Personal profile


Keith Brown received his BSc degree in Electronic and Electrical Engineering from the University of Edinburgh in 1984. He completed his PhD “Knowledge based fault diagnosis of 16 QAM microwave radio relay equipment” at the University of Edinburgh in 1988. He joined Heriot-Watt University’s Department of Electrical and Electronic Engineering in 1987. He is currently a senior lecturer in the Institute of Sensors, Signals and Systems, which is part of the School of Engineering and Physical Sciences. He is also Head of the Discipline of Electrical, Electronic and Computer Engineering.

Research interests

Keith Brown has research interests in underwater acoustics, in particular bio-inspired sonar systems. This work has application in the analysis of a variety of underwater assets (to aid with their condition based monitoring) and identification of underwater objects. He is looking at new approaches to finding out the content of underwater objects using wide-bandwidth acoustic signals.  He also has interests in the intelligent diagnostics and control of complex systems. This work has been applied to autonomous underwater vehicles that work in hostile remote environments with limited communications to operators.
