Dr. Seng’s expertise involves nondestructive test and evaluation of different high dynamic systems with transient features as fast as a few nanoseconds. Including railguns, pulsed power systems, Hopkinson bars, explosives and body armor. He has worked with optical phenomena such as the electro optic effect and photo elastic effect, both of which he has used in fiber optic sensing applications. He has experience interrogating fiber optic systems with wavelength division multiplexing (WDM), optical time domain reflectometry (OTDR), and optical frequency domain reflectometry (OFDR), heterodyne and homodyne interferometry systems. Dr. Seng also has experience working with semiconductors and cleanroom fabrication, high power circuit design, and algorithms. He has extensively programmed with C, Java, MATLAB, and Python, working with graphic designers to come up with fully functional designs for applications to be delivered to customers.

Prior to joining Exponent, Dr. Seng was a consultant to Traverse Solutions and Instrumentation, where he helped develop systems and algorithms for photon Doppler velocimetry (PDV). Prior to this he was a research assistant at Brigham Young University (BYU), where he received his doctoral degree in 2018. His thesis involved developing an in-situ method for determining the back face deformation (BFD) of body armor with fiber Bragg gratings (FBG)s. He successfully worked with a team of electrical and mechanical engineers via collaboration between BYU and North Carolina State University (NCSU) to develop a sensing layer and algorithm that allowed for conversion of strain from FBGs under impact into BFD over time.

Dr. Seng has worked with single mode, multi-mode, PM (PANDA), side polished PANDA, and D-fiber. He has designed fiber optic systems using WDM, fiber optic splitters, tunable wavelength filters, erbium doped fiber amplifiers (EDFA), fiber optic phase modulators, fiber optic amplitude modulators, fiber optic polarizers, graded index (GRIN) lenses, fiber optic power taps, variable optical attenuators, and more. He has experience using a variety of optical test equipment such as amplified spontaneous emission (ASE), lasers (fixed, tuned, and swept sources), optical spectrum analyzers (OSA), and photodetectors for high speed or high power purposes. Dr. Seng has developed methods for improving signal to noise ratios in fiber optic networks by over 100 times, simultaneously reducing optical strain noise, optical interferometric noise and RF noise imposed on receivers, while boosting the electro optic effect, allowing the fiber optic network to operate in a previously inoperable harsh environment.

Dr. Seng has been a teaching assistant for Brigham Young University’s introduction to circuits lab, electronics for non-majors lab, and introduction to circuits course. He has also completed internships at Northrop Grumman, ATL Technologies, and Braven.
