I am a last-year PhD student in the "Algebraic, Combinatorics, Geometry, Topology (ACGT)" division at KTH, and a member of the combinatorics group. I have been working in problems relating to discrete geometry, combinatorics and algebraic statistics. My supervisors are Liam Solus (main), Katharina Jochemko and Johan Håstad.

My PhD is funded through the Wallenberg AI, Autonomous Systems, and Software Program (WASP). I am also a member of the WASP graduate program. The graduate school within WASP is dedicated to providing the skills needed to analyze, develop, and contribute to the interdisciplinary area of ​​artificial intelligence, autonomous systems and software. The graduate school actively supports forming a strong multi-disciplinary and international professional network between PhD students, researchers and industry collaborators.
