Dr. Kazantzis is internationally renowned for his contributions to the field of Cognitive Behavior Therapy (CBT). His current research focus is on quantifying and enhancing high-quality CBT practice in clinical trial, university clinic, and community-based settings by collaborating with psychologists in order to (a) identify conditions that enhance engagement and outcomes; (b) discover key processes of effective cognitive behaviour therapies; (c) develop and test research-supported enhancements to increase the practical usefulness of cognitive behaviour therapies; and (d) understand and improve psychologists training and adoption of research-supported therapy practices. Before joining the academic staff at Monash University, he worked as a Honorary and contract clinical psychologist across a range of inpatient and community public health settings, and ran a successful independent private practice alongside his previous academic appointments at Massey University and La Trobe University. He also completed 12 months of postdoctoral training in CBT at the Beck Institute for Cognitive Behavior Therapy. He continues to provide clinical training and supervision to provisionally registered psychologists within Monash University's Psychology Clinic. 

Dr. Kazantzis' research has resulted in over 140 scholarly publications, as well as books that disseminate the results of his research for the practising clinician.

He is immediate past Editor-in-Chief for Australian Psychologist, is presently Associate Editor for Cognitive Therapy and Research and International Journal of Cognitive Therapy, and is Editor-elect for Cognitive and Behavioral Practice. He served as Deputy Chair of the Scientific Comittee for the 8th World Congress of Behavior and Cognitive Therapies.
