Research Projects
since Fall 2021
Lakeroad
Lead Researcher; UW SAMPL Lab/UW PLSE Lab/Real-time Machine Learning
Automatically synthesizing target-specific FPGA dialect implementations for various FPGAs from a functional description of the FPGA architecture using solver-aided programming (via Rosette). Exploring potential FPGA dialects using program rewriting via equality saturation with egg.
since Winter 2020
3LA
Contributor; UW PLSE Lab, w/ colleagues at Princeton and Harvard
Designing a methodology
for verifiably mapping deep learning models to
custom accelerators.
Utilizing Glenside
to expose mappings in workloads.
2020–2022
Lead Researcher; UW SAMPL Lab/Real-time Machine Learning
Designed a pure, binder-free intermediate language for optimizing low-level tensor programs via program rewriting. (See Pure Tensor Program Rewriting via Access Patterns.) Used the language to map computations to custom hardware. (See Specialized Accelerators and Compiler Flows: Replacing Accelerator APIs with a Formal Software/Hardware Interface.)
2018–2020
Lead Researcher; UW SAMPL Lab
Enabled the exploration of new, nontraditional datatypes (i.e., alternatives to IEEE 754 floating point) with an extension to TVM, a deep learning compiler. My qualifying exam project for my Ph.D.
2017–2018
Static Analysis for Processing in Memory Accelerator Design
Master’s Project; PSU Microsystems Design Lab
Given a model of accelerating computation using processing in memory, used LLVM to detect potentially offloadable code sections within workloads.
2014–2018
ThirdEye: Shopping Assistant for the Visually Impaired
Contributor, Lead Researcher; PSU Microsystems Design Lab
Built a wearable system to assist the visually impaired in shopping. My undergraduate research.
Industry Experience
Fall 2021–Summer 2022
Student Researcher (part-time)
Continued my previous work developing a learned cost model for configuring sparse tensor kernels.
Summer 2021
Software Engineering Intern, MLIR
Developed a learned cost model for configuring sparse tensor kernels. In addition, contributed to the MLIR sparse tensor dialect.
Summer 2019
