For over 25 years I have been interested in the psychological adjustment of children and adults undergoing treatment for cancer. I particularly studied the impact of bone marrow transplantation on pediatric and adult patients and their families. Increasing survival of cancer patients has led to my strong interest in survivorship, resilience, and quality of life. More recently, my work has taken on the added focus of exploring the psychological impact of advances in cancer genetics. I have studied the psychosocial outcomes of women and men undergoing cancer genetic testing for p53 and BRCA1/2 and the experience of women undergoing prophylactic mastectomy for increased hereditary cancer risk.
