Eric L. Buckland, Director, President and Chief Executive Officer at Bioptigen has lead technology development, strategic planning, and commercial operations at major global optics companies since 1985. Dr. Buckland was a key executive in Corning Incorporated's Photonics Technologies Division from 1999-2003, and was instrumental in the development of a new division formed to commercialize optical switching technologies for the all-optical network. Dr. Buckland earned his B.S summa cum laude and M.S in physics from North Carolina State University. He earned a Ph.D. in optics from the University of Rochester. He has been awarded 6 patents and has written more than 30 publications and conference presentations.
