I teach because I am passionate about learning. Throughout my life, I have been dedicated to deepening my understanding of the world, both professionally and personally. I am fortunate to have a diverse set of both academic and work experiences that blend theory and practice to help me solve problems. I wish to encourage and develop this mix of formality, practicality, and creativity with every student so that they may become better problem solvers, better thinkers, and better people.
My research focuses on programming models, languages, and runtime systems that make it easier to develop high-performance parallel programs. My work to date has led to new approaches and systems to support parallel applications that use globally shared data structures, such as trees and graphs, on parallel systems without physically shared memory.
More recently, I have been researching novel ways to use network offload hardware to accelerate distributed data structures and dynamic load-balancing applications. This work has looked at re-purposing message matching mechanisms, triggered operations, and various network atomic operations to reduce communication and improve performance in parallel applications.
Outside The Classroom
I joined Rhodes in the fall of 2015. Prior to coming to Rhodes, I was at Coastal Carolina University in Myrtle Beach, SC. I grew up in Kalamazoo, Michigan, and went to The Ohio State University in Columbus, Ohio, for my undergraduate studies. After graduating, I was hired by Bell Laboratories, where I worked with the group that built the first Internet systems at AT&T. During my time there I developed systems for Internet networking and security infrastructure. I left Bell Labs to work for several startups focusing on network intrusion detection, machine learning, and video compression and streaming. I loved the excitement and energy of the startup environment, but not so much with the income volatility. I decided to head back to school for my M.S. and Ph.D. in 2004.
I live near the University District in Memphis with my wife and two daughters. Outside the classroom, you can find me in search of a good cup of coffee. Other interests include photography, coral reef keeping, cooking, and perfecting my exasperated sigh.
