Rafael Luque (PhD 2005, Universidad de Cordoba, Spain) has significant experience in biomass and waste valorization practices to materials, fuels, and chemicals as well as nanoscale chemistry, green chemistry and (photo)catalysis (600+ publications, h-index 92, >39,000 citations, 7 patents, 10 edited books). He is Editor-in-chief of Molecular Catalysis (Elsevier) and has been named 2018, 2019, 2020, 2021 and 2022 Highly Cited Researcher (Clarivate Analytics). Carol Lin received her BEng degree in Chemicals & Material Engineering from the University of Auckland, New Zealand and her Ph.D. from The University of Manchester, UK. Dr. Lin is currently Associate Professor at the School of Energy and Environment, City University of Hong Kong. She is internationally known for her work on bioconversion of agricultural, food and industrial residues for production of chemicals, materials and fuels through green and sustainable chemistry. Her current research interests include cultivation of anaerobic human gut microbial consortia in cellulose hydrogel-based immobilized bioreactors, waste and biomass valorisation. Dr. Lin leads a team of researchers with a current grant portfolio of over HK$18M and on-going collaborations with numerous companies. She has given numerous Keynote and Plenary speeches at major international conferences. In 2016 and 2018, her research team won the Gold Medal at the Geneva Invention Exhibition. In 2017, she received The President’s Awards, CityU. Karen Wilson is Professor of Catalysis in the School of Science at RMIT University and was previously Chair of Catalysis and Research Director of the European Bioenergy Research Institute at Aston University (2013-17), where she also held a Royal Society Industry Fellowship in collaboration with Johnson Matthey. She holds a BA and PhD from the University of Cambridge, and MSc in heterogeneous catalysis from the University of Liverpool and has held academic positions at the University of York and Cardiff University. Her research interests lie in the design of tunable porous materials for sustainable biofuels and chemicals production from renewable resources. She is currently Associate Editor of the academic journals Sustainable Energy & Fuels, and Energy & Environmental Materials. Prof James Clark is a founding director of the world-leading Green Chemistry Centre of Excellence at the University of York, UK.
