Hi, My Name Is
I am Jin-Dong (Mark) Dong, a final-year CyLab PhD student at Carnegie Mellon University advised by Prof. Nicolas Christin. My research focuses on understanding and protecting users in digital environments through user behavior analytics. By analyzing patterns in how users interact with the systems, I can identify vulnerabilities and predict threats across different domains, such as assessing financial risks in cryptocurrency applications and protecting users from malicious actors online.
Before joining CMU, I received my bachelor’s degree in Computer Science at National Tsing-Hua University. I did research on Neural Architecture Search (NAS) with Prof. Min Sun where we proposed a framework to automatically generate neural networks based on user demands.
Outside of work, I enjoy playing baseball, cooking (the four pastas of Rome have a special place in my heart), and making tea-like coffee. My name in traditional Chinese (zh-TW) is 董晉東
