Universitas Indonesia

As a lecturer at the University of Indonesia, I teach several undergraduate courses each semester, primarily in Algebra and Cryptography. In addition to teaching, I actively seek to supervise students’ research projects in mathematical cryptography and computational algebra.

Students’ research projects:

• Brayen Damara: The Shifted Discrete Logarithm Problem on Finite Semigroups as a Basis for Post-Quantum Cryptography Protocols
• Muhammad Ferry Husnil: On the Classical Hardness of the Semidirect Discrete Logarithm Problem in Finite Groups
• Fritz Adelbertus Sitindaon: Hawk Signature Protocol
• Nurshafa Aliya: Tropical Cryptography

Budapest University of Technology and Economics

During my PhD, I taught some algebra and computer science courses.

• Introduction to Algebra 2 (Spring 2022)
• Introduction to Algebra 1 (Fall 2021)
• Informatics 2 (Spring 2021)
