I am a fifth 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. From October 2026, I will be a postdoc in the Combinatorics group at the University of Barcelona under the supervision of Vincent Pilaud and Arnau Padrol (followed by a four-year postdoctoral scholarship by the Wallenberg foundation shared betweewn MPI CBG and a swedish university).

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.
