+**Title:** Types and Metaprogramming for Correct, Safe, and Performant Software Systems
+
+**Abstract:** In this talk, I will present some novel directions to build correct, safe, and performant software systems using programming languages and metaprogramming techniques. In the first part of the talk, I will present reachability type systems, a family of static type systems to track sharing, separation, and side effects in higher-order imperative programs. Reachability types lead to a smooth combination of Rust-style ownership types with higher-level programming abstractions (such as first-class functions). In the second part, I will discuss how metaprogramming techniques can help build correct, flexible, and performant program analyzers. I will present GenSym, a parallel symbolic-execution compiler that is derived from a high-level definitional symbolic interpreter using program generation techniques. GenSym generates code in continuation-passing style to perform parallel symbolic execution of LLVM IR programs, and significantly outperforms similar state-of-the-art tools. The talk also covers my future research plan to apply reachability types in designing languages for quantum computing.

+**Bio:** Guannan Wei is a postdoctoral researcher at Purdue University. He will join Tufts University as a tenure-track assistant professor in Fall 2025. His research interests lie in programming languages and software engineering. His contributions have been published in flagship programming languages and software engineering venues, such as POPL, OOPSLA, ICFP, ECOOP, ICSE, and ESEC/FSE. Guannan received his PhD degree (2023) in Computer Science from Purdue University, advised by Tiark Rompf. More of Guannan’s work can be found at https://continuation.passing.style.
