My research since 2013 has centred on multi-scale convective heat transfer for thermal management of electronics systems. This is underpinned by my expertise in experimental fluid dynamics, developed during my Ph.D. work in KU Leuven and my postdoc career in TCD and Purdue University. The focus on electronics cooling is inspired by (i) the rapidly growing energy use of electronics systems and data centres, (ii) the need to better integrate these with our energy system, e.g., through waste heat recuperation, and (iii) the interdisciplinary R&D effort needed to accomplish this - requiring collaboration between thermal fluid science and electronic engineers, as well as more effective knowledge transfer between industry and academia. Since 2013, I have supervised an active team of an average of 5 PhD students and 3 postdoctoral researchers. A lot of early work went into the fundamentals of heat transfer enhancement with flow unsteadiness (pulsating flow, synthetic jets) and its use in confined geometries, like those in electronics systems. Because of the analogies with aerodynamic flow control, we applied similar techniques to active flow control with applications in renewable power generation. My research has a strong experimental focus requiring high spatial and temporal resolution measurements of flow and thermal quantities using advanced techniques (e.g., particle image velocimetry (PIV), infrared thermography, constant temperature anemometry). Along the way, we developed new and improved measurement techniques (e.g., high dynamic range PIV) and gradually expanded our expertise to include advanced computational modelling and numerical optimisation. My team is now internationally recognised for novel research on data centre thermal management and convective flow control, and is firmly embedded in multiple SFI research collaborations (CONNECT, ESIPP, SSPC, MaREI) and closely engaged with academic and industry leaders in the field, through my links with CTRC in Purdue and editorial roles in top journals in the field of electronics cooling.
