About Us

Drawing on expertise in big data analytics, genomics, neuroscience, precision medicine and clinical trials, the Massachusetts General Hospital Department of Psychiatry is uniquely positioned to lead the rapidly emerging field of precision psychiatry. To drive this transformation, we created the Center for Precision Psychiatry, an interdisciplinary center integrating research, clinical implementation, education and training, advancing risk prediction and prevention of mental health outcomes, including suicide prevention.


The mission of the Center for Precision Psychiatry is to integrate research and clinical practice to enable more accurate risk prediction, targeted prevention, precise diagnosis and effective treatments for psychiatric disorders.

A major focus of the Center is a deep investment in addressing suicide, including the prediction and prevention of suicidal behaviors and the care of patients across all areas of medicine who are affected by this growing public health crisis.

What is Precision Psychiatry?

The field of psychiatry is at a singular moment of challenge and opportunity. There is an increasing recognition that neuropsychiatric disorders affect all walks of life and are responsible for an enormous burden of suffering, disability and even mortality. We recognize that early intervention can improve prognosis, but we have few tools for identifying risk or preventing illness. We have treatments that help many people, but for others prove ineffective. Existing treatments lack precision, rooted in insights that are decades old and based on what works for the average person.

Fortunately, we now have powerful new opportunities to overcome these challenges, the emergence of a new framework for improving health and treating disease: precision medicine.

Advances in genetics and neuroscience give us the tools to develop novel therapies, while big data resources and machine learning help identify those at risk and facilitate more effective prevention or early intervention.

The idea behind precision medicine is to move beyond a one-size-fits-all approach by accounting for our individual differences in biology, environment and lifestyle to develop more targeted and effective approaches to diagnosis, treatment and prevention. We have already seen major dividends from precision medicine, including the development of targeted treatments for cancer and heart disease, and new methods for predicting individual risk of these and other diseases. We now have an opportunity to bring precision medicine to psychiatry and to lead a transformation of the field toward a new paradigm of precision psychiatry.

Fundamental unsolved questions remain in our ability to prevent, diagnose and treat mental illness, including:

  • How do genes, environment and lifestyle contribute to vulnerability and resilience?
  • How can we predict and prevent suicide?
  • Can we predict who will develop posttraumatic stress disorder after trauma so that we can enable targeted prevention?
  • Can we use genomics and other biomarkers to improve diagnosis?
  • How can we identify undiagnosed psychosis to improve outcomes?
  • Which antidepressant will work for which patient?
  • How can we move beyond a one-size-fits all, trial-and-error approach to treatment?

Strategic Pillars

The Center's work will be focused in four strategic areas:

Precision Prevention

  • Use data-driven approaches, develop and implement strategies to enable risk prediction and preventive interventions for important mental health outcomes
  • Leverage big data resources (i.e., electronic health records, genomic risk scores and mobile health technologies) along with machine learning and artificial intelligence to predict individual risk of important outcomes including suicide, post-traumatic stress disorder (PTSD) after traumatic exposures, first episode psychosis
  • Implement risk, prevention and treatment algorithms as clinical decision support tools for clinical practice at the point-of-care
  • Develop a specialized clinical and consultation service to implement suicide prevention efforts and support clinicians across Mass General in the management of patients at risk of self-harm
  • Establish a “learning health system” approach in which real-world outcomes are captured, analyzed and applied to create a feedback cycle for learning and improvement of care

Precision Treatment Optimization

  • Reduce trial-and-error prescriptions by using data-driven methods to more rapidly match individual patients to the most effective treatment, including medication, psychotherapy and digital health technologies
  • Leverage large-scale health system data, pharmacogenetics and artificial intelligence to develop clinically useful tools to stratify patients and match them to treatments that are most likely to provide benefit
  • Validate tools in controlled trials and disseminate them to clinical practice using a learning health system approach

Precision Neuroscience and Novel Therapeutics

  • Develop new, more effective treatments based on our understanding of the causes of disease
  • Leverage large-scale genomic studies to identify the genetic basis of psychiatric disorders
  • Use state-of-the art tools--including functional genomics and stem cell biology--to identify useful biomarkers and uncover mechanisms linking genes to disease

Education, Training, Dissemination

  • First Annual Conference on Precision Psychiatry to convene experts and showcase cutting-edge research – September 30, 2021- October 1, 2021 (Virtual)
  • Regular Precision Psychiatry Seminar for trainees, faculty and staff across the Mass General Department of Psychiatry (begins 2021)
  • Annual Mass General Grand Rounds Lecture in the area of suicide (begins 2021)
  • Training programs for future research scientists and clinicians in the methods, tools and clinical practice of precision psychiatry
  • Educational materials (e.g. webinars, podcasts and didactic modules) with a focus on enhancing risk assessment and management of patients at risk for suicide
