BIOGRAPHY
Shahram Jahani is a lecturer at the UCF Department of Computer Science with a research background in high-performance computing, cryptography and number theory-based public-key systems. His work focuses on the design and optimization of mathematical frameworks to enhance the efficiency and security of cryptographic algorithms. He is also the originator of the ZOT-Binary and ZOT-MK number systems, developed to improve big-integer multiplication and cryptographic operations.
He earned his doctoral and master’s degrees and in computer science from Universiti Sains Malaysia, with research centered on computational mathematics and security. He also holds a bachelor’s degree in electrical engineering. Prior to and alongside his academic work, Jahani spent over a decade in the industrial sector, where he led engineering teams and applied systems such as total productive maintenance, management information systems and overall equipment efficiency across large-scale manufacturing operations. He also specialized in industrial automation, including the upgrade and integration of PLC systems, industrial networking, and real-time control technologies to improve productivity and reliability in automated environments.
