Nelson Tansu was born on October 1977, and he received his B.S. degree (Applied Mathematics, Electrical Engineering, and Physics; with Highest Distinction) and his Ph.D. degree (Electrical Engineering / Applied Physics) from the University of Wisconsin-Madison in May 1998 and May 2003, respectively. Dr. Tansu served as tenure-tracked Assistant Professor (July 2003 – April 2007) and Peter C. Rossin Chair Assistant Professor (April 2007- April 2009) in the Department of Electrical and Computer Engineering (ECE) and Center for Optical Technologies (COT) at Lehigh University. Dr. Tansu served as an Associate Professor (with tenure) in the ECE department and COT at Lehigh from May 2009 till April 2010, and he served as the Class of 1961 Chair Associate Professor (with tenure) from May 2010 till May 2013 and New Century Endowed Chair Professor in Engineering and Applied Science (with tenure) from June 2013 till May 2014. Since June 2014 till present, Dr. Tansu has been appointed as the Daniel E. '39 and Patricia M. Smith Endowed Chair Professor at Lehigh University, and he was also appointed as the Smith Family Endowed (Founding) Director of the Center for Photonics and Nanoelectronics (CPN) at Lehigh.

Dr. Tansu’s research works cover both the theoretical and experimental aspects of the physics of semiconductor optoelectronics materials and devices, the physics of low-dimensional semiconductor (nanostructure), and MOCVD and device fabrications of III- Nitride and III-V-Nitride semiconductor optoelectronics devices on GaAs, InP, and GaN substrates. Up to today, Dr. Tansu has published in more than 290+ refereed international journal (105) and conference (190+) publications, and he holds several US patents (total > 14). Previously, Dr. Tansu has also given numerous lectures, seminars, and keynote and invited talks (total > 80) in universities, research institutions, and conferences in USA, Canada, Europe, and Asia. Dr. Tansu is an IEEE Senior Member, and recently his group’s works have received the IEEE Best Paper Award on Nanophotonics 2008 and Best Crystal Growth Image Award 2009.

Dr. Tansu serves as the Primary Guest Editor of the IEEE Journal of Selected Topics in Quantum Electronics (2008-2009) and IEEE / OSA Journal of Display Technology (2012-2013), and he also serves as an Associate Editor for IEEE Photonics Journal (2009-present), Associate Editor for OSA Optical Materials Express (2010-present), Associate Editor for Semiconductor Photonics and Technology (2011-present), Assistant / Associate Editor for Nanoscale Research Letters (2007-present), Associate Editor for IEEE / OSA Journal of Display Technology (2013-present), Associate Editor for Journal of Photonics for Energy (2013-present), Editorial Board for Photonics (2012-present) [as Editor-in-Chief for Photonics; 2013-present], and Editorial Board Member for Nature’s Scientific Reports (2014-present).

Dr. Tansu has also served as the Technical Program Committee for several major technical conferences for IEEE, OSA, SPIE, and APS; the selected lists include: IEEE / OSA Conference on Lasers and Electro-Optics (2007, 2008, 2009, 2013, 2014), SPIE Photonics West (2009, 2010, 2011, 2012, 2013, 2014, 2015), APS March Annual Meeting (2007, 2009, 2010, 2011), ACP (2012, 2013, 2014), and others. He also serves as the Representative of IEEE Photonics Society in Advisory Committee for IEEE Nanotechnology Council (2013-2015). Dr. Tansu was also selected as Invited General Participant at the 2008 National Academy of Engineering (NAE)’s U.S. Frontiers of Engineering (FOE) Symposium, and he served as the Organizing Committee for the 2009 NAE’s U.S. Frontiers of Engineering Symposium. Recently, Dr. Tansu has also been invited to participate in the NAE's 2012 German-American Frontiers of Engineering Symposium (GAFOE), and NAE's 2014 Japan-American Frontiers of Engineering Symposium (JAFOE). Since 2014, Dr. Tansu has also been appointed as the SPIE Visiting Lecturer(2014-present) and OSA Traveling Lecturer (2014-present).
