Dr. Carlsson, MD, PhD, MPH is an epidemiologist and cancer researcher at Memorial Sloan Kettering Cancer Center in New York, USA, with 15 years of prostate cancer research experience and over 100 scientific publications. She is an investigator in the world’s largest randomized study of screening for prostate cancer, the European Randomized Study of Screening for Prostate Cancer. Her work on prostate-specific antigen (PSA) screening has helped inform national screening guidelines around the world. Dr. Carlsson’s current research aims at finding a better balance between the harms and benefits of PSA screening, using multiplex testing and risk-stratified strategies that incorporate clinical information, biomarkers and magnetic resonance imaging. Dr. Carlsson is funded by a career development award from the US National Institutes of Health/National Cancer Institute to study the psychology of decision making to better understand patients’ information needs, which will facilitate the development of better decision aids for cancer screening and lead to improved shared decision-making.
