Welcome to Intelligent Storage System Laboratory!

Student Recruiting

1. There are TAs and RAs openings for Ph.D. students in Dr. Zhang’s group. Interested students shall contact him by emailing their CVs and Tofel/GRE scores.

2. Summer internship at the Berkeley Lab: multiple positions are available for undergraduate and graduate students. These projects require C/C++ and are related to high-performance computing, OS, and system programming. If selected, the lab will pay $600/week for 9 weeks for undergraduate students plus a housing supplement of $3000. (The minimum GPA requirement is 3.0/4 and students must be US citizens or permanent residents at the time of applying.)

3. NSF REU site for Advancing Data-Driven Computational Simulations and Experiments: more information can be found here (https://reu.encs.vancouver.wsu.edu/).
