Sajjad Bigham

Associate Professor

Dr. Sajjad Bigham is an associate professor in the Department of Mechanical and Aerospace Engineering at North Carolina State University. Before joining NC State, he was the Lou and Herbert Wacker Associate Professor in the Department of Mechanical Engineering–Engineering Mechanics at Michigan Tech University. He received his Ph.D. degree in Mechanical Engineering from the University of Florida. He directs the Energy-X Lab (Energy eXploration Laboratory) at NC State University.

He is a heat transfer and energy systems specialist interested in scientific and engineering challenges at the intersection of thermal fluid, material, and energy sciences. Our lab, Energy-X (, is focused on understanding the fundamental transport science of important energy carriers at micro, nano, and molecular scales. We design, fabricate, and examine various meso-, micro-, and nano-devices/systems to understand their underlying physics and explore new technologies and performance breakthroughs.

Energy-X mission: Energy-X is a research group specializing in energy science and technology. The increasing global demand for energy has stimulated intense research on energy conversion and storage systems. The mission of our lab is to improve energy efficiency, reliability, and economy of the process, component, or system X; with X being our target technological area which spans from the energy sector to defense and environmental applications.
