Biography

Dr Chris Bleakley is an Associate Professor in the UCD School of Computer Science. His research focuses on computational sensing. He is currently leading research projects on indoor real time location systems, ultrasonic gesture recognition, ultrasonic indoor communications and ultrasonic sensing arrays. 

Prior to joining UCD in November 2003, Dr Bleakley was Vice-President of Engineering with Massana Ltd., a research-lead fabless semiconductor company. Dr Bleakley managed a multi-disciplinary, multi-site team comprising up to 50 engineers to deliver Massana's Gigabit Ethernet over copper Physical Layer Integrated Circuit (IC) products. Massana was one of only a handful of companies worldwide whose products passed the University of New Hampshire's 1000BT, 100BTx and 10BT Ethernet compliance tests. Massana's technology now provides the platform for LSI Logic's Gigabit Ethernet product line. In other projects at Massana, Dr Bleakley worked on FILU-200 (a ADSL OFDM embedded soft-core coprocessor), W-CDMA and Hard Disk Drive Read Channel ICs.

Before joining Massana in 1997, Dr Bleakley was a researcher with Broadcom Eireann Research Ltd, a research organization jointly owned by Ericsson, Eircom and Trinity College Dublin. His work at Broadcom focused on telecommunications management systems and networking. Dr Bleakley has worked as an IT consultant and programmer with Accenture and Beecom Int. Ltd.

Dr Bleakley obtained his PhD in 1995 from the Department of Electronic Engineering, Dublin City University. His thesis was on Low Bit Rate Speech Coding via extraction of physiologically based speech parameters. Dr Bleakley holds a 1st class honours degree in Computer Science from Queen's University, Belfast.
 
Dr Bleakley is a Senior Member of the IEEE and a Member of the ACM.
