I’m a DPhil student in Computer Science at the University of Oxford, supervised by Edith Elkind and supported by an EPSRC scholarship. My research interests include computational social choice, algorithmic game theory, and mechanism design. I enjoy working on problems motivated by real-world applications as well as on foundational theoretical questions.
Currently, I am a Research Scientist Intern in the AI & Society group at Meta FAIR. In January 2027 I will be starting as a Assistant Research Professor at the Center for Data Science for Enterprise & Society at Cornell University.
Previously in 2025/2026, I worked part-time on a project on aggregating safety preferences within ARIA’s Safeguarded AI program, and part-time for Meta FAIR under Max Nickel on pluralistic alignment. In summer 2025 I participated in the PIBBSS research fellowship. I had the pleasure to visit Vince Conitzer and his gorup FOCAL at CMU in spring 25' and also shorter research visits with Piotr Skowron at the University of Warsaw and Piotr Faliszewski at the AGH Krakow.
Pior to my PhD, I completed an MSc in Mathematics and Foundations of Computer Science (MFoCS) at the University of Oxford, and a BSc (Hons) in Computing Science and Mathematics at the University of Glasgow.
