Remembering ECE Department Head Dr. Robert Kolbas

Remembering ECE Department Head Dr. Robert Kolbas

By Charles Hall

Dr. Robert Kolbas, professor and former head of the Department of Electrical and Computer Engineering at NC State passed away on June 7, 2020.

Kolbas was a professor at NC State from 1985-2020 and was Department Head from 1995-2000 of ECE, and then served as interim head from 2008-2009. He retired at the end of the Spring semester of 2020, and is remembered by hundreds of students who took his ECE classes.

He took extremely complicated concepts and equations, broke them down into understandable chunks,” described former student Richard Hodson (B.S. EE/CPE 2005, M.S. EE 2012). “He taught those chunks in a fun and effective manner that made learning the near impossible within reach.”

On October 26, 2017, ECE officially opened the ECE MakerSpace in Engineering Building II, consisting of two facilities – the Robert M. Kolbas MakerSpace, and the William F. Troxler MakerSpace. The two spaces serve to provide all of the resources students need to realize electronics and fabrication projects, both for Senior Design and other coursework as well as extracurricular and personal experimentation and creation.

Kolbas’ contribution and enthusiasm toward creating a space for students to be able to create and invent the future was contagious, and provided opportunities for students from across Engineering to tinker, experiment, and start their own enterprises utilizing tools and spaces that had never been available to them before.


When I was a student in the early-70s, I was very frustrated, because I wanted to build things, but I didn’t have the tools, I didn’t have the space, I didn’t have the parts. When I heard that the department wanted to make MakerSpaces, that’s what led me to make this donation because I don’t want our students to be as frustrated as I was.

Robert Kolbas

Kolbas was born on November 13, 1953 in Syracuse, New York and completed his Ph.D. in Physics from the University of Illinois in 1979 where he worked under Professor Nick Holonyak, Jr. in the early development of semiconductor quantum well heterostructure lasers. From 1979-1985 he was employed by Honeywell Inc. as a Principal Research Scientist and a Senior Research Scientist where he responsible for the development of Integrated Optoelectronic Circuits and the growth of semiconductor thin films.

Kolbas’s research interests and contributions included: III-V semiconductor heterostructures and quantum wells, optoelectronic integrated circuits, quantum well lasers, strained layer lasers, vertical-cavity lasers, ultra-thin quantum wells, carrier collection in quantum wells, phonon-assisted stimulated emission and AlGaN-GaN heterostructures, and II-VI semiconductor materials and devices. He published more than 140 manuscripts in refereed journals. His present interests include MBE, MOCVD, tunable light-emitting devices, light emission from nanoparticles, rare earth doped semiconductors, and wide bandgap semiconductor materials. He was a member of the IEEE, American Physical Society, Sigma Xi and Tau Beta Pi.

Memorial offerings in Kolbas’ memory can be made to NC State Engineering Foundation ECE’s Kolbas MakerSpace.

I started my teaching career in the department by co-teaching [his] electronics lab course. I learned so much and it’s still one of the best hands-on undergraduate courses here.
