Dylan Chapp is a Research Associate advised by Dr. Michela Taufer at the Department of Electrical Engineering and Computer Science at the University of Tennessee, Knoxville, Ph.D. Student at the University of Delaware, and collaborator with Lawrence Livermore National Laboratory advised by Dr. Kento Sato and Dong H. Ahn. Chapp earned his MS in Computer Science from the University of Delaware in 2017 and BS in Mathematics from the University of Delaware in 2014. Chapp's research interests in high performance computing include the characterization of runtime nondeterminism in parallel applications through large-scale graph analytics, computational reproducibility, and tools for achieving correctness in HPC software. Specifically, he works on modeling the relationship between runtime nondeterminism of MPI applications and the cost of deploying debugging tools against them. He is a member of the IEEE and ACM.
