Dr. Cwik has conducted research in suicide, substance use and trauma, focusing on preventing Native American mental health disparities for the past 10 years. Dr. Cwik’s research, in collaboration with the White Mountain Apache Tribe, has helped to identify unique risk factors impacting these disparities, the importance of protective factors including cultural identity, and promising interventions associated with a reduction in the Apache suicide rate. Mary has expertise in community academic partnerships, developing mental health interventions for different cultural contexts, training community mental health specialists, screening, surveillance (Apache model recognized by SAMHSA, Indian Health Service/IHS and the Academy of Child and Adolescent Psychiatry), mixed methods designs, RCTs, and Emergency Department settings.

Zach Kaminsky

Zachary Kaminsky, PhD is an Assistant Professor of Psychiatry and Behavioral Sciences at the Johns Hopkins University School of Medicine. His laboratory studies animal models of psychiatric conditions side by side with human populations in attempts to better understand the molecular epigenetic underpinnings of psychiatric phenotypes and to enable the generation of true “bench to bedside” translational findings. A specific focus of the lab is the development of disease predictive biomarkers utilizing DNA methylation marks in peripheral tissues to diagnose the risk to a future mental illness. New directions involve the pairing of peripheral epigenetic biomarkers with prospective neuroimaging studies. We are actively studying epigenetic marks in relation to suicide and postpartum depression.


Paul Nestadt

Paul S. Nestadt, MD is a postdoctoral fellow in the Psychiatric Epidemiology program in the Johns Hopkins Bloomberg School of Public Health and serves as supervising psychiatrist for the Anxiety Clinic in the Johns Hopkins School of Medicine. He is board certified in psychiatry and has focused his research on suicidality. He has developed expertise in data analysis and mental health research methodologies while investigating strategies for suicide risk stratification. He has written on the relationship between stress and mental health, largely targeting non-psychiatrists within the medical field through textbook chapters, lectures, and the co-creation and continuing editorship of the Johns Hopkins Psychiatry Guide, a top-selling manual and smartphone app for non-psychiatrists. His most recent work compares differential vulnerabilities to suicide in urban and rural populations, and the role of firearms and alcohol access.​​

Holly C. Wilcox, PhD is an Associate Professor in the Johns Hopkins Bloomberg School of Public Health Department of Mental Health and the School of Medicine Department of Psychiatry.  Dr. Wilcox has spent the past 25 years actively engaged in suicide prevention research in schools, universities, emergency departments, and other settings.  Dr. Wilcox’s most significant contributions have been in three areas: 1) large population-based, prospective cohort studies of youth suicidal behaviors; 2) the evaluation of impact of community-based universal prevention programs targeting youth suicidal behaviors; and 3) the identification of biomarkers to inform suicide prevention.    Dr. Wilcox led a national project to identify research needs for data linkage and analyses of linked data to serve as the foundation for a National Institutes of Health Pathway to Prevention workshop on suicide prevention. She is the co-chair of the Suicide Prevention Task Group of the National Network of Depression Centers, a non-profit 501(c)(3) network of 23 leading academic medical centers.  She has offered since 2005 a course at Johns Hopkins entitled Suicide as a Public Health Problem.
