I am an assistant professor in the Theoretical Computer Science group (TCS) at Aalto University. I create and analyse algorithms that deal with geometric content, such as points, curves, or shapes, as well as porblems involving spatial networks. My field, computational geometry, is the theoretical basis for several areas, including computer graphics and vision, robot motion planning, computer aided design and manufacturing. I aim to discover many ways of using geometric structure to our advantage when designing algorithms.
