About me
About me
I am currently an EPSRC Postdoctoral Research Fellow at the London School of Economics. My project is called "Substructures in large graphs and hypergraphs".
Previously, I was a researcher at SW7 Group in London, working on problems from machine learning, statistics, and optimisation applied to tech and finance.
Before that, I obtained my PhD from the University of Warwick under the supervision of Prof Daniel Král'.
Before that, I did Parts I-III of the Mathematical Tripos at Murray Edwards College, University of Cambridge.

Research
My interests lie mainly in the area of extremal combinatorics. In the past I have looked at ways to decompose the edge set of a given graph into small or sparse subgraphs, limits of combinatorial objects and their applications to extremal problems, and graph tilings in various settings.

I am co-organising the London Colloquia in Combinatorics, which will take place on 8 May 2024 at UCL and 9 May 2023 at LSE. I was involved in organising the previous edition as well.
I co-organised the LSE Workshop in Extremal and Probabilistic Combinatorics, which took place 12-16 Dec 2022 at LSE.
I co-organised Young Researchers in Combinatorics which took place in July 2022 at ICMS, University of Edinburgh.
