Dr Darren F Kavanagh
PhD, BEng (Hons) Nat Dip Eng MIEEE MIEI
Lecturer & Researcher, Faculty of Engineering
- Research Interests
- Research Supervision
Broadly, his research interests encompass the applied engineering field of Signals and Systems.
He received the Ph.D. degree in advanced signal processing and pattern recognition for acoustic signals from Trinity College Dublin, Dublin, Ireland, in 2011. He is a Lecturer with the Institute of Technology Carlow, Carlow, Ireland. He was a Postdoctoral researcher with the University of Oxford, Oxford, U.K., investigating the area of degradation and failure analysis of electric machines with specific applications in electric vehicles. He has gained valuable academic experience at educational institutions such as the University of Oxford; Trinity College Dublin; and the Institute of Technology Tallaght, Dublin, Ireland. He has also benefited greatly from industrial experience at Alcatel Lucent-Bell Laboratories, Intel, and Xilinx. Dr. Kavanagh was awarded an EMBARK Scholarship in 2006-2010 by the Irish Research Council to pursue a Ph.D. degree in acoustic signal processing for applied industrial problems. He was the recipient of the prestigious Minister’s Silver Medal for Science from the Minister for Education (Ireland) in 2004.
Industrial applications of his research include:
- Audio/Acoustic Signal Processing (DSP, Embedded Systems, Mixed-Signal ICs, Microphone Arrays, MEMS)
- Renewable Energy Technologies (Electric Machines, Generators)
- Electrification of Transport (Traction Motors)
- Industrial Revolution 4.0 (IoT based Smart Plant Equipment)
