About

I am a graduate student in the UNC-Chapel Hill Real-Time Systems Group under Professor James H. Anderson. My primary research focus is on extending the soft real-time optimality properties of Earliest-Deadline-First (EDF) schedulers.

Teaching

I am tentatively teaching an undergraduate real-time systems course in Fall 2021. The course webpage is under construction. A webpage for a prior version of this course taught by Catherine Nemitz is available here.
