Dr. Ogrodniczuk is an Associate Professor in the Department of Psychiatry at the University of British Columbia. His research program examines relationships among pre-therapy characteristics of patients, process patterns believed to mediate change, and multivariate outcomes. These relationships are explored in different types of psychotherapy for different types of patient problems. He is particularly interested in group psychotherapy, psychotherapy for the medically ill, and personality disorder.
