About

I am a mathematics student at Aalto University, Finland, having received my master's degree in May 2022. I started my doctoral studies at Aalto University in August 2022 under the supervision of Professor Camilla Hollanti in the ANTA group. For 2023—2025 I am supported by the Vilho, Yrjö and Kalle Väisälä Foundation of the Finnish Academy of Science and Letters.

My research interests include applications of coding theory in information-theoretically secure distributed computing. For my master's thesis I worked on secure distributed matrix multiplication and was awarded the 2023 Ernst Lindelöf prize for the best master's thesis in mathematics by the Finnish Mathematical Society. Currently I am working on the mathematical foundations of secure distributed computation by studying methods from algebraic coding theory and information theory. I have an Erdős number of 4.
