About me

Welcome to Yizhuo’s corner of the web! I’m a postdoc at Georgia Institute of Technology, working with Taesoo Kim. I gain my PhD in UC, Riverside, under the guidance of Srikanth V. Krishnamurthy and Zhiyun Qian. I also tightly collabrate with Chengyu Song and Manu Sridharan. I’m into all the stuff about computers, especially how operating system works. Coding is the magic for me and I’m keeping improving my ability to wave the wand.

My experience in the computer world:

Security (C/C++)

• Bug detection via program analysis in Linux Kernel
• C/C++ sanitizers
• LLVM frontend, optimization and backend
• Clang plugin and libclang
• Exploits scripts for vulnerability(CVE-2014-3153)
• CTF style exploits

AI/Data Mining/Machine Learning (Python):

• Feature selection
• Cat/Malware Classifier
• Visualzing the distribution of conference from WikiCFP (http://www.wikicfp.com/cfp/)

Software Development (JAVA):

• Instant message applications
• Android App: Voter

Currently I’m doing the program analysis and system security, I already got my name in the Linux patch work, which increases my confidence. This is not only my effort but also the team effort from my advisors and collabrators. I appreciate the patience and help they deliver to me and those mean a lot to me.

The feeling to be a PhD is hard to be summarized in one sentence, sometimes struggling, sometimes exciting, but overall this is the best choice I have made in my life.
