Yong Kiam Tan

About

I am a sixth year graduate student in the Computer Science Department at Carnegie Mellon University.

I am supported by a National Science Scholarship (PhD) from A*STAR, Singapore.

I am a member of the Logical Systems Lab, where I am fortunate to be advised by Prof. André Platzer.

Research

I am interested in proof theory for Differential Dynamic Logic (dL).

In particular, I am studying the continuous fragment of dL, which allows users to syntactically reason about (systems of) ordinary differential equations.

I contribute regularly to the KeYmaera X theorem prover.

I am also a developer of the CakeML compiler, which is formally verified in the HOL4 theorem prover.
