Dr. Peili Chen received his PhD from the University of Hull, UK, MS from the Institute of Semiconductors, Chinese Academy of Sciences, and BS from the University of Science and Technology of China. Dr. Chen authored and coauthored numerous peer reviewed journal papers and patents. Dr. Chen was a principal engineer at Nortel/Coretek, developing vertical cavity lasers for telecommunication. He was also a research scientist at Photonics Industries International on Long Island, NY and developed high power diode pumped solid state lasers. He was a key member of R&D team at Ahura Scientific where he developed external cavity lasers and spectrometers used in Ahura’s handheld Raman analyzers, as well as optical engines of miniature FTIR spectrometers. Those instruments became successful commercial products and led to the acquisition by Thermo-Fisher Scientific. As co-founder and principal scientist at Pendar Medical, he applied Raman and other spectroscopic techniques to clinical measurements, a role he continues.
