People
Duality Lab is a software-engineering research group at Purdue University. Our work is carried out by graduate and undergraduate researchers working across the lab’s research programs.
Mentorship is a central part of the lab. Graduate researchers develop independent research programs, while undergraduate researchers participate through sustained research teams, senior design, independent study, SURF, REU, and related programs.
