I am a postdoc at the Royal Institute of Technology (KTH), where I also earned my PhD under Maurice Duits in 2020. In between I was a postdoc at the University of Michigan and most recently at MIT. At KTH I am part of the Random Matrix Theory and Random Geometry (RMRG) research group. Here is my most recent CV .

My research focuses on asymptotic properties of probabilistic models in mathematical statistical mechanics, with the main focus on dimer models. I employ integrable tools such as orthogonal polynomials, Riemann-Hilbert problems, and Wiener-Hopf factorizations, alongside methods from algebraic geometry and, most recently, from tropical geometry.

Publications and preprints


Random samples of the Aztec diamond dimer model with doubly periodic edge weights. Examples with finite temperature as well as examples with zero temperature.

3x3-periodic Aztec diamond 2x3-periodic Aztec diamond with arctic curve 2x1-periodic Aztec diamond with arctic curve 2x2-periodic Aztec diamond with arctic curve
3x3-periodic Aztec diamond zero-tempreature 2x2-periodic Aztec diamond zero-temperature 2x2-periodic Aztec diamond zero-temperature with arctic curve 4x4-periodic Aztec diamond with parameterization zero-temperature
The tiling pictures are generated using a program that was kindly provided by Sunil Chhita. For 3D pictures of the height function of the Aztec diamond see the following webpage by Alexei Borodin and Matvey Borodin.
