James H Clark, III is the chief mechanical engineer at the Navy Precision Optical Interferometer (NPOI) in Flagstaff, Arizona. He received his M.S. in mechanical engineering from Northern Arizona University (NAU) in 2006 and is currently a PhD. student in the same department. Prior to joining NPOI in 1990, he worked at Optelecom, Inc. on fiber optic payout systems for guided missiles, tethered terrestrial and unmanned underwater vehicles, and sonobuoys. His research interests include solid mechanics and optomechanical systems. Some of his past research projects include the development of analytical methods to predict optical fiber strain in wound composite payout bobbins under thermal loading, the deflection and compliance sensitivities of mounted optical mirrors under thermal and gravity loading, and vibrational analysis of large aperture fast steering mirror structures. Since 2005, he has worked closely with NAU in a variety of applications related to the NPOI, and currently teaches classes as a part-time instructor in mechanical engineering and sponsors senior engineering capstone projects. He has disseminated the results of his research activities in archival journals as well as technical conferences.
