Dr. Nathan Cohen is the CEO of FRACTAL, with a unique knowledge base, innovation knack, and decades of leadership experience. His tenure has given the firm the world-class, state of the art electromagnetic innovations that enhance and enable customers across the full spectrum of wireless and telecom.
He is a physicist and radio astronomer with a background in electromagnetics, fractal geometry, and imaging. A graduate of Brandeis University, he received an M.S. and Ph.D. from Cornell University and has held positions at Harvard, MIT, Cornell, and Boston Universities, Arecibo Observatory, and NASA (JPL and Ames).
He has made substantial contributions to RF and antenna design applications as well as antenna optimization and manufacturing processes, and SETI. He is a pioneer in fractal engineering, holding 48 U.S. utility patents, including ‘source’ patents on fractal antennas, fractal resonators, invisibility cloaks and deflector shields, fractal metamaterials (‘meta-surfaces’) and radiative transfer, fractal batteries, fractal absorbers, flat lenses, and 3D printing.
Dr. Cohen is recognized as a leading world authority on these and related subjects. He has published over 100 technical articles and four books and is a Fellow of the Radio Club of America. He holds the coveted Alfred Grebe Award for Engineering Excellence, and the Technical Achievement Award for invention of fractal antennas. He is a member of IEEE and Managing Editor of the journal FRACTALS.
Dr. Unger is an associate professor of innovation and technology management at Boston University where he specializes in entrepreneurship and technology commercialization in the Department of Administrative Sciences, and is also a member of its Faculty of Photonics. Dr. Unger has been a co-founder, officer, director and/or advisor to various successful companies in the computer science, telecommunications, Internet, photonics, semiconductor and medical fields, including Separation Technologies, Inc.; Paragon Imaging Systems, Inc.; Mercury Computer Systems, Inc. (NASDAQ: MRCY); Bookham Technologies, Inc. (NASDAQ: BKHM); Photo Detection Systems; Color Kinetics, Inc (NASDAQ: CLRK); Barr Associates; Mimeo.com; and BioVentures Investors Ltd.
Earlier in his career, he was co-founder and executive vice president of Kurzweil Computer Products, which ultimately became Xerox Imaging Systems. After this he served as a senior advisor on science and technology in the administration of President Jimmy Carter, where he was involved in the development of programs and legislation to assist promising technology-based companies, in particular Public Law 96-480 the Stevenson-Wydler Technology Innovation Act (establishing technology transfer as a mission of the federal government), Public Law 97-219, the Small Business Innovation Development Act (SBIR) program, and Public Law 96-517, the Bayh-Dole Patent and Trademark Amendment Act. He is also co-founder and chair emeritus of the M.I.T. Enterprise Forum®, an international organization that serves technology based entrepreneurs and the investment community. His work at Kurzweil on consumer involvement in the design of products for the physically disabled is featured as part of the permanent exhibitions of the Smithsonian Institute of the United States.
Dr. Unger holds two bachelor’s degrees from M.I.T., one in engineering and humanities and another in management. He also holds a doctorate in administration and planning from Harvard University.
