About Me

Hello! My name's Amanda Liu. I'm a second year PhD student at MIT advised by Jonathan Ragan-Kelley and Adam Chlipala. My research interests broadly include type theory, compilers, formal verification, and high-performance systems! I'm interested in using formal methods and programming languages to develop verified, principled methods for writing high-performance systems.

Previously, I was an undergraduate at Columbia University and conducted research under Stephen Edwards and Ronghui Gu on programming languages and formal methods for building hardware and secure smart contract languages, respectively.

Verified Scheduling

We present a Coq framework for optimizing high-performance tensor programs via verified, algebraic rewrites. Paper available.

Closure JavaScript Bounded Generics

Closure is Google's internal optimizing JavaScript compiler. I implemented bounded generic template types within Closure JavaScript's type system.

Rippl Language

Rippl is a toy language with a range of Haskell-inspired features including partial application, type inference, lazy semantics, and list comprehensions.
