Bio & CV(English, Hungarian)

I am a Marie Curie fellow at the Rényi Institute. My main research topic is quantum algorithms and complexity, with a recent focus on stochastic quantum processes related to Glauber and Metropolis dynamics, and more generally quantum walks and quantum linear algebra methods (quantum singular value transformation and the block-encoding framework) with application in optimization and related fields. I received my PhD in 2019 from the University of Amsterdam, where I was supervised by Ronald de Wolf and co-supervised by Harry Buhrman at CWI/QuSoft. Between 2019 and 2021 I was an IQIM postdoctoral fellow at Caltech, meanwhile I received the ERCIM Cor Baayen Young Researcher Award in 2019 and was a Google Research Fellow at the Simons Institute for the Theory of Computing in Berkeley during the "The Quantum Wave in Computing" program in the spring of 2020.
