I'm Tej Chajed, a recent PhD graduate from the
PDOS group at MIT, advised by Frans
Kaashoek and Nickolai Zeldovich. I work on formal verification of systems
software — I implement systems and prove they do what they're
supposed to.
Before coming to MIT I was at UIUC, where I got undergraduate degrees
in Electrical Engineering and Computer Science.
I'm excited to join the University of
Wisconsin-Madison as an assistant professor in Fall 2023!
Before starting I'll be at VMware Research for a one-year postdoc.
In case you're interested, you can find my research statement,
teaching statement, and CV from my faculty application materials.
Research
Even critical systems software has bugs — for
example, file systems have bugs that occasionally lead to users losing data. My
research aims to write systems software that always does what it's supposed to.
We do this with formal verification: we write a precise specification of what
the system is supposed to do and prove that the implementation meets the
specification. My research has culminated in DaisyNFS, a verified,
concurrent file system that gets good performance. The path to verifying
DaisyNFS involved developing new frameworks and tools, including
Perennial, a framework for reasoning about crash safety and concurrency,
and Goose, a system for connecting the proofs to Go code.
I do a lot of work on Coq-related things, including maintaining a
list of Coq tricks for the
advanced user and contributing to Iris.
I'm a communication Fellow in the EECS
Communication Lab, where I help students with technical communication. If
you're working on something where you think I could help, please reach out! I'm
particularly excited about working on research papers and conference
presentations.

Teaching
I helped create 6.826 (Principles of Computer Systems), a class on systems
verification, and in particular I created the lab assignments. I was a TA for
the class in Fall 2020, Fall 2019, and Fall 2017.
Service
During my PhD I served on a conference program committee for PLDI 2022 and
several artifact evaluation committees (AECs).
How to pronounce my name
"Tej" rhymes with "page", and Chajed is pronounced as written (CHA-jed).
