Research

My recent research centers on hardware security (roots of trust based on physical unclonable functions, side-channel attacks and countermeasures, realizations of post-quantum cryptography), ML algorithm and hardware codesign, and approximate computing.

Teaching

• Fall 2024: EE 382V: ML Hardware-Algorithm Codesign
• Fall 2024: EE382M: Design for Low Power and Robustness
• Spring 2025: EE316: Digital Logic Design

Advising

• Policies related to M.S. degrees in ICS can be found in the ICS Graduate Advising Notes

News

• A post-doctoral position starting in Fall 2024 is available for a project involving applied ML, modeling, and optimization. Please contact me if interested.
