Melina Arnold

Melina Arnold is a cancer epidemiologist at the German Cancer Research Center (DKFZ) specializing in the relationship between obesity, body composition, and cancer risk. Her research employs advanced epidemiological methods including Mendelian randomization and longitudinal cohort analysis across multiple international studies.

Her research focuses on how duration of overweight status affects cancer development, with particular emphasis on obesity-related cancers including breast and colorectal cancer. She has conducted extensive work with European cohort studies including the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

Arnold's publications demonstrate significant contributions to understanding how cumulative exposure to excess body weight influences cancer risk and survival outcomes. Her work has been published in high-impact journals including Circulation and the European Journal of Epidemiology.

Her methodological expertise includes analyzing longitudinal BMI trajectories, assessing cumulative measures of excess weight, and conducting Mendelian randomization analyses to establish causal relationships between risk factors and disease outcomes.
