Optel, Inc., USA
Term: 1/1/2015-31/12/2017

Jay Eastman received his B.S. (1970) and Ph.D. (1974) from The Institute of Optics at the University of Rochester. Following completion of his degrees he became the manager of engineering in the Optics Group at Spectra Physics in Mountain View, California. From there he joined the staff of the Laboratory for Laser Energetics at the University of Rochester, progressing from staff engineer to Project Manager for the construction of the 24 beam Omega Laser Fusion System. He finally served as the Director of the Laboratory after the departure of its founding director.

Dr. Eastman has subsequently formed four start-up companies, with three of them having strong optics and photonics technology bases. The first was Optel Systems Inc., (subsequently acquired by PSC, Inc.) which developed the first hand-held laser diode-based bar code scanners in the world. During the 1990’s the company became a recognized leader in field of bar code scanning. Next was Lucid, Inc., a pioneer in the development of in-vivo confocal microscopy for the diagnosis of skin cancer. The confocal imagers, called VivaScopes, have been used by medical researchers around the world for research and clinical diagnosis of skin cancers, resulting in over 350 peer-reviewed publications in various medical journals and several books on the use of confocal microscopy in dermatology. Eastman is now involved as a co-founder in two more start-up medical companies, one of which is heavily based on optical technology. As a consequence of his work in these companies, he is a named inventor on 44 issued U.S. patents.

In addition to his entrepreneurial pursuits, Dr. Eastman has served as an adjunct professor at the Institute of Optics over the years since he received his Ph.D., periodically teaching courses in optical fabrication, optical thin films, product development and entrepreneurism. Dr. Eastman’s honors, awards and professional contributions and achievements include: member of the National Academy of Science’s Board of Assessment of NIST Programs, Panel for Physics (2000-2002); Herbert Vanden Brul Entrepreneur of the Year Award (1996-1997); The Optical Society: Engineering Excellence Award (1994), Board of Directors (1984-1988), Chair of the Technical Council; Rochester Engineering Society - Engineer of the Year (1997); Rochester Museum and Science Center - Distinguished Lecturer; Rochester Optical Society: Honorary Member (1992) and President; University of Rochester SMPTE Fellow, (1972-1973), and Society of Photo-Optical Instrumentation Engineers - Board of Governors.

Inrad Optics, USA
Term: 1/1/2015-31/12/2017

Amy Eskilson has served as President and Chief Executive Officer of Inrad Optics, located in Northvale, NJ, since October 2012. Inrad Optics is a manufacturer of exceptional quality crystal materials, crystal devices and high precision optical components. As the leader of a small publicly-held company, Ms. Eskilson has a responsibility to both the business and to its shareholders. She also embraces her role as the company’s Chief Culture Officer, and as such works to mentor younger employees as well as challenge and excite longtime contributors. A strong advocate for localized manufacturing, Amy is focused on building an organization that is competitive and profitable while delivering products with extraordinary optical specifications.

Ms. Eskilson joined Inrad Optics in early 2011 as VP Sales and Marketing, charged with leading the sales team and building a market presence for Photonics Product Group, an umbrella company for the original Inrad, Laser Optics and MRC Precision Metal Optics brands. The multiple brand names had led to confusion in the industry and Amy executed an effort to rename and rebrand the organization. In January 2012 the business officially became Inrad Optics and launched a new website and marketing push concurrent with that name change.

In 2002 Ms. Eskilson’s role at Thorlabs became more strategic and outward facing. As Director of Business Development and a key member of the Thorlabs senior team, Amy’s work focused on three main areas – acquisitions, building the Thorlabs strategic partner companies, and contracts, including licensing agreements, real estate matters, and supply agreements in partnership with outside counsel.

Amy is an engaged advocate for photonics, championing the field from the importance of basic research through the downstream commercialization of photonics technologies. Ms. Eskilson has also been active in several photonics start-up companies. She was a minority partner in optics and crystals manufacturer Nova Phase, Inc. and Menlo Systems Inc. (U.S. spin-out of Menlo Systems GmbH), both based in Newton, NJ. Amy currently serves as a member of the Board and minority partner in Idesta Quantum Electronics, Newton, NJ.

A member of OSA and SPIE, Ms. Eskilson has served on the OSA Public Policy Committee, the CLEO Joint Council on Applications, and as former chair of the CLEO Exhibitor Advisory Committee. She was recently profiled for the 2014-2015 SPIE “Women in Optics” Daily Planner publication.

Prior to discovering optics and photonics in 1992, Amy received her BA degree in Communications from Montclair State University in 1987 and spent several years in New York at McCann-Erickson, the worldwide advertising group.
