D. Brian Larkins

Assistant Professor of Mathematics and Computer Science


I teach because I love to learn and love to be around learners. Early in my career, I volunteered to teach high school students basic computer science concepts through an outreach program hosted by AT&T Bell Labs. Over the eight years that I gave my time and energy to this program, I found that teaching deepened my personal understanding of the field and also opened up new worlds to my students. Having a background in both industry and academia gives me a unique perspective on the field of computer science -- one which I try to bring into every class that I teach at Rhodes.


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.

Most recently, I have been researching novel techniques for implementing parallel data structures such as a distributed key/value store. This library provides a single, global view of the distributed data, while offloading much of the runtime work onto the network interface hardware. My goal is to make it easy to write software for use on large-scale parallel systems without sacrificing performance.

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.
