About

Dominik Winterer is a Ph.D. student advised by Prof. Zhendong Su at ETH Zurich and a member of the AST lab. He is interested in formal methods problems in Programming Languages and Software Engineering. Before his Ph.D. studies, Dominik did undergraduate research in Automated Planning (branch of symbolic AI). Currently he is researching techniques on testing SMT solvers and making them more reliable.

Testing SMT Solvers

Satisfiability Modulo Theory (SMT) solvers are foundational tools for many subareas of computer science, including formal verification, programming languages, and software engineering. Their reliability and robustness are crucial, especially for the safety-critical domains. However, effectively validating SMT solvers has been a longstanding challenge. The goal of Project Yin-Yang is to develop novel, effective, practical methods and techniques to help make SMT solvers more reliable, powerful, and usable. (more details)
