Søren M. Bentzen, MSc, PhD, DMSc, Professor, Director of the Biostatistics Shared Service, University of Maryland Greenebaum Cancer Center, and Director of the Division of Biostatistics and Bioinformatics, Department of Epidemiology and Public Health, University of Maryland School of Medicine since 2013. Dr. Bentzen is also an Adjunct Professor of Radiobiology and Medical Physics, University of Copenhagen, Denmark. His previous appointments include MD Anderson Cancer Center (1987-1988), Danish Cancer Society/Aarhus University (1988-1997), Gray Laboratory/Mount Vernon Hospital, London (1998-2004), and University of Wisconsin School of Medicine and Public Health (2005-2013) where he was a professor of Human Oncology and held affiliate faculty positions in the departments of Biostatistics & Medical Informatics and in Medical Physics.
Dr. Bentzen received a MSc in physics and mathematics (1981), a PhD in medical image analysis (1986), and a DMSc (doctor of medical science) in quantitative clinical radiobiology (1994), all from Aarhus University, Denmark. He has published >370 original papers and book chapters, and has presented >300 invited lectures. He currently serves on 10 international cancer journal editorial boards. His research has been recognized by 24 awards and honors, including the ESTRO Breuer Gold Medal (2003), the MD Anderson Distinguished Alumnus Award (2008), and Honorary Life Memberships of the Association of Radiation Oncologists of India (2008) and the Belgian Society for Therapeutic Radiology and Oncology (2009). He held an Honorary Professorship at University College London (2000-2005) and was a Visiting Statistician to the Medical Research Council Clinical Trials Office, London, UK (1998-2004).
Dr. Bentzen is currently the principal investigator of a randomized controlled phase III trial of resource sparing radiation therapy for locally-advanced squamous cell carcinoma of the head and neck, sponsored by the International Atomic Energy Agency; member of the Previously-untreated Locally Advanced Disease Task Force of the Head and Neck Cancer Steering Committee of the National Cancer Institute (NCI); founding member of the Steering Committee of the International Radiogenomics Consortium; member of the UICC Global Task Force on Radiotherapy for Cancer Control; member of the Board of Directors of the International Commission on Radiation Units; member of the Steering Committee of PENTEC (PEdiatric Normal Tissue Effects in the Clinic) group. He was one of the leaders of the QUANTEC (Quantitative Analyses of Normal Tissue Effects in the Clinic) initiative (2007-2010) and member of the ASTRO Task Force to develop an evidence-based guideline on the appropriate fractionation for whole breast irradiation (2009-2010). He has served as chair or member of 17 (seven currently active) Independent Data and Safety Monitoring Committees or Trial Steering Committees. He is co-chair for Translational Research for two open RTOG phase III trials.
His main research interests include bioeffect modeling; biomathematics; applied biostatistics; clinical trial design; evidence-based medicine; late effects of radiotherapy; clinical radiobiology; integration of data from genomics, proteomics, and molecular imaging into novel therapeutic strategies.
In addition to his role as Director of the Biostatistics Shared Service, Dr. Bentzen is a member of the Experimental Therapeutics Program within the University of Maryland Marlene and Stewart Greenebaum Cancer Center Program in Oncology. He collaborates with both basic and clinical researchers, aiming for the rapid translation of discoveries from the laboratory to the clinic. Dr. Bentzen’s research focuses on three broad fields: normal-tissue radiation biology; biomarkers, including genomic and imaging biomarkers, in predictive oncology; and the pre-clinical and clinical development of drug-radiation combinations.
