The PET Program consists of 21 Core Faculty and 25 Affiliate Faculty. Each of the faculty are aligned with one of the two Concentrations, Etiology of Mental Disorders and Interventions in Mental Disorders. In addition, the Data-Intensive Methods Support Hub consists of 10 Affiliate Faculty with expertise in genomics, informatics and imaging. Many of the faculty in the two Concentrations have expertise in both, but we associate them here with the one they most strongly align. All Core Faculty are either in the Johns Hopkins Bloomberg School of Public Health and/or the School of Medicine.
The designation as “Core” means the faculty member can serve as a primary advisor for trainees over extended periods of time, such as for a dissertation. By contrast, Affiliate Faculty provide information and advice about developments or programs which may be of benefit to trainees, as well as temporary educational experiences, linkages and consultations, and access to data. Affiliate Faculty do not serve as primary mentors, but they frequently serve on Thesis Advisory Committees and as secondary mentors to trainees.
Etiology of Mental Disorders
This concentration provides advanced training in the principles and methods of psychiatric epidemiology to search for genetic and environmental causes of mental disorders. Surprisingly little is known about the causes of most mental disorders, and this has hampered our ability to develop more effective intervention strategies. The goal of this concentration is to train the next generation of scientists to carry out etiologic research that will advance our understanding of the causal mechanisms in mental disorders and lead to the identification of disease predictors that lay the foundation for developing more rational and effective strategies for prevention and/or treatment.

Interventions in Mental Disorders
This concentration provides advanced training in the principles and methods of psychiatric epidemiology that deal with developing and testing treatment and/or preventive interventions for mental disorders. Despite many years of research, the burden of mental disorders in the population has not abated. There is a need for new and more effective interventions to reduce the burden of mental disorders that plague public health. The goal of this concentration is to produce a new generation of researchers with the knowledge and skills to translate findings on the etiology of mental disorders into novel interventions, as well as to test the efficacy and effectiveness of these interventions to establish the evidence-base for their dissemination into standard practice.
