Dr Sebastian Nijman develops new approaches to study signalling networks in cancer cells and uncover specific weaknesses, particularly in breast and lung cancer. This can be used to develop more effective drugs and to better guide treatment decisions. In the context of cancer, genetic diversity means that we respond differently to various treatments. Pharmacogenomics sits at the intersection between genetics and drugs. Better understanding of the genetic landscape of cancer and the recent increase of targeted drugs allow us to better match patients with the best treatments, improving care.
