President & CEO
Mr. Saylor’s career spans over 20 years of emerging technology development and commercialization. Prior to joining SiOnyx, he served as a Vice President of Product Management and Product Marketing for Adobe Systems where he managed Adobe’s award-winning digital video product line. Mr. Saylor joined Adobe from FlashPoint Technology, a digital imaging company he co-founded with a team from Apple Computer, which they built into one of the most prolific licensing firms to serve the consumer digital photography industry. In his early career, Mr. Saylor held a variety of technology management, marketing and engineering roles with Apple, Polaroid and Technicare Corporation. Mr. Saylor holds a BSEE from Northeastern University.
Dr. Christopher Vineis
VP of Engineering
Dr. Vineis has a deep background in semiconductor material and device development. Prior to joining SiOnyx, Dr. Vineis was with Wakonda Technologies, an early-stage company developing flexible thin-film photovoltaics that was ultimately acquired by Solexant (now Siva Power). From 2005 to 2008 Dr. Vineis served as a Member of Technical Staff for MIT Lincoln Laboratory developing InGaAs(P) avalanche photodiode arrays for single-photon time-of-flight imaging. Dr. Vineis started his career with AmberWave Systems as Director of Wafer Technology. AmberWave’s strained silicon technology for high speed/low power CMOS was licensed or utilized by a wide range of semiconductor companies including Intel, UMC, Applied Materials, LG Siltron and SUMCO. Dr. Vineis has a Ph.D. from Massachusetts Institute of Technology and a B.S.E. from the University of Pennsylvania, both in Materials Science and Engineering.
Dr. Martin Pralle
VP of Business Development
In his role as VP of Business Development for SiOnyx, Dr. Pralle is helping to deliver next generation silicon-based optoelectronic technologies to military and other government applications. Prior to joining the Company, Dr. Pralle served as General Manager of the ICx Technologies Photonics business unit. As VP of Engineering at ICx Technologies, he developed photonic crystal MEMS infrared emitter and sensor technology that was deployed to solve critical combat identification needs in the thermal imaging bands. Dr. Pralle holds a PhD from the University of Illinois at Urbana-Champaign and a BS from Cornell University, both in Materials Science and Engineering.
Dr. James Carey
Principal Scientist & Co-Founder
Dr. Carey is an expert in optical physics and the interaction of materials with ultrashort laser pulses. Dr. Carey played a key role in the discovery of the unique optoelectronic properties of pulsed laser microstructured silicon, the study of which formed the basis for his Ph.D. in Applied Physics from Harvard and led to the founding of SiOnyx. Dr. Carey is an author of over 20 papers and conference proceedings, a named inventor on 12 US and international patents, and has presented at numerous international conferences. Dr. Carey also holds a BSE from the University of Michigan.
