Zachary Tatlock

Zachary Tatlock is an Associate Professor at the Paul G. Allen School of Computer Science & Engineering, University of Washington. He leads the UW PLSE research group and focuses on making programming languages and compilers more accessible through formal verification and practical tool development.

• Current affiliations: University of Washington (Paul G. Allen School)
• Academic rank: Associate Professor

His research spans programming languages, compiler optimization, and formal verification, with recent work on:

• E-Graphs and equality saturation for program synthesis
• Floating-point error analysis and accuracy optimization
• Accessible web layout verification using formal logic
• Hardware-software co-design for compiler generation

His recent publications demonstrate expertise in both theoretical foundations (congruence closure proofs, anti-unification) and practical implementations (Odyssey tool for FP rewriting, Titanic framework for number systems analysis). Collaborations span institutions like Adobe and involve rigorous formal verification in Coq and CakeML.
