I'm really interested in solving real-world security and privacy problems through mathematical and cryptographic tools. The following topics are my current interests.

Cryptography

• • Privacy Enhancing Technologies (in a cryptographic approach)

  • Devising Cryptographic Tools for Real-valued Fuzzy Data

Secure AI & Biometrics

• • Security Analysis on Deep Learning-based Face Recognition Systems

  • Biometric Template Protection (in a cryptographic approach)

  • Adversarial Machine Learning (in theoretical perspective)

Miscellaneous

• • Computational Number Theory & Algorithms

  • Complexity Theory
