David M.J. Cowell gained his Ph.D. from the School of Electronic and Electrical Engineering at the University of Leeds in 2008 working with the Ultrasound Group. His doctoral research area was advanced coding excitation techniques and excitation circuit design for industrial instrumentation and medical ultrasound imaging systems. He subsequently worked as a Research Fellow within the Ultrasound Group providing extensive consultancy in instrumentation, embedded systems, FPGA, and high-speed digital hardware design. Since 2015 he has held the position of Teaching and Research Fellow, with a focus on embedded systems and ultrasound. His ongoing research interests are in the area of high frame rate ultrasound systems for both medical and industrial applications, advanced ultrasound excitation systems with low harmonic distortion for array imaging, and signal processing for process measurement. His work has led to the development of the Ultrasound Array Research Platform (UARP) which is used within academic research groups and is currently being trialled medically with the Medical Discoveries Catapult and industrially within Sellafield as a key measurement technology for use during ongoing live nuclear decommissioning activities. He led the design of a portable passive magnetic measurement system for the remote inspection of buried oil and gas pipelines then conducted a global program of field trials and commercial surveys. This technology is now deployed commercially by Speir Hunter. His research work has led to several granted patents and publications. He is a member of the Technical Program Committee of the IEEE International Ultrasonics Symposium and has delivered multiple technical short courses.
