Research Interests

Computer architecture, focusing on productive hardware design flows (LiveHD and ESESC), out-of-order cores, and RISC-V verification. Past projects with Thread Level Speculation, infrared thermal measurements and power modeling, and design effort metrics/models.

Looking for good MS/PhD students. We have many projects to help, contact me if you are looking for a MS/PhD thesis.

Funding MS/PhD Students

I have funding opportunities for UCSC PhD and MS students working on more productive hardware design flows. Check the current list of projects available for MS students at projects.md. Contact me if you are interested.
Besides hardware productivity, I am also looking for motivated PhD in other areas in computer architecture.

The MASC group is part of UC Santa Cruz Hardware Systems Collective. The collective is a group of researchers at the Computer Science Department investigating how to design/build/architect/secure/optimize/integrate/program the next generation of hardware.
