Janine Cossy studied at the Université Champagne-Ardenne in Reims, where she completed her PhD in photochemistry under the supervision of Prof. Jean-Pierre Pète. After a two-year post-doctoral stay with Prof. Barry M. Trost, at the University of Wisconsin (USA), she returned to Reims where, in 1990, she became Director of Research at the CNRS. The same year, she was appointed Professor of Organic Chemistry at the ESPCI Paris. Janine Cossy's research focuses on the synthesis of natural products and biologically active molecules (mainly with anti-tumor and anti-inflammatory properties) and on the development of selective synthetic methods in a variety of fields (photochemistry, radical chemistry, rearrangements, organometallic couplings, enzymatic reactions, enzymatic reactions, etc.). Currently, her work is focused on green chemistry, where she is developing catalytic synthetic methods using enzymes and low-pollution reagents.

Her research work has resulted in over 570 publications and 18 patents. She was elected to the Académie des Sciences in 2017 and to the Académie nationale de pharmacie in 2022. She was President of the Organic Chemistry Division of the SFC (now SCF), a member of the Organic and Biomolecular Chemistry Division at IUPAC. She was associate editor of Organic Letters (ACS)-and, right now, she is associate editor of Tetrahedron and associate editor of the Comptes-Rendus Chimie of Académie des Sciences. She is the co-founder of two companies, CDP-Innovation and Acanthe Biotech.

Dr. Eng. Salah Jellali currently holds the position of senior researcher in Water & Environmental Engineering at the Centre for Environmental Studies and Research (CESAR) of Sultan Qaboos University. His primary research focus revolves around local management and governance of solid and liquid wastes within the framework of circular economy and sustainability. A key area of his expertise involves the conversion of organic biomass into biochars. He has coordinated and participated in various national and international projects centered on the reuse of biochars as efficient adsorbents for wastewater treatment and/or as biofertilizers in agriculture. Additionally, he has actively contributed as a member of organizing and scientific committees for numerous international conferences on water and the environment. He has authored over 120 peer-reviewed scientific papers and book chapters and supervised several PhD theses and Master's students. Dr. Jellali received the best researcher awards of SQU in 2023.

Dr. Mejdi Jeguirim is a Professor at the University of Haute-Alsace (France) in the field of energy, process engineering, and kinetics modeling. He has coauthored more than 200 refereed international journal papers in his research field and is a member of the editorial boards for the following international journals: Energy, Energies, Energy for Sustainable Development, Biofuels, and the International Journal of Green Energy.
He is involved as a scientific expert for more than 50 international scientific journals as well as for several national and international research programs. He has received the French National Research Excellence Award for researcher with high-level scientific activity for the 2009–2012, 2013–2016, 2017–2020, and 2021–2024 periods. Dr. Jeguirim has appeared in the World’s Top 2% Scientists ranking established by Stanford University since 2019.
