Research Areas

My general research interests are in the areas of (selection)

• Information-theoretic Privacy and Security

• Coding Theory 

(e.g., Reliable/Robust/Secure/Stealth/Covert/Resilient Communications and Data Storage)

• Secure Integrated Sensing and Communications (ISAC)

• Physical Layer Security (PLS)

• Neural Error-correcting Code (ECC) Design for Communications

• Energy and Hardware Efficient AIoT & Edge AI Algorithms for Edge Learning

• Doubly-exponential Identification via Channels (from Ahlswede&Dueck) 

     (e.g., sensor/watermark identification in Post-Shannon Communications)

• Federated Learning (FL) with Information-theoretic and Differential Privacy Guarantees

• Biometric Secrecy Systems and Physical Unclonable Functions (PUFs)

• Differential Privacy (DP) for Correlated Data 

     (e.g., Eye-tracking for Immersive XR Experiences in Metaverse)

• Over-the-Air (OtA) Coordination and Cooperation

• Distributed Secure and Private (Multi-Party) Multi-Function Computations

• Information Bottleneck Method

• Statistical Signal Processing for Secret Key Agreement

• Post-quantum Cryptography (PQC) 

• Secure Multiple-input Multiple-output (MIMO) Wireless sub-Terahertz (sub-THz) Communications

• Algorithm Design for Quantum Key Distribution (QKD) (from Maurer) 

• (Conditional) Mutual Information Estimation via Neural Networks.
