Markus Wagner from Monash University works on topics that range from mathematical runtime analysis of heuristic optimisation algorithms and theory-guided algorithm design to applications of heuristic methods to software engineering and renewable energy production. While his research is fundamental at times, he is no stranger to industry-funded research; some of his translational projects are funded by Google, Facebook, and by several companies in defence and mining. Markus has been deeply passionate about sustainability since his high-school days… and still is. He serves as the first ever Sustainability Officer (since 2019) at the ACM Special Interest Group on Genetic and Evolutionary Computation, he founded the IEEE CIS Task Force on Computational Intelligence in the Energy Domain, and he is Associate Director for Smart Energy Systems at the Monash Energy Institute.
