Hello, welcome to my webpage! I am a 5th-year Ph.D. candidate at Carnegie Mellon University (CMU) School of Computer Science (SCS). I am fortunate to be advised by Professor Nicolas Christin and affiliated at CyLab (Security and Privacy Institute). My work develops large-scale measurement infrastructure to study cybercrime and computer security attacks in the wild, particularly those targeting financial systems. The examples include denial-of-service (DoS) (SIGMETRICS’25), address poisoning (USENIX Security’25), fake accounts and fraud (WWW’24, WWW’23), and malicious chatbots (ICWSM’26). I am a recipient of the Nakajima Foundation Fellowship and the CyLab Presidential Fellowship for my doctoral studies.

Previously, I was a research assistant at Cyber Civilization Research Center (CCRC) under Dr. David J. Farber in 2021 and was a research visitor at the University of Cambridge, Department of Computer Science and Technology under Professor Alice Hutchings in 2025.
