Matson is the Direction Leader for both the Materials and Manufacturing Directorate’s MaterialsCharacterization Facility and the ML Mirror Team. His current mirror research is focused on producing materials fora replicated, hybrid/composite mirror system. This includes fabricating both replicated nano-laminate/foilfacesheets from low coefficient of thermal expansion (CTE) materials and nano-sized, negative CTE dispersiods tobe used as CTE tailoring agents for mirror structural substrates and bonding agents. He holds a BS from WrightState University, an MS from the Ohio State University, and a PhD from the University of Dayton.Dr. David H. Mollenhauer’s technical career has largely focused in the area of experimental mechanics. Hereceived a BS in Aerospace Engineering in 1990 from Texas A&M University. As part of the Air Force Palace Knightprogram, he received his MS in Engineering Mechanics from Virginia Tech in 1992, and subsequently earned hisPhD there in 1997. During his tenure at AFRL, he developed a state-of-the-art photomechanics laboratory at theMaterials and Manufacturing Directorate. Using moiré interferometry, he has extensively examined the surfacebehavior of drilled and molded holes in laminated composites; and quantitatively measured the micromechanicalbehavior of model composite systems. The results of his work spawned great interest in a newly developed compositeanalysis method, known as BSAM.
