I co-developed and taught T4CS(Terminals for Computer Scientists) at UCSD as CSE80.


My research interests span software security, systems, and hardware architecture.
I put special focus on the impact of hardware design on high-level software security.

My current projects are:
The Keystone TEE framework for RISC-V.
FPGA analog side-channels.
