Taro Tsuchiya
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 research aims to enhance the safety and security of financial services through the lens of computer security. I study system- and software-level attacks, including denial-of-service and address poisoning on blockchain, while also addressing societal threats such as Sybil attacks, spam, toxicity, and market manipulation. I am also a recipient of the Nakajima Foundation 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.
