Post-Doctoral Fellows

Jeffrey D. Knotts, Ph.D.

Dr. Knotts is a post-doctoral fellow in the Anxiety and Depression Research Center (ADRC). His research investigates the neural mechanisms associated with mental disorders such as anxiety, depression, and PTSD. He is particularly interested in using fMRI to study how the activity of threat and reward systems may be predictive of anxiety and depression symptoms in young adults. Dr. Knotts received his doctorate from the University of California, Los Angeles, where his work focused on optimizing psychophysical measures of unconscious visual perception and using fMRI to study the neural correlates of visual consciousness.

Zachary Cohen

Dr. Cohen is a post-doctoral fellow whose work focuses on precision and personalized approaches to mental health treatment. The goal of his research is to better understand how and for whom specific treatments (or treatment elements) will work, and to use that information to optimize response. Zach has spent the past three years working with Dr. Craske and an incredibly talented and passionate team to develop a digital therapy ecosystem designed specifically to build and evaluate personalization algorithms. While in graduate school at the University of Pennsylvania, he developed the Personalized Advantage Index (PAI) approach with his mentor Dr. Robert DeRubeis, and founded a biannual international conference called the Treatment Selection Idea Lab (
