Biography

Orla Feely is Vice President for Research, Innovation and Impact and a Professor of Electronic Engineering at University College Dublin. She holds a BE degree from University College Dublin and MS and PhD degrees from the University of California, Berkeley. Her research interests lie in the area of nonlinear electronic circuits, including MEMS, energy harvesters, power converters and phase-locked loops.

Professor Feely is a Member of the Royal Irish Academy and of the Board of the Irish Higher Education Authority.  She is a Fellow of the IEEE (Institute of Electrical and Electronics Engineers), Engineers Ireland and the Irish Academy of Engineering.  She is Chair of the EU Advisory Group on Marie Sklodowska Curie Actions, and past Chair of the Irish Research Council and of the IEEE Technical Committee on Nonlinear Circuits and Systems. 
 
Professor Feely has received the Best Paper Awards of the International Journal of Circuit Theory and Applications and the European Conference on Circuit Theory and Design. She was awarded the Distinguished Graduate Award of the UCD Engineering Graduates Association and the ESB Award for Outstanding Contribution to Engineering, both in 2015.  Her PhD thesis won the D. J. Sakrison Memorial Prize for outstanding and innovative research, awarded annually by the Department of Electrical Engineering and Computer Sciences at U. C. Berkeley.  She also won the U. C. Berkeley Outstanding Graduate Instructor Award in EECS.
