Hi! This is my area of interest and I applied everywhere that had a remotely related program. Granted, specifically I was looking at psych epi.
Emory has a mental health certificate. No matter what your concentration is, you can add on this certificate.
Washington University doesn't have a "concentration," but they have several people researching in this area and fellowship opportunities.
VCU has a cluster of research going on in this area.
U of Florida has a psych epi program for medical professionals and therefore several related courses you can take, as well as multiple faculty members doing related research.
Harvard has a neuropsychiatric epi concentration.
Columbia has several courses you can take in this area as well as a global mental health program and other related initiatives.
U of Pittsburgh has a psych epi concentration and partnerships with Western Psychiatric.
I have more info on all of these if you have questions.
