J. Aaron Johnson, PHD

Director of Institute of Public and Preventive Health

Professor - Department of Psychological Sciences, School of Graduate Studies

Dr. Johnson’s research is focused on the implementation of evidence-based practices in substance abuse prevention and treatment. He has worked with populations in addiction treatment facilities; medical settings including primary care, emergency department, trauma unit, and urgent care; as well as with justice-involved populations (jails, prisons, transitional centers, drug courts, probation/parole). In is recent work, he has incorporated technology as a means of enacting behavior change within this field. In addition to intervention-based research, Dr. Johnson has published several validation studies of brief alcohol and/or drug screening tools for use in general medical settings, as well as a number of publications related to training health professionals to conduct alcohol/drug screening and brief intervention. Dr. Johnson’s work has been continuously funded for more than two decades with federal grants from the Substance Abuse and Mental Health Services Administration, National Institute on Drug Abuse, National Institute on Alcohol Abuse and Alcoholism, and the National Library of Medicine and from private foundations including the Robert Wood Johnson Foundation, and Healthcare Georgia Foundation.

Biplab Datta, PHD

Assistant Professor of Institute of Public and Preventive Health

Assistant Professor - Department of Population Health Sciences, Hull College of Business

Dr. Datta’s research explores the niche areas in the junction of public health and economics. His works broadly cover the socioeconomic, demographic, and behavioral determinants and risk factors of non-communicable diseases (NCDs); the socioeconomic burden of NCD health conditions and associated treatment costs; access and affordability of NCD related healthcare; and health system preparedness for managing NCDs. He has particular interest in investigating the impacts of certain disease conditions on individual/household’s economic decision making. His research generates evidence on how NCD treatment costs are associated with household resource allocation, consumption displacements, poverty and impoverishment. His works also examine disparities in health risks such as tobacco-use and heterogeneous impact of health policies across socioeconomic groups. He has a special interest in investigating the role of psychosocial factors such as household environment and life course events such as adolescent childbearing in hypertension and other disease outcomes. The far reaching goals of his research are to facilitate strategic interventions for NCD prevention and control, and strengthening the health systems for effective management of both infectious and non-infectious diseases.

 Research Interest: Health Economics, Global Health, Non-communicable Diseases, Healthcare Financing, Health Disparity, Tobacco Control

Paul Seale, MD

Professor of Institute of Public and Preventive Health

Professor - Department of Psychiatry and Health Behavior MCG

A graduate of the University of Texas (Austin) and Baylor College of Medicine, Dr. Seale is a clinician researcher with board certification in Family Medicine and Addiction Medicine. Since completing an NIAAA-NIDA sponsored faculty development fellowship in 1987-1988, he has been involved in practice, teaching and research related to substance use screening, brief intervention, and referral for treatment (SBIRT) for more almost three decades in both the U.S. and abroad. Recent interprofessional SBIRT training grants in collaboration with Johns Hopkins University, Mercer University, Augusta University and U. of Georgia have trained more than 1,500 primary care providers including 1,000+ advanced practice nursing students, 100+ nursing faculty & preceptors, and dozens of physician assistants. With over 14 years’ experience in office-based opioid treatment (OBOT) practice, training, dissemination and mentoring, he has a special interest in bridges and barriers to treatment of opioid use disorder and is principal investigator of a pilot study of opioid use disorder in older adults. His involvement for more than a decade in full-time global health in Asia and the Americas led to the development of resilience and recovery training programs taught through storytelling which have been translated into seven different languages and are now being used with indigenous and other vulnerable populations across Latin America and Africa. He has served as author or co-author of more than 70 peer-reviewed journal articles. Dr. Seale’s research has been funded with federal grants from the Substance Abuse and Mental Health Services Administration, National Institute on Alcohol Abuse and Alcoholism, National Institute on Drug Abuse, National Institute of Diabetes and Digestive and Kidney Diseases and the Centers for Disease Control and from private foundations including the Betty Ford Foundation, the Conrad Hilton Foundation and the John Templeton Foundation.

 Research Interest: improving and disseminating the use of storytelling approaches for resilience and recovery training, recognition and treatment of opioid use disorder in older adults, substance use screening, and improving delivery of SBIRT and Medications for Addiction Treatment (MAT) in rural and underserved areas.

Dr. Vitacco is a board-certified forensic psychologist whose research focuses on best practices in the broad area of psychology and the law. Specifically, his research has focused on the treatment and prevention of violence among individuals found not criminally responsible and returned to the community (i.e., conditional release), evaluating how forensic psychologists can appropriately utilize social media information in their forensic practice, detecting atypical response styles (e.g., malingering) in forensic evaluations, legal applications of psychopathy, and evaluating and treating violence potential with individuals housed in forensic inpatient hospitals. Dr. Vitacco has extensive experience working with justice-involved individuals, especially those adjudicated not competent to proceed to trial or not criminal responsible because of mental illness. He has also worked with individuals on probation/parole and individuals who have been civilly committed. As part of his work on conditional release, Dr. Vitacco has partnered with multiple states to evaluate conditional release effectiveness with individuals with serious and persistent mental illness. He has also researched psychopathy and its correlates, including stress reactivity, with juveniles placed in detention facilities.
