Lloyd received his Ph.D. in Systems Engineering from the University of Pennsylvania in 1992. He worked with us as a Postdoctoral Fellow in the Stewart School of Industrial and Systems Engineering from 1992 to 1993, and as an Assistant Professor from 1993 to 1999. As a faculty member, Clarke was extremely dedicated to helping students, and was a great mentor and role model, particularly for African American students. Lloyd's research was in applied optimization and his specialty was developing software that embodied innovative optimization concepts. Lloyd left Georgia Tech to learn more about logistics operations at Schneider National and then joined ILOG in 2000 to pursue his love of optimization software development.

An avid cyclist, gardener, and photographer, Lloyd was a native of Belize. He lived with his wife Sherol and their daughter Elta in Hagerstown, Md. He is remembered for his kindness, generosity, and his smile. Lloyd was a delightful person who never failed to raise our spirits.
