I am a senior lecturer in DIT, School of Computing teaching undergraduate and post graduate courses. Teaching duties include network engineering including CCNA.Prior to working with the School of Computing, I worked with Sun Microsystems (Oracle) in Dublin as part of the Solaris ON-PIT group. I have previously worked with Cisco Systems in San Jose as part of the WNBU group where I investigated client issues using equipment such as Azymuth Test Bed for problem analysis. My Ph.D. titled, "Improving Multicast Communications over Wireless Mesh Networks" was carried out in the Communications Network Research Institute. My research involved creating physical test-beds using experimental hardware and creating custom simulations to develop power control and routing protocols. I am also a qualified electrician with a background in building services engineering with previous work experience with McArdle MacSweeny Associates and Building.
