He is a past president of the American Psychological Association’s Society for Psychological Hypnosis (Division 30), and a Fellow of the American Psychological Association. He received his Ph.D. in clinical psychology from the University of Connecticut in 1995, completed a fellowship Psycho-oncology at Memorial Sloan-Kettering Cancer Center in 1997, and received post-doctoral training in health economics at Columbia University. He has published more than 90 peer-reviewed empirical articles, and has received funding from the National Cancer Institute and the American Cancer Society. Dr. Montgomery has extensive experience in studying breast cancer patients’ experiences of cancer and its treatment, and using his discoveries to develop psychosocial interventions to improve patients’ quality of life. Dr. Montgomery’s work has been recognized not only in scholarly contexts (e.g., conferences, journals), but also in the national and international media. His work has been discussed in multiple media outlets, including: New York Times, Wall Street Journal, Good Morning America, ABC News, CBS News, and NPR. Dr. Montgomery is also committed to mentoring and cancer education, through his stewardship of NIH R25E and R25T awards, through his service to NCI Review committees, and through his direct mentoring of pre- and post-doctoral fellows in cancer prevention and control.

Dr. Montgomery’s research focuses on developing, testing and disseminating psychological and integrative interventions to reduce suffering related to cancer and its treatment. Critical findings are: 1) Through an RCT of breast conserving surgery patients, he and his group found that patients who received a brief presurgery hypnosis intervention needed less propofol and lidocaine; reported less pain intensity, pain unpleasantness, nausea, fatigue, discomfort, and emotional upset; and, cost the institution $772.71 less per patient than patients in an attention control group. 2) In an RCT of breast cancer radiotherapy patients, he found that that a brief intervention including cognitive-behavioral therapy plus hypnosis (CBTH) reduced fatigue in patients during radiotherapy, and for up to six months following radiotherapy. Results support CBTH as a highly effective means for controlling and potentially preventing fatigue in breast cancer radiotherapy patients. 3) Throughout his program of research, Dr. Montgomery has demonstrated that response expectancies and emotional distress play important roles in the development of cancer patients’ treatment-related side effects (e.g., chemotherapy-related nausea, postsurgical quality of life). 4) Dr. Montgomery is presently working on developing and testing E-Learning training programs to teach psychosocial cancer care providers in the use of E-Counseling with cancer patients and survivors. 5) Dr. Montgomery was recently funded to study the role of hypnosis in reducing musculoskeletal pain and improving medication adherence in breast cancer survivors prescribed aromatase inhibitors. Overall, Dr. Montgomery’s program of research focuses on examining, with scientific rigor, the effects of behavioral medicine and integrative interventions on the lives of cancer patients. Scientific inquiry will permit a culling out of efficacious applications. Perhaps most importantly however, the research findings ensuing from this program (and dissemination of the approaches discovered therein) may lead to sweeping changes in the treatment and care of cancer patients, and as a consequence, to major improvements in their quality of life.
