Ariel E. Kellison


I am a PhD candidate in computer science at Cornell University, co-advised by David Bindel (Cornell) and Andrew Appel (Princeton). My current research primarily focuses on applying techniques from formal methods and programming languages to reason about the accuracy and correctness of numerical programs. As part of the VeriNum research group, I develop and maintain the VCFloat and LAProof libraries for the Coq Proof Assistant.
