Research
I design novel hardware architectures to build more efficient abstractions in programming languages, while maintaining a productive and safe interface for programmers. I also write and optimize high-performance systems software, such as garbage collectors, virtual machines, and distributed ML training libraries, supported by the performance analysis tools and methodology I develop. You can learn more about my research here.
