Prof. James Hwang leads one of the most active research groups in the department.
Hwang graduated with a Ph.D. degree in Materials Science and Engineering from Cornell University in 1978. After years of industrial experience at IBM, Bell Labs, GE, and GAIN, he joined Lehigh in 1988. He co-founded GAIN and QED; the latter became the public company IQE and remains the world's largest compound semiconductor epitaxial material supplier.
Hwang was a visiting professor at Cornell University, Marche Polytechnic University in Italy, Nanyang Technological University, Singapore, National Chiao Tung University in Taiwan, and Shanghai Jiao Tong University, East China Normal University, and University of Science and Technology in China.
From 2011 to 2013, he was a Program Officer for GHz-THz Electronics at the U.S. Air Force Office of Scientific Research. He has published more than 350 refereed technical papers with the citation index h > 40, according to Google Scholar.
Hwang has been granted eight U.S. patents. He is a Life Fellow of the Institute of Electrical and Electronic Engineers.
