%------About Me-------
\section{About Me}

I am currently working as a \textbf{post doctoral researcher} at \textbf{Computer Security Lab} of \textbf{Seoul National University}. I received \textbf{Ph.D} at \textbf{Computer Security Lab}, advised by professor \textbf{Byoungyoung Lee} from 2019 to 2023. Before then, I studied at \textbf{multimedia wireless network lab}, advised by professor \textbf{Sunghyun Choi} since 2017 until 2019.

I'm interested in the issues of \textbf{system security} in general, but I focused on two topics during my Ph.D: \textbf{fuzzing}, and \textbf{confidential computing}. As a research, I developed an RTL fuzzer for RISC-V CPUs, named \textbf{DifuzzRTL}, and presented it at \textbf{IEEE S\&P 2021}. In the following research, I developed the first RTL fuzzer that finds transient execution vulnerabilities, named \textbf{SpecDoctor}, presenting it at \textbf{ACM CCS 2022}. After that, I moved to work on \textbf{confidential computing}, especially applying it to solve the issues of data privacy and sovereighty in machine learning. Accordingly, I developed \textbf{DLBox} (will be presented at \textbf{NDSS 2025}), which systematically protects the data from untrusted machine learners. In addition, I have guided several research projects about cloud security, such as \textbf{TeeMate} (i.e., efficient confidential serverless computing), and \textbf{Laputa} (i.e., secure policy enforcement in Spark), etc. Currently, I am working on virtualization (i.e., KVM), emulating TDX machines.

As above, \textbf{I have studied the topics in system security across the various fields, and I am always open to new security issues}. Besides, I generally like programming and solving the problems on my own, so I developed \textbf{MumeParrot}, which automatically trades stocks for me, and \textbf{Kandl}, which is a ChatGPT based course recommendation bot.
