number of academic, government, and industrial boards as a technical
manager. He served on the National Research Council (NRC) Committee on
Optical Science and Engineering and is a National Associate of the National
Academies.
Dr. Pengfei Wu, Chief Scientist

Dr. Pengfei Wu, Ph.D., received his PhD degree in Optics in 1996 from Nankai
Univeristy. In his PhD study, he initiated a biphotonic holographic technique
using polymer which was invited by SPIE Holography newsletters. From 1996
to 1998, he was a scientist at the Institute of Physics, Chinese Academy of
Sciences, engaged in theoretical and experimental work on Raman spectrum,
optical nonlinearity and time-resolved optical techniques. He also worked on
four wave mixing, phase conjugation, self-diffraction, two beam coupling,
electro-optical effects, optical imaging & processing, and optical bistability.
From 1998 to 2005 he was a senior research fellow at Physics Department,
Univ of Massachusetts (Boston, MA), worked with Laser & Chemical
Laboratories, US Army Soldier Systems Center (Natick, MA), on many Army
supported R&D projects, such as, 1) light scattering and diffraction with
aligned nanotubes; 2) ultraslow light using coherent population; 3) power
limiting, laser eye & sensor protection using ultrafast nonlinear effects; 4)
optical switching and spatial light modulation using nano-organic thin films; 5)
nonvolatile bi-photonic holographic data storage using polymer films; 6)
nonlinear waveguides, optical sensors and photonics fiber devices; 7) optical
imaging & information processing; 8) medical image enhancement & analysis
using optoelectronic hybrid Fourier systems and nonlinear optical techniques.
During this period, he also worked with Ocean Nanotech and Cape Cod
Research companies, as well as other universities on various research
projects. From 2005-2011, he has worked with New Span Opto-Technology
and Agiltron, Inc. on many government-supported research projects. He was a
leading performer in the research teams and won many SBIR/STTR research
projects. He has worked as Principal Investigators with both Phase I and II
projects supported by NSF, US Army, Air Force, and Navy. Dr. Wu joined
Crystal Research, Inc. in Oct. 2011. Dr. Wu has published over 50 papers in
peer reviewed journals such as Phys. Rev. Lett., Appl. Phys. Lett., Opt. Lett.,
and Nano Lett. He also hold 4 pending US patents and one of his work won
one of Nano 50 Awards. His work has also been highlighted by magazines
such as Nature, Physics Review Focus, and CERN Courier.
