He is a Distinguished Professor of Chemical and Environmental Engineering and Editor-in-Chief of “Waste and Biomass Valorization” (www.springer.com/engineering/ journal/12649), a peer-reviewed journal published by Springer Nature, and the founding Chair of the WasteEng Conference Series (www.wasteeng2020.org), an international bi-annual series established in 2005. He is Chair of WtERT-France (Waste to Energy Research and Technology Council) led by Columbia University (USA), and a member of the management team of the Global WtERT Council www.wtert.org). He is a Visiting Professor at a number of top universities in the USA, Europe, China, India and Malaysia. He is also a board member of leading peer-reviewed engineering journals and committees. He has extensive expertise in fields such as energy and added value materials from biomass and waste; recovery of phosphate and inorganic elements from waste and biomass, recycling, functionalisation phosphate-based composites / hybrid materials (sorbents, fertilizers, catalysts, energy carriers, sensors) for energy, agriculture and depollution (liquid, gas, solid phases); thermochemical processes (pyrolysis, gasification, reforming) for biochar, bioash and energy production; the behavior of pollutants such as heavy metals and aerosols (fine particles) and kinetics and transfer phenomena. He has published 145 articles in peer-reviewed journals, 4 world patents (2 scaled-up at industrial level), co-edited 2 books on waste and environmental management and engineering fields, and presented 33 invited plenary and keynote lectures at international conferences. He has chaired and co-chaired 10 conferences and 2 international summer schools. He has obtained about 5.6 M€ of research grants over the 20 last years. He is Chair and principal Investigator of 3 joint Laboratories with industry. He has received international and national awards such as the Grand Prix 2018 of the Academy of Sciences of France for his outstanding contributions in science and technology of energy transition. He was also made an Erudite Professor of the Mahatma Ghandi University (India) in 2018. He was appointed as a member of the scientific advisory board of the World Bank PASET program (Partnership for skills in Applied Sciences, Engineering and Technology) Scholarship in Innovation Fund in 2018. He was also made a Knight of the National Order of Merit (France) in 2017. He has frequently worked as an adviser and evaluator for EU projects under the FP7 and H2020 framework programs.
