Hello, welcome to my webpage! I am a 5th-year Ph.D. student at Carnegie Mellon University (CMU) School of Computer Science (SCS). I am fortunate to be advised by Dr. Nicolas Christin and work with his team at CyLab (Security and Privacy Institute). My work investigates emerging cybercrime and computer security threats, with a particular focus on the financial domain. I study system- and software-level attacks such as denial-of-service (DoS) and address poisoning on blockchain. I also research societal threats such as fraud, fake accounts, market manipulation, stolen data, and malicious AI endpoints. I am also a recipient of the Nakajima Foundation Fellowship and the Cylab Presidential Fellowship for my doctoral studies.

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