Germany where he gained the Dipl.-Ing. Feinwerktechnik FH dip-loma. He then joined company TEMIC in Nuremberg until 1996, doing R&D for optoelectronic sensors in automotive applications (car alarm systems and rain sensors). His background in optics led him to join company OPTIS in 1996. First in charge of software support, Günther then worked as an Application Engineer, then Head of Application Engineering. Today he is Chief Technology Officer, based in Toulon, France and covering subsidiaries in the US, Germany, China and Japan. He speaks German, English, and French. Günther lives near Toulon with his wife and two children.

Jake Jacobsen received his Bachelor’s degree in physics from the University of North Dakota in 1985

and a Master’s degree in physics from Montana State University in 1987 after which he served as a commissioned officer in the U.S. Army. In 1997 he received a Ph.D. in optical engineering from the University of Arizona. After graduation he worked as an optical engineer for Nikon Corporation in the optical testing group in Tokyo until 2000. From 2000 to 2001 he was a senior optical engineer for the Agere Corporation designing fiber amplifier components. In 2001 he joined Optical Research Associates as a customer support engineer for CODE V. From 2004 to 2010 he was the LightTools Product Manager. In 2010 he became the Senior Technical Marketing Manager for both CODE V and LightTools.

John Koshel received his BS and PhD in Optics from The Institute of Optics, University of Rochester.

Since graduating with his doctorate in 1996 he has worked at NIST, Rose-Hulman Inst. Of Technology, Spectrum Astro, and Lambda Research Corp. He is currently in charge of the consul-ting group at Photon Engineering and teaches and leads research at the College of Optical Sciences at the Univ. of Arizona. At Optical

Michael Gauvin has over 25 years experience in the optical and illumination design fields and reducing

stray light in multiple space borne telescopes. Mr. Gauvin is best known for his work on the Bionix Ear Curette which won an MDEA award in 2005.

Mr. Gauvin holds a B.S. in System Engineering, University of Arizona, 1982 and has taken graduate classes at the Optical Science College, University of Arizona 1983 –1985.

Prior to founding Brandenburg GmbH, Wilhelm Brandenburg worked for Hella KG Hueck & Co. for

17 years. During this period he became director of the department for „technical software development“. Later he became director of the Lighting Laboratory and was responsible for headlamp development worldwide. In 1998 Wilhelm Brandenburg founded Brandenburg GmbH. Brandenburg GmbH develops and distri-butes the software LucidShape and LucidDrive. In addition, the company does software and optical engineering work for several prominent companies in the lighting industry.

Alexander von Hoffmann received the Dipl.-Ing. degree in electrical engineering in 1998 from the

Darmstadt University of Technology and the Dr.-Ing. degree in 2003 from the Ilmenau University of Technology. He has been working from 1998 to 2006 in VOLKSWAGENs Lighting Develop-ment Department. Since October 2006 he is professor for mecha-tronics at the University of Applied Sciences Nuremberg. Current research concentrates on optical and thermal simulation methods for LED Applications.

Kevin Garcia has more than 25 years of optical- engineering experience in the commercial, indus trial,

and aerospace markets on a wide range of optical-design and analysis projects. From automotive-lighting to zoom- lens designs, Dr. Garcia has supported engineering projects at companies large and small and as diverse as Eastman Kodak, TRW, Xerox Corpo-ration, and BRO. He has previously held Senior Optical Engineer and Director of Engineering positions at BRO. As CEO, Dr. Garcia leads the company’s engineering, software, and training teams to meet the needs of clients in 35 countries. His technical and managerial capabilities, his familiarity with contract-engineering processes, and his ability to see the busi ness value of technolo-gies serves clients moving their creative ideas through the design and manufacturing process.

Sciences he teaches a project-based course on illumination engi-neering for both undergraduate and graduate students. He is the chair of the Fabrication, Design and Instrumentation Division of the OSA, and he is the chair elect for the OSA Board of Meetings. He is an assistant editor for the Energy Express part of OSA’s Optics Express. He is the chair of SPIE’s Novel Optical System Design and Optimization conference held at Optics and Photonics and is a member of SPIE’s Audit Committee. He is an author for SPIE’s Illumination Field Guide and a chapter in the Handbook of Optics on Lighting. He has just com pleted the manuscript for a book entitled Illumination Engineering: Design with Nonimaging Optics. He works in the field of illumination engineering, with focus at this time in the areas of solid-state lighting, optimization and solar concentrators.

1st International Light Simulation Symposium7th / 8th of March 2012 | Nuremberg, Germany

ILISIS 2012Throughout the past few years light simulation has been a fast growing method to accelerate the development process of components for the lighting industry. Most companies that have used light simulation in the development process are working not only with one, but with several different light simulation products. Independent of the simulation software used, the fundamental questions are virtually the same: how to realistically model the world?

International Light Simulation Symposium (ILISIS) has the intention to bring together the light simulation software developers and their users. It is an opportunity for a scientific exchange about experiences in modelling optical behavior.

LOCATIONThe ILISIS Symposium will take place in Nuremberg, Germany. Depending on the number of participants we will select an appropriate location. The final location will be published at www.ilisis.com.
