Biography

Ronan received his BE and PhD from University College Dublin in 1993 and 1998 respectively. He worked with ICI/Zeneca Chemicals from 1993-1995 and Parthus Technologies from 1998-2001 as a mixed signal ASIC designer. In 2001 he joined Maynooth University as a lecturer, promoted to Senior Lecturer in 2010. In 2008 he was appointed Director for the Callan Institute for Applied ICT, and in 2012 was named Head of the Department of Electronic Engineering. In 2004, he became an SFI theme leader for radio frequency electronics research within the Centre for Telecommunications Value-Chain Driven Research (CTVR) and remains in that position. In 2008 he became a strand co-leader for sensors networks in an SFI Cluster on advanced Geotechnologies with a focus on wide area wireless sensor networks. Ronan has published over a hundred peer-reviewed papers. He holds three patents and licensed technology that has led to the spin-out three companies, Ronan’s personal research interests include wireless system design, electronics and radio systems
