Dr. Sarina Schwarz

My research mainly focusses on the early detection and prevention of cancer. I conducted my PhD in the fields of colorectal cancer screening and I continue to give my attention to this topic. This includes studies on the effectiveness, utilization and quality of colonoscopies. I am also involved in other projects within the field of cancer epidemiology (e.g., HPV vaccination for cervical cancer prevention) and pharmacoepidemiology.
