Michał Osadnk

Ph.D. Researcher

I am a Ph.D. researcher at Aalto University under a joint supervision of Russell W. F. Lai and Parinya Chalermsook.


My research interests include lattice-based cryptography, abstract algebra, succinct argument systems, time-based primitives, and fully homomorphic encryption. I enjoy programming and the practical aspects of cryptosystems. I am very open to new collaborations and exploring new areas of cryptography.


Before starting my Ph.D. studies in 2023, I worked as a research assistant at Parinya Chalermsook's research group at Aalto (2021-2023), where I also finished my M.Sc. in 2023. I worked as a full-time employee or long-term consultant in the following companies: Para (form. Capsule; 2022-2023), Rainbow (2020-2022), FlipFit (2020), Software Mansion (2017-2020), Printbox (2016). I was interning in Meta (2019) and Palantir (2021). Throughout all of those involvements, I mainly focused on mobile engineering, web development, blockchain integrations, and animations. My most significant open-source projects are available on my GitHub.
