My courses focus on the design of computer systems, encompassing low-level operating system details, programming languages and compilers, and distributed systems consisting of thousands of machines. I teach students how to build real working systems from end-to-end, taking into account not just performance, but also reliability, completeness, usability, maintainability, and beauty.

Recent courses taught at the University of Notre Dame include:
