Johan Karlsson is a Professor in the Department of Mathematics at KTH Royal Institute of Technology, Sweden. He serves as Associate Director Executive Research at Digital Futures, a cross-disciplinary research center focusing on digital technologies for societal challenges. He holds a PhD in Optimization and Systems Theory from KTH (2008) and an MSc in Engineering Physics (2003). His research focuses on inverse problems, optimization, model reduction, and their applications in remote sensing, signal processing, and control theory. He leads the Decision-making in Critical Societal Infrastructures (DEMOCRITUS) project and collaborates on initiatives like the Lindquist Symposium in Systems Theory. Teaching includes advanced courses such as Optimal Control and Convexity and Optimization in Linear Spaces . He supervises PhD students and has authored/co-authored numerous papers in journals like SIAM Journal on Control and Optimization and IEEE Transactions on Automatic Control . His work integrates optimal transport theory, control systems, and computational methods to address complex engineering and environmental challenges. Key affiliations include KTH’s Department of Mathematics and Digital Futures, with collaborations across academia and industry. His research group actively engages in workshops, conferences, and interdisciplinary projects to advance theoretical and applied aspects of optimization and systems theory.
