Dr. James Trauer's team at Monash University uses Buildkite, EC2, and S3 to inform COVID-19 government policy decisions through cutting-edge modelling techniques. Their open source projects, Summer and AuTuMN, help generate COVID-19 modelling results using data such as case numbers, population density, hospitalizations, ICU admissions, and vaccination rates. The team's approach to scientific modelling is unique in its use of a modern tech stack and software engineering practices, including automated testing and modular code base. They believe that the convergence of scientific modelling and software engineering will become more widespread in the future.
