معرفی
Ragnar Freij-Hollanti is a Senior University Lecturer at the Department of Mathematics and Systems Analysis, Aalto University, Finland. He holds a PhD from Chalmers University of Technology, supervised by Professors Jeff Steif and Johan Wästlund. His research focuses on combinatorial and algebraic methods in coding theory, with applications to privacy and security in distributed systems. He also explores polytope and matroid theory, often linking abstract mathematics to practical problems in storage and computation.
Education: PhD in Mathematics (Chalmers University of Technology), MSc in Mathematics (not explicitly stated but implied by career progression).
Research Interests:
- Coding Theory and Cryptography
- Privacy-Preserving Distributed Systems
- Combinatorial Optimization and Matroid Theory
- Algebraic Geometry Applications
- Lattice-Based Cryptography
Publications: Over 30 peer-reviewed articles, including recent work on secure distributed matrix multiplication, quantum PIR, and lattice coding. His research often bridges theory and practice, addressing challenges in distributed storage and computation security.
Advising: Supervises BSc, MSc, and PhD theses in combinatorics and coding theory. Active in organizing seminars like the Algebra and Discrete Math seminar.
Labs/Teams: Member of the Algebra, Number Theory, and Applications (ANTA) research group at Aalto University, focusing on applied algebra and cryptography.
