About me

Welcome! I am a second year PhD Student at the Weierstraß Institute (WIAS) in the research group Probabilistic Methods for Dynamic Communication Networks under the supervision of Benedikt Jahnel and a Phase II Student at the Berlin Mathematical School.

Since May 2024, I am a co-organiser of the Postgraduate Online Probability Seminar (POPS), a monthly online seminar which provides a platform for doctoral students and post-docs from all over the world to present and promote their research in areas related to probability and its applications. If you are interested in presenting your work or want to suggest a speaker, feel free to reach out by email!

I am co-founder of BLISS, a student-run club connecting interested students with AI/ML researchers and practicioners through weekly reading groups, invited talks, and coding challenges. If you want to know more about it or join one of our weekly meetings, write me an email!

Research interests

My current research is mainly focused on the long-time behaviour of large-scale systems of interacting particles with some underlying spatial structure. A large part of this study is devoted to identifying invariant measures and their domains of attraction. In principle, however, it is possible for an interacting particle system not to converge to an invariant measure at all. One way in which this can happen is through periodic behavior. There are several known examples of interacting particle systems that in the mean-field limit exhibit periodic behavior, but much less is known about spatially extended systems. At the moment I am investigating whether it is possible for non-degenerate interacting particle systems to exhibit periodic behaviour in two spatial dimensions and whether time-periodic behaviour can also happen in IPS that admit a reversible measure.
