After graduate school, Dr. Browning joined the Center for Electromagnetics Research at Northeastern University in Boston in 1988. While there he worked on microwave devices, space plasmas, and gated vacuum field emission devices. He also taught in the Electrical and Computer Engineering department. In 1992 he joined Micron Technology in Boise, ID where he worked on the development of Field Emission Displays (FEDs). His work included test and characterization, device physics, packaging, failure analysis, reliability, device design, device manufacturing, and cost analysis. In 1999 he joined PixTech, Inc. where he continued his work on FEDs with emphasis on manufacturing development. In 2001 he became a consultant on FEDs and on other display technologies with work in display characterization and testing, device analysis, and cost analysis. He joined the ECE department at Boise State in 2006. His research interests include microwave vacuum electron devices, vacuum nano-transistors, and cold atmopsheric pressure plasma for use in biofilm remediation.

- Study of Microwave Vacuum Electron Devices (MVEDs) including Crossed-Field Amplifiers and Magnetrons. MVEDs are used in a wide variety of civilian, industrial, and military applications where high power density or high frequency are need or where high reliability is needed. Our research looks at using Gated Field Emission Arrays as the electron source for magnetrons and Crossed-Field Amplifiers in order to improve performance and operational capabilities. Our research is also looking at the reliability and performance of Vacuum Nano-Transistors for use is harsh environments. Such micro-fabricated devices can be used at very high temperatures and in high radiation environments. Research is both experimental and through simulation and is supported by the Air Force Office of Scientific Research
- Plasma Agriculture and Medicine: Atmospheric pressure ionized gases (plasma) have the potential for numerous uses in biofilm remediation to kill or remove biofilms from food processing surfaces. The plasma can also be used to kill biofilms in chronic wounds. Our research looks at a novel plasma source arrays for these applications through experiment. This research is supported by the U.S. Department of Agriculture, the National Institutes of Health, and NASA.
