Nena Bollen holds a master’s degree in bio-statistics from the KULeuven. Her interest in public health was sparked (a bit unconventionally) during her bachelor’s degree in sociology, where she became fascinated by how social factors can influence health on a population level. This interest has grown from social epidemiology to epidemiology in general, finding a niche in the study of infectious diseases. Her field of study lies in estimating viral spread using phylogeographic models. She also has a fondness for data visualisation projects.
