The OSA, Columbia Section is a local section of the OSA (the Optical Society), encompassing Oregon and the greater Southwest Washington region. Our section aims to: enhance the understanding of all branches of pure and applied optics, including closely allied optical sciences and technologies; promote interests of its members generally located in Oregon and the greater Southwest Washington region; and encourage cooperation and free exchange of ideas among investigators of optical problems, designers, and manufacturers.

Meet our officers!


Doug Holmgren, President of the OSA, Columbia Section is a Senior Member of the Technical Staff at Applied Materials, where he has designed and developed laser-based manufacturing tools for the semiconductor, display and solar industries for over 15 years. These tools have included semiconductor mask pattern generation systems, laser thermal annealing tools, and precision optical alignment modules. Previously he was a Senior Optical Designer for ESI, where he worked on laser systems for semiconductor memory processing. Prior to working in industry, he was a faculty member at the Institute of Optics in Rochester, NY and the Department of Physics and Astronomy at the University of North Carolina at Chapel Hill for over 12 years, where his research interests were in laser spectroscopy, ophthalmological instrumentation and virtual reality systems. Dr. Holmgren has B.A. degrees in Physics and Applied Physics from Reed College and Oxford University, and M.S. and Ph.D. degrees in Applied Physics from Stanford University.

Ingrid Udd Scheel, Vice President of the OSA, Columbia Section is Vice President of Columbia Gorge Research (CGR). She is responsible for short and long term business strategy and volunteers her time to mentor start ups. She has been involved in fiber optic sensing technology since 2006 and has supported Army Phase I and Phase II SBIRs developing and demonstrating a high speed fiber grating sensor system developed by CGR. She has a Master’s degree in Industrial Engineering and undergraduate degrees in Electrical Engineering and English. Ms. Scheel has coauthored papers for JANNAF conferences and for SPIE. She is also a member of SPIE-the International Society for Optical Engineering and the Society of Women Engineers.

Robert R. Teel, Treasurer of the OSA, Columbia Section provides pro bono counsel and recently incorporated the section as an Oregon public benefit corporation. He works to protect your intellectual property and helps you avoid infringing IP of others. For example, he will advise you on whether to protect your invention by patent and, when appropriate, he will help you develop commercially meaningful U.S. and foreign patent protection strategies. And once Rob secures a patent, he will assist in your efforts to monetize, defend, and enforce it. Should you become concerned about patent infringement, then Rob can advise you on that too—he is an experienced electrical engineer and can show you how to creatively exploit flaws in complex patents that might otherwise frustrate your business objectives. If he finds flaws indicating a patent was improperly granted, then he will provide solutions for invalidating that patent in, e.g., inter partes proceedings before the Patent Trial and Appeal Board of the United States Patent and Trademark Office or litigation before federal courts. He also applies his technical, business, and legal skills in resolving your licensing matters, with a particular emphasis on software and patent licensing. In general, his practice includes U.S. and foreign patent procurement, worldwide patent-portfolio management, patent opinions, product clearance and freedom-to-operate assessments, IP licensing, IP due diligence and transfers, and patent litigation.

Akshit Peer, Secretary of the OSA, Columbia Section, is currently working as an Interconnect Integration Engineer at Intel Corporation, Portland, USA. The development facility, also known as Portland Technology Development, is Intel’s hub for research and development of next generation microprocessors. He is responsible for leading scientific research enabling manufacturing of innovative metal interconnects (back end of line) for Silicon-on-Chip (SOC) products. He received his Ph.D. in Electrical Engineering from Iowa State University in 2017, where his dissertation was primarily focused on simulation, fabrication, and characterization of periodically patterned structures for applications in plasmonics, solar cells, and biomedical devices. Dr. Peer has co authored more than 10 peer-reviewed articles in high impact journals, and he has been cited more than 120 times. He is the recipient of Research Excellence Award from Iowa State University for his outstanding research accomplishments as documented in his dissertation.

Bryan Bolt, Past President of the OSA, Columbia Section is currently Sr. Director of Engineering at Nanometrics Inc. He has worked in the fields of optics and semiconductor capital equipment since 1988 in various engineering and technical management roles with companies including Hardin Optical, Etec Systems, Applied Materials, ESI, Novellus Systems, and Cascade Microtech a FormFactor Company.  Bryan holds a PhD in electrical engineering from the University of North Carolina at Charlotte and is a licensed professional mechanical engineer (P.E.) in the state of Oregon.

Eric Udd, Past President of the OSA, Columbia Section has been deeply involved with fiber optic sensors since 1977 with composite damage assessment since 1984 and in the area of high speed measurements using fiber grating sensors since approximately 1988.

While at McDonnell Douglas from 1977 to 1993 he managed over 20 DoD, NASA and internally funded fiber optic sensor programs. Mr. Udd supported over 30 fiber optic projects at Blue Road Research and directed the growth of the Blue Road Research from one engineer in 1993 to twelve in 2003. In January 2006 he left Blue Road Research to start Columbia Gorge Research (CGR). Mr. Udd founded CGR with the intent of focusing strongly on the objective of moving fiber optic sensor technology to the field quickly and efficiently supporting both end users and developers of the fiber optic technology. He has 54 issued US Patents with more pending on fiber optic technology, has written and or presented more than 200 papers and has chaired over 30 international conferences on fiber optic sensor technology. His books include Field Guide to Fiber Optic Sensors, SPIE Press, 2014, Fiber Optic Sensors: An Introduction for Engineers and Scientists, Wiley, 2nd Edition, 2011, and Fiber Optic Smart Structures, Wiley, 1995. Mr. Udd is a Fellow and has served as a Director of SPIE-the International Society of Optical Engineering. He is a Fellow of the Optical Society of America (OSA), and a member of IEEE and the Laser and Electro-Optic Society (LEOS). Mr. Udd was awarded the Richardson Medal in 2009 by the Optical Society of America for his work on fiber optic sensors and the field of fiber optic smart structures. He has a BS in math and physics from the University of Washington (UW) in Seattle (1974), pursued graduate math studies at UW and has an MSE (Aerospace and Mechanical Science) from Princeton University (1978) where he worked in the Electro-Optics and Applied Physics Group developing a new techniques to measure pressure, temperature and velocity in hypersonic helium flow for NASA Langley.
