Eder J. Lenardão is a Full Professor in the Center of Chemical, Pharmaceutical and Food Sciences of the Federal University of Pelotas, Brazil. He received his BS from State University of Londrina (1991) and MS degree from Federal University of Santa Maria (UFSM) in 1994, under the supervision of Professor Claudio C. Silveira. In 1997, he earned a PhD degree in organic chemistry at University of São Paulo, under the supervision of Professor Miguel J. Dabdoub and in 2003 he worked with Professor Antonio L. Braga at UFSM as a postdoctoral fellow. Prof. Lenardão was a Visiting Professor at Perugia University (CAPES fellow) where he joined Prof. Claudio Santi's group for one year (2015-2016). His research interest lies in the area of organic and green chemistry, developing new green protocols to prepare bioactive organochalcogen compounds.

Prof. Dr. Claudio Santi FRSC was awarded his PhD in 1996 under the supervision of Prof. Marcello Tiecco and in 1998 he received a fellow of the Swiss National Foundation to spend a period as visiting Scientist in the "Institute für Organische Chemie" of Basel University. He has been invited as visiting professor in Jagiellonian University in Krakow (2007) School of Chemistry Cardiff University (2009) Jan Dlugosz University of Czestochowa (2013) and Universidade Federal de Pelotas (2014). In 2002 he became assistant professor and in 2005 aggregate professor at the Faculty of Pharmacy of the University of Perugia. Since October 2013 he is associated professor of Organic Chemistry at the Department of Pharmaceutical Sciences of the University of Perugia and in the 2013 he received the National Scientific Habilitation as Full Professor. Prof. Santi is a worldwide-recognized expert in organoselenium chemistry. He has pioneered the studies on the use of optically pure diselenides in asymmetric synthesis and it was the first to envision the possibility to use organoselenium reagents (with particular emphasis on catalysts) in Green Chemistry. Currently he is leading the international Network of research on Seleniun Sulfur and Redox Catalysis (SeSRedCat).

Prof. Dr. Luca Sancineto graduated in 2008 with a bachelor's degree in Pharmacy at the university of Perugia with a comprehensive final grade of summa cum laude. In 2012 he obtained his PhD degree in medicinal chemistry with a thesis focused on the design and synthesis of novel anti-HIV agents targeting the viral transcriptional machinery. In 2010 he was visiting researcher at the "International Centre for Genetic Engineering and Biotechnology (ICGEB)" of Trieste. From 2014 to 2017 he was a PostDoc in the group of Catalysis an Organic Green Chemistry of the Department of Pharmaceutical Sciences at the university of Perugia. In 2015 he guest-edited a special issue for Current Green Chemistry Journal focused on new green advances in organochalcogens chemistry. In 2017, he was granted with the an individual Marie Curie fellowship in the context of the Polonez 2 project from the Polish Academy of Sciences. Presently he is independent researcher at the Centre of Molecular and Macromolecular Studies, Polish Academy of Sciences in Lodz. His research interest lies in the development of new greener procedure for oxidation reactions and in the design and synthesis of selenium-containing compounds endowed with biological activities.
