Current Research

My current research is focused on improving and evaluating training in psychotherapy. I am especially interested in evaluating training focused on process-sensitivity including acuity and responsivity to resistance and ambivalence markers. The development of therapist skill using deliberate practice methods is also of interest. In addition, my research is focused on the application of Motivational Interviewing (MI) to anxiety disorders and the integration of MI with Cognitive Behavioral Therapy (CBT) for anxiety. My collaborators and I have conducted several clinical trials to examine the efficacy of MI-CBT. My research is focused on understanding resistance in psychotherapy, especially disharmony in the therapeutic relationship, lack of collaboration, and disengagement.
