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. As part of York’s outstanding psychotherapy process research faculty, my current research is focused on understanding resistance in psychotherapy, especially disharmony in the therapeutic relationship, lack of collaboration, and disengagement. I am also interested in client ambivalence about change, as well as outcome expectations, and how these impact the unfolding process in therapy. In general, I am particularly interested in studying and training in core facilitative relationship skills such as empathy, alliance- building, and client-centered therapist attitudes. Relatedly, I have developed a strong interest in training therapists in process-sensitivity, including process observational skills and responsivity to moment-to-moment key contextual markers in the therapy process.
