Stanley Shanfield serves as a Distinguished Member of the Technical Staff and Technical Director of Advanced Hardware Development at the Charles Stark Draper Laboratory in Cambridge, Massachusetts, a post he has held since 2003. He is the holder of seven patents and has led teams responsible for inventing and manufacturing new technologies in the fields of semiconductor device fabrication and optical electronics.[1]

Professional Biography

Following his graduation from the University of California, Irvine, where he received a B.S. in Physics in 1977, Stanley Shanfield went on to complete a Doctoral degree from the Massachusetts Institute of Technology (PhD, 1981).

As a newly graduated physicist he became a staff scientist and later senior scientist with Spire Corporation of Bedford, Massachusetts, a manufacturer of renewable energy photovoltaics (1981–1984). In 1985 he joined Raytheon Corporation, serving for seven years as Section Manager for Semiconductors. His work there focused primarily on designs for integrated circuits. In 1992 he was promoted to Laboratory Manager, overseeing the invention of a pseudomorphic high electron mobility transistor. In 1996 he became Manager, Semiconductor Operations, a post he held for three years before a two-year stint as Vice President of Operations at AXSUN Technologies of Bedford, Massachusetts. There he oversaw the development and production of the company's micro-electromechanical (MEM) Fabry-Perot optical filter. As a result of this work Dr. Shanfield was awarded patents for semiconductor processing and control electronics. In 2001 he joined Clarendon Photonics (Newton, Massachusetts) as Director, Packaging & Integration, a post he held until 2003. There he invented a new semiconductor technology for optical add-drop multiplexers. His research at Draper Labs, where he began work in 2003, has resulted in the invention of an ultra-miniature electronics fabrication technology, a newly designed precision MEMS-based[2] gyroscope and associated ASIC (application specific integrated circuit), the development of a miniaturized power source, and the technology and manufacturing process for a semiconductor-based low phase noise oscillator. He currently consults throughout the world as an expert in these matters through Rubin/Anders Scientific, Inc.[3]

Awards and honors

Dr. Shanfield's undergraduate and graduate school careers were marked by several distinctions. Besides attending college on full scholarship, graduating Cum Laude and being elected to Phi Beta Kappa, he won the prestigious U.C. Regents Award for outstanding research project (1975).[4]
