My name is Nicholas Baltzer, I’m a PhD student in bioinformatics at Uppsala university. I have a BSc in Computer Science and an MSc in bioinformatics. I particularly like working with heuristics, programming, and non-trivial computations. I’m from Sweden. The goal of my project is to develop and eventually apply a predictive machine-learning algorithm to the Swedish screening programme. The idea is to use predictions to stratify women into risk groups and adjust the intensity of the screening programme accordingly for each woman. I work at the department of cell- and molecular biology, Uppsala University, under Jan Komorowski, my supervisor, and I do this in collaboration with the department of Medicine, Epidemiology, and Biostatistics at Karolinska institutet, where Karin Sundström is my supervisor.
