Alison Athey, PhD

Alison received a PhD in Psychology at Case Western Reserve University. She completed a residency in clinical psychology at the Brown University Warren Alpert Medical School Clinical Psychology Training Consortium. Her research has focused on the role of cognition and learned behaviors in suicide risk, especially among individuals in marginalized and high-risk groups. Alison uses registry studies, psychological autopsy, and epi-/genetic approaches to evaluate changes in suicide risk within individuals and families. As a JHU PET postdoctoral fellow working with Drs. Holly Wilcox and Paul Nestadt, she hopes to extend this bench-to-bedside approach by learning public health tools and by evaluating potential areas of overlap between suicide and other life-threatening behaviors (e.g., opiate overdose).

Kristin Mignogna, PhD

Kristin Mignogna

Kristin Mignogna, PhD went to the University of Virginia for her undergraduate studies, majoring in Biology and Psychology, and minoring in Bioethics. From there, she continued on to the Institute for Psychiatric and Behavioral Genetics at Virginia Commonwealth University where she received her Ph.D. in Psychiatric & Statistical Genetics. Her dissertation research focused on genome-wide systems genetics of alcohol consumption and use disorder in both humans and genetically complex mice. She is now utilizing similar methodologies to examine genotype and gene expression levels in the context of mood disorders, as a JHU PET postdoctoral fellow working for Fernando Goes, M.D. Her overarching research goal is to gain insight into the etiology of psychiatric disorders, so that they may ultimately be pharmacologically treated in a more precise and personalized manner.
