Bio 微信图片_20230814214647

I am an incoming PhD student at UC Berkeley in SkyLab and the last-year undergraduate student in the ACM honor class of Shanghai Jiaotong University, majoring in computer science and technology. I am interested in machine learning systems and high-performance computing systems (to be more detailed maybe distributed systems for large ML model training, and develop tailored abstractions for unique ML computational patterns to achieve higher performance).

Currently, I am also collaborating with Prof.Jinyang Li in NYU on a project related to scale up GNN training. In SJTU, I am supervised by Prof. Quan Chen at EPCC.

I like to communicate with different people, so you can feel free to contact me via email wechat:15858459091 or yichuanwang0324 or twitter If you are willing to know more details, you can see my CV here. If you are interested in my motivation, you can also take a look at my SoP for application.

Selected Projects


A system that can build its own scene and track the refraction and reflection of light in it. Several compilation-related optimizations were undertaken to enhance the overall performance.

Compiler for Mx* Language

Using the technology of ANTLR, semantic checking, code generation, and optimization to develop a compiler that compiles C-and-Java-like language to RV32I Assembly from scratch.

RISC-V CPU Implemented in Verilog RTL

Designed a RISC-V CPU with Write Buffer, ICache, DCache, and Branch Prediction. Supports RV32I instruction set (2.1-2.6 in RISC-V User Manual). Used Vivado to generate bitstream and program the Basys3 FPGA board.

Ticket System

Designed a train ticket system with multi-user support and privilege management. I implemented the backend and built a Bplustree storage. All used C++ STL data structures are from scratch (including map, and queue).
