Feea Leifker

Feea Leifker is a licensed clinical psychologist and Director of the EOS Foundation Behavioral Health Clinic. Her research has focused on the bidirectional association between intimate relationship functioning and psychopathology, particularly posttraumatic stress disorder (PTSD), anxiety disorders, and suicide. She is particularly interested in the function of social support, intimacy, and aggression within the couple context and how these processes function when one or both partners have some form of psychopathology. She hopes that such research can inform intervention adaptation or development to simultaneously improve relationship functioning and mental health.
