Dr Gareth J Bennett, BA, BAI, MSc, PhD, CEng, FTCD, Senior Member AIAA, Fulbright Scholar, is a Professor in the School of Engineering and is a Fellow of Trinity College Dublin, the University of Dublin, Ireland. His research interests lie in the domain of sound and vibration with current activities focused on aeroacoustics and metamaterials. He is an elected member of the Aeroacoustics Specialists Committee of the Council of European Aerospace Societies (CEAS-ASC) and is a member of the editorial board for the key journal in his field: International Journal of Aeroacoustics. Dr. Bennett has worked as a research fellow in the national nuclear facility of Portugal, a national fluid dynamics laboratory in Grenoble, France (LEGI) and in the School of Engineering in Stanford University where he was a funded Visiting Scholar. In 2016 he was awarded a Fulbright Scholarship to Notre Dame and NASA Glenn where he researched innovative low noise solutions to reduce aviation noise for a sustainable environment. In 2020 and 2023 he was the technical co-chair representing Europe of the AIAA/CEAS Aeroacoustics Conferences (AVIATION FORUM) in both Reno and San Diego, US. He has led research collaborations and published with over 25 international research labs, universities, and industries, including Harvard, Stanford, Bell Labs, Notre Dame, three institutions in China, Sherbrooke, KTH, Le Mans (LAUM), BME Hungary, Roma Tre, TU Delft, Airbus, Leonardo as well as the national aerospace institutes of France (ONERA), Germany (DLR), Italy (CIRA), the Netherlands (NLR) and the USA (NASA). Over 60% of his 120 peer reviewed journal and conference publications are co-authored with international collaborators and 20% are co-authored with international industry partners. To fund his research Dr. Bennett has won EUR 7M (EUR 3M-PI) in grants from e.g. the EU Commission, Enterprise Ireland, the Irish Research Council, the Naughton Foundation, the Fulbright Commission, industry and alumni. Dr Bennett has been the Principal Investigator on six EU framework collaborative research projects, of which he has been full project coordinator of three (14 partners), to conduct fundamental research and to develop solutions for quieter aircraft design. His current EU project: INVENTOR is funded within the H2020 Framework package and seeks to reduce airframe noise. In education, Dr. Bennett is active in Engineering Design Education research, supervising PhD activity and publishingly widely in this area, spending time in, and collaborating with Harvard and Stanford. He has designed and coordinates award winning user centred design modules which foster innovation and community engagement in engineering students and is a recipient of many education awards such as the prestigious Provost's Award for Teaching Excellence, the Dean's Award for Innovation in Teaching, a TCD Sustainability Leadership Award for teaching, a TCD Civic Engagement Officer Award and six national Lecturer Special Recognition Awards in Smarter Travel Education from the National Transport Authority (NTA). Between his MSc and PhD, Prof. Bennett worked in the industrial sector working, initially as a consultant in Vibration analysis, and subsequently as a Senior Mechanical Design Engineer: for an American Multinational- Thermoking, and for an Irish SME-Odenburg. He has supervised 9 PhDs to completion, mentored 6 post-doctoral research fellows and has supervised many, many master's students.

My research directly addresses the challenge of achieving a sustainable and healthy planet which is a key research goal in Trinity's strategic plan. My primary research area is aeroacoustics within the domain of aeronautics. My core research objective is to produce greener aircraft with lower emissions and lower environmental noise pollution. I am internationally recognised as the leading researcher in Ireland in Aeroacoustics as demonstrated by my leadership roles in the field internationally: 1. I am the only Irish representative on the Aeroacoustics Specialists Committee of the Council of European Aerospace Societies (CEAS-ASC), the EU technical committee which brings academic and industry interests together to shape the direction of aeroacoustics research in Europe. 2. I co-chaired the AIAA/CEAS Aeroacoustics annual conference twice in 2020 (Nevada) and 2023 (San Diego) flagship international conference for the CEAS and its American counterpart the AIAA. My technical co-chairs were leading American research scientists, e.g. Doug Nark from NASA. 3. I am on the editorial board for the key journal in my field: International Journal of Aeroacoustics 4. Over the last 15 years I have been PI on six large scale EU Framework funded collaborative projects with academic and industry partners: TEENI (FP7), WENEMOR (FP7), ALLEGRA (FP7), ARTIC (FP7), X-Noise EV (FP7) and INVENTOR (H2020). I was full project coordinator for three of these (WENEMOR, ALLEGRA, ARTIC), managing a total budget of €5.4M and 15 partners from universities, research institutes and industry. 5. I was the national focal point for aeroacoustics in the EU funded Coordination and Support action X-Noise EV. 6. I have led research collaborations and published with over 25 international research labs, universities, and industries, including Harvard, Stanford, Bell Labs, Notre Dame, three institutions in China, Sherbrooke, KTH, Le Mans (LAUM), BME Hungary, Roma Tre, TU Delft, Airbus, Leonardo as well as the national aerospace institutes of France (ONERA), Germany (DLR), Italy (CIRA), the Netherlands (NLR) and the USA (NASA). Over 60% of my 117 peer reviewed publications are co-authored with international collaborators and 20% are co-authored with international industry partners. My research spans the full breadth from fundamental discovery to applied research and has direct impact on reducing the negative effects of environmental aircraft noise on human populations. My collaborative research with industry in particular has achieved maximum test readiness levels (TRL) in EU funding. In these projects I led the co-development of low noise technologies for engine, landing gear and wings which have been validated and implemented by industry partners (including NASA, Airbus, Dassault, Safran, Rolls Royce, Leonardo) resulting in the reduction of environmental aircraft noise. To fund my research I have brought a total of €3 million to TCD in grants from for example the EU Commission, Enterprise Ireland, the Irish Research Council, the Naughton Foundation, the Fulbright Commission, industry and alumni. My publication record is extensive (h-index 23) with 55 journal articles, 66 peer-reviewed conference papers, 2 book chapters, one special issue in the key journal in the field (International Journal of Aeroacoustics) and a co-edited book of proceedings.
