About Me

Hello! I'm Minbok Wi.

I am currently a Staff Engineer at the AP Architecture Group (MX), Samsung Electronics.

I earned my Ph.D. from Seoul National University, where I was advised by Prof. Jung Ho Ahn. I also spent time as a Visiting Scholar at UT Austin, working with Prof. Mattan Erez.

My doctoral research focused on the security and reliability of memory systems within computer architecture.
