I am a PhD candidate working at MIT CSAIL advised by Prof. Adam Chlipala.
I worked on a verified compiler from a C-like language called Cito to Bedrock. The Cito language supports expressions, usual control-flow constructs(if, while, etc.), dynamically allocated arrays, and function calls via function pointers. The callee functions can be either Cito functions or Bedrock functions written manually or compiled from other compilers. Hence our compiler supports verified compositional compilation. Cito functions can be recursive (self-recursive and/or mutual-recursive). Everything is written and proved in the Coq proof assistant.
Currently I'm designing and implementing a new language called TiML (Timed ML) which is an ML-like (surprise!) language with a type system containing time complexity annotations. Type will prevent you from calling an O(n^2) function when what you want is an O(n*log(n)) one. You can try it out on its Web interface.
In Summer 2014 I interned at Microsoft Research Cambridge mentored by Georges Gonthier on formalizing matrix differentiation with SSReflect of the Math Component Library. The Coq source code is open-sourced.
In Summer 2016 I interned at Microsoft Research Redmond mentored by Jonathan Protzenko and Nikhil Swamy on the F* language and Project Everest, where I proved the translation from Low*, a first-order fragment of F*, directly to C, for both functional correctness and side-channel attack resilence. The work led to our ICFP 2017 paper Verified Low-Level Programming Embedded in F*.
I got both my Bachelor of Engineering (BE) and Master of Science (MS) degrees from the Department of Computer Science and Technology at Tsinghua University, Beijing, China, in the year 2010 and 2012 respectively. My MS reserach was in the field of computer vision advised by Chinese Academy of Sciences (CAS) Fellow Prof. Bo Zhang.
