Hi! My name is William Liu (刘胥飞). I am a software engineer, as well as a computer scientist and cognitive scientist. I grew up in Madison, Wisconsin but have lived in quite a few other places.
I find that I am generally interested in high performance computing, computer systems with an architecture flavor, theoretical neuroscience, and education. In the future I hope to pursue a PhD in Computer Science to do research in systems for novel applications.
I received my Bachelor’s in Cognitive Science and minor in Computer Science from Carnegie Mellon University. I am currently pursuing my Master’s in Computer Science at The University of Texas at Austin part time.
While pursuing my Master’s degree I am working as a software engineer in Palo Alto, California at a stealth startup (what a weird phrase). We are developing a new chipset and compilation framework which accelerates high data throughput computation architectures, such as modern deep learning models.
Outside of my technical interests I’m also passionate about tricking, esports, anime/animation, video game design, and music. Having a creative outlet helps with being overwhelmed with the vast world of STEM.
If you’d like to reach me, my email is in the footer. I love discussing any interesting projects and ideas or anything really!
I care deeply about improving education at all levels in all places. I have been fortunate to have been a teaching assistant for many courses during my time at CMU, and I hope to continue teaching in the future.

I generally find that I am interested in using mathematical models to analyze computation structures at a fine granularity in order to design better systems. In terms of at which level these systems are implemented at, I haven’t found anything I’m particularly partial towards. I’ve worked at the architecture level, runtime systems level, and compiler level depending on the specifics of the project. I have yet to invest deeply into any of these areas though I do have to admit that instrumenting and implementing at the compiler level has been the least frustrating experience.
I am also gently interested in machine learning research specifically as it pertains to neuro-inspired algorithms. I concentrated my cognitive science degree in theoretical neuroscience and viewing machine learning research through that lens is very interesting to me.
I am extremely fortunate to have been advised by Saugata Ghose since my freshman year at CMU. Most of the development in my technical interests were very positively shaped under his guidance.
I spent the summer after my freshman year doing research full time with my advisor and a couple of other research interns. Since then I have been doing research part time working on virtual memory projects.
