Christian Ludwig received his master’s degree (1990) and PhD (1993) from the Chemistry Department at the University of Berne, Switzerland. Post Doctoral years were spent at the Department of Land, Air, and Water Resources (LAWR), UC Davis, CA (1994-1995) and at the Swiss Federal Institute for Environmental Science and Technology EAWAG (1995-1997). 1997 he joined Paul Scherrer Institute (PSI). Today, he is head of a research group at PSI and adjunct professor at the Swiss Federal Institute of Technology at Lausanne (EPFL) in the field of Solid Waste Treatment.

Andrea Testino received his master’s degree in Industrial Chemistry (2000) and PhD in Material Science (2004) from the University of Genoa (Italy). He did post-doctoral studies at EPFL (CH), University College London (UK), and University of Milan (Italy) working on ceramic nanoparticles synthesis and characterization. In 2007 he joined the company TDK-EPC in Austria as Senior Development Engineer working in the Ceramic Components Division on Innovative Themes. In 2011 he joined the Paul Scherrer Institut, establishing the Advanced Nanopowders Synthesis Laboratory. Since 2022 he is MER (Maîtres d'Enseignement et de Recherche) at EPFL.

Laura Torrent received her master's degree (2014) and PhD (2019) from Chemistry Department at University of Girona, Spain. Her research interests are focused on the development and application of analytical methodologies for the determination of elements and nanoparticles, in order to evaluate their impact on energy processes and the environment.

Ayush Agarwal was born and brought up in India. He received his Bachelor of Engineering (B.E.) in Chemical Engineering from Birla Institute of Technology and Science (BITS), Pilani University in 2015. He worked as a process engineer at UltraTech Cement Limited before moving to Sweden for his graduate studies. He received his Master of Science degree in Chemical Engineering for Energy and Environment from KTH Royal Institute of Technology in 2019. He worked on high pressure bubbling fluidized bed gasification for his Master's thesis. Currently he is a PhD student at École polytechnique fédérale de Lausanne (EPFL) enrolled in the Doctoral Program in Energy (EDEY). His current work focuses on developing methods for analyzing micropollutants, and characterizing nanoparticles in process effluents and environment samples.
