My research lies in the ICT field with primary focuses on sinal design, error-correcting codes, cryptography, and security (short introductory videos for , , and ). More specifically, my research interests include

• signal design: signals/waveforms with desirable correlation, peak-to-average power ratio (PAPR), ambiguity for reliable and efficient wireless communications 
• coding theory: error-correction codes in Hamming metric and rank metric, and their applications for reliable data communication and storage
• cryptography: symmetric cryptographic primitives, homomorphic encryptions, searchable encryptions, code-based cryptography
• security: intrusion detection and secure authentication
• blockchain: design and applications of blockchain
• discrete mathematics: permutations polynomials, sequences, cryptographically strong functions and interplay among them
