I successfully defended my Ph.D. Thesis in December 2024 with title Complexity in Decision-making with Applications to Large-scale and Human-in-the-loop Systems, supervised by Prof. Karl H. Johansson and co-supervised by Prof. Henrik Sandberg at the Division of Decision and Control Systems, KTH Royal Institute of Technology.

My research interests are in the intersection of control and complexity, proposing low-complexity control algorithms and computationally efficient design methods, and interactive controllers for human-in-the-loop systems. I also have a broad interest in applied mathematics in general, such as graph theory, machine learning and game theory. I received an Outstanding Paper Prize at CDC 2021 and was one of the Best Student Paper Finalists at ECC 2019.

Background: Before starting my Ph.D., I received a B.Sc. degree in Engineering Physics from KTH Royal Institute of Technology and a M.Sc. degree in Mathematics jointly from KTH Royal Institute of Technology and Stockholm University, Sweden. During my studies, I was also a research visitor at Caltech and UC Berkeley, US.
