Description of Research Expertise

Research related to pain including the use of new pain medications, brain function in people with pain, complementary and alternative therapies, and new methodologies for understanding how patients report their pain in clinical trials. Current research includes ongoing studies of acupuncture for the treatment of pain in osteo-arthritis patients and chronic fatigue in cancer patients, brain imaging of patients with pain, and studies of cancer treatment related pain.

Description of Clinical Expertise

Focuses on all aspects of pain and symptom therapy in cancer patients as a member of the Symptom and Palliative Care Team and as a collaborator in the development of a multi-disciplinary program for the evaluation and treatment of patients with pain.
