Background
Prior to joining ORNL, David obtained his Ph.D. in Computer Science from The University of Tennessee, Knoxville. His Ph.D. research focused on using low-level metrics for performance analysis of distributed applications. He previously worked as a Research Assistant at the Innovative Computing Laboratory at the University of Tennessee under Dr. Jack Dongarra and Dr. George Bosilca. David’s research at ORNL involves performance analysis of OLCF applications and preparing the ExaBiome project for Frontier.
Outside of work, David enjoys playing video games, watching movies and TV shows, reading novels, playing tennis and badminton, and musical whistling. David has participated in two different international whistling competitions, one in Kawasaki, Japan, and one in Los Angeles California. He achieved second place in his division in The Masters of Musical Whistling competition in 2019. He is also one of the founders of the International Whistlers Guild formed this year.
