Loucas Tsakalakos is the Manager of the Photonics Laboratory within the Electrical Technologies & Systems, Micro & Nano Structures Technologies Organization at the General Electric – Global Research Center in Niskayuna, New York, USA. He received his BS degree (1995) from Rutgers University, and his MS (1998) and PhD (2000) degrees in Materials Science and Engineering (with minors in Solid State Physics and Microelectromechanical Systems) from the University of California, Berkeley. His expertise is in the integration of heterogeneous thin film and nanostructured materials systems for micro- and nano- device applications; he also has extensive experience in the characterization of materials. Since joining GE Global Research in 2000, Dr. Tsakalakos has designed and implemented integrated electronic and sensor systems for defense applications, studied cathode materials for lighting applications, and is a founding team member of GE’s Nanotechnology Program. His major area of research within that program was the development of nanostructured materials and devices, primarily using nanowires/tubes, working with multi-disciplinary teams both within GE and in collaboration with external partners. Loucas subsequently led the Advanced/Next Generation PV efforts within GE Global Research’s Solar Energy Platform. Most recently he worked within GE Energy – Solar Technologies and led a CdTe PV Module Product Engineering team at GE Global Research. In his current role as manager of the Photonics Lab, Loucas leads a team of 12 Ph.D. and M.S. level scientists and engineers developing advanced photonics technologies for data communications, sensing, and novel photonics applications. Dr. Tsakalakos is a member of Tau Beta Pi (The National Engineering Honor Society), is author or co-author of over 30 journal, conference proceedings, and book chapter publications, and holds 14 U.S. patents. He has given over 50 invited presentations at international conferences, symposia, and other events.
