Dublin, Ireland
Member of Technical Staff


2006-2009 University of Limerick, Ireland

PhD in Heat Transfer and Fluid Mechanics

Title: On the Heat Transfer and Fluid Mechanics of a Normally-Impinging, Submerged and Confined Liquid Jet 

2002-2006 Trinity College Dublin, Ireland

BA. BAI. (Hons. 1st) Mechanical and Manufacturing Engineering

Nick received a degree in Mechanical Engineering from Trinity College Dublin, Ireland in 2006, and subsequently achieved his PhD from the University of Limerick, Ireland in 2009 in the area of submerged liquid jets for enhanced electronics cooling. He was awarded a post-doctoral research fellowship to continue his research in fluid mechanics and heat transfer at Trinity College Dublin as part of the CTVR research center. Nick joined Bell Labs (Alcatel-Lucent) in 2011 as a member of technical staff where he now leads multiple projects in the areas of reliable active air-cooling and novel micro pumping architectures. Nick collaborates extensively in the local eco-system and co-supervises 6 PhD students.  He currently has 1 granted patent, over 16 patents pending and over 10 peer reviewed publications. His work to date has been recognized by numerous awards and prizes throughout his career.
