Walter Henderson

Associate Director, Materials Characterization Facility
Principal Research Scientist

Walter Henderson manages a group of 8-10 research professionals that annually trains and helps ~700 researchers to perform 25000+ hours of work that enables ~$30M in research funding to Georgia Tech. 

He has significant experience in the growth, fabrication, and especially the characterization of microelectronic and nano-scale materials and devices. Henderson has been involved in this type of research since 1998 at all levels from vacuum system design and assembly to data analysis to paper and proposal writing/submission. 

Henderson has been an author on more than 30 publications in refereed publications such as the Journal of Applied Physics. His long-term goal is to move into education policy or public policy at the local or state level.

At Xindium Technologies (2000-2004), he developed a proprietary commercial-grade InP single-heterojunction bipolar transistor (SHBT) technology that led to the first demonstration of monolithically integrated 40Gb/s PIN+TIA differential-output optical receivers.

    Shen joined the Georgia Institute of Technology in 2005 as an Assistant Professor and was promoted a Full Professor in 2018. His research has yielded 8 awarded U.S. patents, 5 book chapters, 170+ publications in refereed journals and conferences, and many invited seminar talks to date. He is also an editor of a book entitled Nitride Semiconductor LEDs (2nd Ed., October 2017.)
