Service at Utah
For honors students: I serve as the Department Honors Liaison for the Kahlert School of Computing. If you are an honors student (interested in) pursuing a research- or capstone-based honors thesis,
this document provides a comprehensive overview of requirements.
For Utah graduate students: I founded and organize the
Graduate Research Symposium: a yearly Spring event featuring lightning talks by graduate students. If you are a Utah graduate student interested in giving a talk, please connect with me.
