MeiLu and Adam visited Lund University in Sweden for the 2022 ELLIIT Focus Period on Data-driven modelling and learning for cancer immunotherapy. The goals were to ”unite young international scholars, ELLIIT researchers and other top international academics active in domains such as systems biology, cancer treatment, machine learning and dynamical systems,” and indeed the participants were diverse! From clinicians to a Fields medalist. Yet we managed to find common ground across these broad domains.
