Archibald Samuel Elliott

PhD Student at University of Washington

I'm a PhD student at the Paul G. Allen School at the University of Washington, working in both the PLSE Group and the Sampa Group, advised by Ras Bodik.

I do research into Programming Languages and Compilers, in particular compilation techniques involving Program Synthesis and Domain-Specific Languages.

The rest is on my Publications page or in my CV [PDF].

My Research Projects Publications →

My current research is focussed on Program Synthesis and Solver-aided Compilation. I have also worked on Programming Language design and Solver-aided techniques for circuit design. My previous work has looked at Concurrent and Distributed Systems, and Skeleton-based Parallelism techniques.

Checked C Official Site →

2017: I worked at Microsoft Research on a project to make C Safer, by adding bounds checks to memory accesses. This included design of low-cost dynamic checks as well as bounds inference algorithms.

"Checked C: Making C Safe By Extension" Paper →"Putting the Checks into Checked C" Technical Report →


2016: I tried to use program synthesis techniques to design circuits. It kept almost working, but never enough for a publication.

Erlang meets Idris On Github →

2014–2015: My Bachelor's Dissertation project was producing an Idris to Erlang compiler, and associated libraries for producing verified concurrent programs in Idris that would use Erlang VM features.
