration of the critical role that reward-related brain circuits play in mood regulation. This animal model has since found resonance in human studies, confirming the translational validity of his findings and paving the way for potential novel therapeutic strategies.
The scope of Dr. Nestler’s research extends to epigenetics, where his team’s gene and chromatin analyses identified key proteins that mediate either susceptibility or resilience to chronic stress exposures. These discoveries have profound implications for psychiatry, as they suggest molecular targets for innovative treatments designed to fortify resilience or reverse maladaptive changes associated with depression and addiction. His work continues to inspire a paradigm shift, emphasizing the plasticity of neural circuits as a foundation for mental health interventions.
Since assuming leadership roles at Mount Sinai in 2016, Dr. Nestler has guided the Icahn School of Medicine’s academic and scientific agenda, advancing institutional research capabilities. As Interim Dean, his strategic focus encompasses fostering interdisciplinary collaborations and translating laboratory discoveries into clinical innovations. Under his stewardship, The Friedman Brain Institute has attracted top-tier scientists worldwide, positioning Mount Sinai as a powerhouse in neuropsychiatric research, with a dynamic emphasis on bridging fundamental neuroscience with patient-centered care.
Before joining Mount Sinai in 2008, Dr. Nestler made impactful contributions at UT Southwestern Medical Center as Chair of Psychiatry and at Yale University as Director of Molecular Psychiatry. His extensive publication record — exceeding 750 articles and five authoritative texts — reflects a career devoted to unraveling the intricacies of brain function and dysfunction. His scholarly influence has been recognized through numerous awards, including the Wilbur Cross Distinguished Alumnus Medal from Yale and the Peter Seeburg Prize in Integrative Neuroscience from the Society for Neuroscience.
Dr. Nestler’s experimental work has significantly advanced the field’s comprehension of how chronic drug exposure induces persistent changes in gene expression within reward-related brain regions such as the nucleus accumbens and ventral tegmental area. By selectively modulating transcription factors and epigenetic regulators, his lab demonstrated that these molecular alterations contribute to long-lasting modifications in synaptic connectivity and neuronal excitability, which manifest behaviorally as drug craving and relapse. These findings underscore the potential of targeting epigenetic mechanisms for developing novel pharmacotherapies.
The translational impact of his research is evident in his laboratory’s exploration of stress-induced plasticity, where they identified molecular signaling pathways mediating vulnerability or resistance to depressive-like behaviors in animal models. These insights inform clinical strategies aiming to identify biomarkers of susceptibility and tailor interventions accordingly. Moreover, the Nestler Laboratory’s work on chromatin remodeling highlights the dynamic nature of the epigenome as both a mediator and potential therapeutic target in neuropsychiatric disorders.
Mount Sinai’s election of Dr. Nestler to the NAS reflects not only his individual achievements but also the institution’s broader commitment to advancing neuroscience. Within the Mount Sinai faculty, six members, including Dr. Nestler, hold NAS memberships, underscoring the system’s prominence in scientific research. This collective expertise contributes to Mount Sinai’s reputation as an epicenter for innovative brain science, integrating basic research with clinical application to address some of the most intractable neurological and psychiatric diseases.
The recognition by leading Mount Sinai leadership captures the transformative role Dr. Nestler plays both scientifically and administratively. Brendan G. Carr, MD, CEO of Mount Sinai Health System, emphasized Dr. Nestler’s stature as a world-class neuroscientist whose research has the potential to impact millions suffering from brain disorders. Dennis S. Charney, Dean Emeritus of the Icahn School of Medicine, praised Dr. Nestler’s visionary leadership in shaping the next chapter of Mount Sinai’s neuroscience enterprise, built on a foundation of translational research and clinical excellence.
Mount Sinai Health System itself is a comprehensive academic medical entity comprising hospitals, outpatient practices, multiple research centers, and educational institutions. It harnesses cutting-edge technologies such as artificial intelligence and informatics to enhance patient care while advancing scientific discovery. This integrated approach ensures that discoveries from laboratories like Dr. Nestler’s are efficiently translated into innovative therapies, shaping the future of personalized neurological and psychiatric care on a global scale.
As Dr. Nestler steps into his role as Interim Dean of the Icahn School of Medicine following Dr. Charney’s retirement, his trajectory highlights a seamless transition of visionary scientific leadership committed to rigorous inquiry and clinical translation. His multifaceted expertise, ranging from molecular neurobiology to institutional stewardship, marks him as a pioneering figure in contemporary neuroscience. The field eagerly anticipates the continued impact of his work, which merges fundamental science with transformative potential for improving human mental health.
