Michelle X. Yeo

I'm a postdoctoral researcher at the department of Computer Science at the National University of Singapore (with Seth Gilbert). Previously I completed my PhD at the Institute of Science and Technology Austria where I was fortunate to be supervised by Krzysztof Pietrzak. Prior to that I completed my undergraduate and masters at the University of Chicago and University College London respectively.

My research interests lie in the intersection between blockchain security and game theory. In particular, I adopt a two-pronged approach to blockchain security analysis: on one hand I aim to construct efficient and provably secure (in the rational model) blockchain and Layer 2 protocols, and on the other hand I also enjoy coming up with novel attacks (with analysis) that break existing protocols. Additionally, I'm also interested in blockchain scalability, especially optimisation problems in the domain of payment channel networks.
