Stanislaw Radziszowski

Stanislaw Radziszowski is a Professor in the Department of Computer Science at Rochester Institute of Technology's Golisano College of Computing and Information Sciences. He has been at RIT since 1984, after working at the National Autonomous University of Mexico from 1980-1984. His academic career includes multiple visiting positions at the Australian National University in the 1990s and ongoing collaborations with institutions in Poland.

Radziszowski earned his Ph.D. in Mathematics and Computer Science from the University of Warsaw in 1980, advised by Antoni Kreczmar and Andrzej Salwicki. His educational background includes BS and MS degrees from the same institution.

Dr. Radziszowski's primary research focuses on combinatorial computing, with special emphasis on Ramsey theory and computational design theory. His "Small Ramsey Numbers" survey has become a standard reference in the field. More recently, he has expanded into applied cryptography, particularly post-quantum cryptography, leading to collaborations with the Computer Engineering Department. His work often combines theoretical insights with practical computational approaches to solve classical problems in combinatorics and graph theory.

His recent publications demonstrate a growing focus on cryptographic applications, including post-quantum cryptography education, analysis of the MK-3 Authenticated Encryption Algorithm, and homomorphic encryption implementations. These works reflect his ability to bridge theoretical mathematics with practical security applications, particularly in hardware implementations and side-channel resistance.

Dr. Radziszowski has made significant contributions to Ramsey theory, most notably computing R(4,5)=25 with Brendan McKay and improving bounds for R(5,5) and R(4,6). His survey "Small Ramsey Numbers" is a regularly updated reference in the field. He has also contributed to computational design theory, proving nonexistence of certain block designs.

As an educator, Radziszowski teaches theory-oriented courses including Introduction to Cryptography, Foundations of Cryptography, and Quantum-Resistant Cryptography. He has developed specialized courses on combinatorial computing and has supervised numerous MS theses and projects. His recent work on post-quantum cryptography has led to educational initiatives in this emerging field.

Dr. Radziszowski maintains active research collaborations, particularly with Xiaodong Xu on Ramsey and Folkman problems, and with Marcin Lukowiak on cryptographic implementations. His work often bridges the gap between theoretical mathematics and practical computing applications.
