I'm a graduate student in Computer Science at University of California, Berkeley (UC Berkeley). I'm working at RISELab (Real-time Intelligent Secure Explainable systems Lab), the successor of AMPLab (Algorithms, Machines, and People Lab) where Apache Spark was born. In the RISELab, I research computer systems and programming language techniques to strengthen the security of data processing. I am advised by Raluca Ada Popa and collaborating with other faculty and students in the lab. Previously, I worked as a software engineer for 3 years developing data infrastructure for processing a massive amount of search keyword logs using Apache Hadoop. I also did research internships for a year and improved the efficiency and reliability of cloud networking at Microsoft Research and other companies.
I received my B.S. in Computer Science from School of Computing of KAIST. I spent one year as an exchange student at UIUC. I was an undergraduate researcher/intern at ANLab (Advanced Networking Lab) of KAIST, Cloud and Mobile Research Group of Microsoft Research Asia, and CSAP (Computer Systems and Platforms Laboratory) of SNU. During my undergraduate years, I was involved in virtualization platform research projects and learned about the core technology of cloud computing hacking the Xen Hypervisor kernel.
