About Me

Hi! I am a Ph.D. student in the School of Computer Science & Engineering at the University of Washington . I am a part of the databases and programming languages research groups, where I focus on developing tools for verified lifting; a novel synthesis and verification based technique for source-to-source translation of programs. I am advised by Alvin Cheung.

Research Interests

I am interested in building programming systems using synthesis, especially for high-performance computing and big-data management.


MetaLift active

MetaLift is a framework for building compilers that target domain-specific languages (DSLs). Unlike traditional syntax-driven compilers, which consists of rules that recognize patterns in the input code and translate them into the target language, MetaLift uses verified lifting to search for possible candidate programs in the target language that the given input can be translated to. This frees the developer from the need to devise, check, and maintain those pesky syntax-driven rules!

HALO active

HALO is a compiler that uses Verified Lifting (a combination of synthesis and verification) to automatically retarget legacy image processing stencils to Halide. I am working on this project as part of my internship at Adobe under Shoaib Kamil.

Casper complete

Casper is a compiler that uses Verified Lifting (a combination of synthesis and verification) to automatically retarget sequential Java code to MapReduce frameworks such as Apache Spark.

GraSSP complete

A novel approach for automatic parallelization of single-pass array-processing programs with possible data-dependencies. This project is lead by Grigory Fedyukovich.
