Jimmy Romanos

Dr. Romanos is an assistant professor of Physics in the Department of Natural Sciences. He joined LAU in Fall 2013. He received an MS in Physics, an MS in Mechanical and Aerospace Engineering, and a Ph.D. in Physics from the University of Missouri.  Before returning to Lebanon, Dr. Romanos worked in the oil and gas industry in Houston, Texas, where he led a team of researchers in developing sorbent materials for the transport and storage of natural gas.

His research interests are interdisciplinary and lie in the fields of condensed matter physics, materials science, nanotechnology, and energy storage.  His current research focuses on the development of novel nanomaterials for various applications:   

• Natural gas capture, storage, and transport for the upstream and downstream sectors of the petroleum industry.   
• Gas separation by physical adsorption. 
• On-board storage of hydrogen for fuel-cell vehicles. 
• Carbon dioxide capture and sequestration.
• Lead-free ceramics.

Dr. Romanos’s research has been patented, published in renowned peer-reviewed journals, and presented at international conferences. He is an active member of the Materials Research Society (MRS), the American Society of Mechanical Engineers (ASME), the American Chemical Society (ACS), and the American Physical Society (APS).
