Ass.Prof. PhD

Secure Systems, Assistant Professor

Sujoy Sinha Roy is an assistant professor at IAIK,  the Graz University of Technology. He works on secure and efficient implementation of cryptographic algorithms on hardware and software platforms. He received the PhD degree in 2017 with 'Summa cum laude with congratulations from the examination committee' from COSIC, KU Leuven, Belgium. His doctoral thesis was awarded the 'IBM Innovation Award 2018' that recognizes an outstanding doctoral thesis in informatics. He is a co-designer of ‘Saber’ which is a finalist in NIST’s Post-Quantum Cryptography Standardization Project. Before joining TU Graz, he worked as an assistant professor at the University of Birmingham's Security and Privacy group, from Sep 2018 to Nov 2020.
