I am a Postdoctoral Research Associate in the Department of Computer Science at the University of Virginia, where I work with Prof. Yixin Sun. I received my Ph.D. and B.S. in Computer Science and Engineering from Seoul National University, under the supervision of Prof. Taekyoung “Ted” Kwon (Seoul National University) and Prof. Taejoong “Tijay” Chung (Virginia Tech).
My research interests lie in the field of network security, with a focus on identifying security issues in network systems and designing practical solutions to address them. As part of my research methodology, I often utilize (large-scale) Internet measurements to gain insights into these systems. My current research focuses on areas including, but not limited to, DNS security and Public Key Infrastructure (PKI)/Transport Layer Security (TLS).
