Dr. Christopher Lawson is a full Professor of Physics. He teaches College Physics I and II and Geometric Optics, Physical Optics, Optical System Design, and Nonlinear Optics. His research interests are in nonlinear optics and optical sensors. His research specialty is optical sensing and nonlinear optics and he has published over 70 journal articles and 10 books or book chapters in these areas. At UAB, Dr. Lawson has been Principal Investigator (PI) for numerous research grants awarded from the National Science Foundation, the Army Research Office, Army Research Labs, the Air Force Office of Scientific Research, and NASA. 

Dr. Lawson received his B.S. and Ph.D. In Physics at Oklahoma State University, and his M.S. Degree in Physics at the University of Colorado. After receiving his Ph.D., Dr. Lawson worked at Gould Research Laboratories in Rolling Meadows, IL, as a Staff Scientist in the area of fiber optics and fiber optic sensing. This was followed by several years of performing Department of Defense related research in nonlinear optics, fiber optics, optical sensors, and optical system design and prototyping at BDM Corporation in McLean Virginia as a Scientist, Manager, and then Director/Principle Scientist of Optical Sciences.

Administratively, since 2010 Dr. Lawson has served as Executive Director of the Alabama Experimental Program to Stimulate Competitive Research (EPSCoR). Alabama EPSCoR is dedicated to the advancement of economic development via scientific and engineering research through a collaborative effort among the State’s research universities. ALEPSCoR has enjoyed recent success, securing federally funded research expenditures of $17M, $12M, and $12M in 2014, 2015, and 2016 respectively as well as, the writing and submission of a $20M proposal to National Science Foundation funded during 2017, with participation of UAB Physics faculty. Dr. Lawson also serves as Director of the State funded Graduate Research Scholars Program (GRSP), designed to increase the pool of highly trained graduates available to Alabama industry. As of 2017, GRSP support has resulting in 163 Ph.D. and 53 Master's degrees in high technology EPSCoR research areas. Finally, Dr. Lawson serves as Chair of the Coalition of EPSCoR/IDEA States, which assumes a leadership role in coordinating national EPSCoR activities, and he has testified in front of the U.S. House Appropriations Committee on behalf of the EPSCoR Coalition in 2012 and 2013 and provided written expert witness testimony to the "Driving Innovation Through Federal Investments” full U.S. Senate Hearings in April of 2014.

Research Interests

In nonlinear optics, Dr. Lawson’s research interests are directed toward the development and characterization of nonlinear optical (NLO) materials for optical switching and power limiting applications using wavelength tunable Z-scan, degenerate four wave mixing (DFWM), power limiting spectroscopy, and flash photolysis. The focus of this work is to study the relationship between excited state absorption, linear absorption and molecular structure in metal organics using computational modeling supported by a full suite of experimental measurements. His group has demonstrated that unsymmetrical phosphine-substituted bithiophenes exhibit the highest solubility and best blue sensor protection of any material that has been studied in the literature to date. As part of this research, his group has recently developed methods for functionalizing unsymmetrical phosphine-substituted bithiophenes, that will allow it to be incorporated into polymer films and attached to nanoparticles.

In addition, Dr. Lawson is also currently investigating a new class of symmetric and asymmetric oligothiophenes for blue organic light emitting diodes (LED’s) that might be used in flat panel displays. These compounds exhibit strong fluorescence, and can be attached to polymers for use in applications needing thin films.
