Prof. Marcello Locatelli obtained his master’s degree in Chemistry and his PhD from the University of Bologna, Department of Chemistry "G. Ciamician". Currently, he is Associate Professor in the Analytical Chemistry at the University "G. d'Annunzio” of Chieti-Pescara, Department of Pharmacy. His research activity is devoted to the development and validation of chromatographic methods for the qualitative and quantitative determination of biologically active molecules in complex matrices. He contributes to the study of all processes related to pre-analytical stages, even the application of conventional and hyphenated analytical methods for the accurate, sensitive and selective determination. Recently, he has focused particular attention on innovative (micro)extraction procedures like MEPS, FPSE, MIP, DLLME, and SULLE. In the development of the method predictive models and chemometric both for the optimization of extraction protocols and for final data processing are also tested. Particular attention is given to the new instrument configurations for the quantitative analysis in a complex matrix. He is principal investigator for the project “PesCARA siCURA” funded by the Presidency of the Council of Ministers, Department for anti-drug policies for 350,000 euros. He has published more than 186 manuscripts, 158 congress communications (oral and poster), 16 book chapters and 6 books, and has been guest editor for 20 Special Issues which have attested scientific activity (based on Scopus (7th of September 2021), h-index 39, 174 papers, 4032 citations). Moreover, he is a reviewer of more than 106 International peer reviewed Journals. He is a referee for the MIUR Institution for National Projects (SIR), and included in the register REPRISE (Register of Expert Peer Reviewers for Italian Scientific Evaluation) in the "Basic Research" section. He is Editor in Chief of the journal "Analytica" and he is Editorial Board member of several journals.

Dr. Emanuela Gionfriddo is an Assistant Professor of Chemistry at the Department of Chemistry and Biochemistry of The University of Toledo (OH, USA). Research work in Dr. Gionfriddo’s lab focuses on the development of advanced analytical separation tools for the analysis of complex biological and environmental matrices, with emphasis on alternative green sample preparation methodologies. She received her B.Sc. (2008) and M.Sc. (2010) in Chemistry and her Ph.D. in Analytical Chemistry (2013) at the University of Calabria (Italy). She joined Prof. Pawliszyn’s group at the University of Waterloo (Ontario, Canada) in 2014 as Post-Doctoral Fellow and manager of the Gas-Chromatography section of the Industrially Focused Analytical Research Laboratory (InFAReL), and within three years became a Research Associate. Dr. Gionfriddo has currently authored over 50 peer-reviewed contributions including a patent on PTFE-based SPME coatings. Dr. Gionfriddo is one of the founding members of the Dr. Nina McClelland Laboratory for Water Chemistry and Environmental Analysis at The University of Toledo and she is appointed to the Ohio Attorney General Yost’s Environmental Council of Advisors. She serves as the Secretary of the ACS Subdivision on Chromatography and Separations Chemistry. Dr. Gionfriddo is also an Editorial Board Member for the journals Green Analytical Chemistry and Advances in Sample Preparation, Elsevier. Her research program is currently funded by the National Oceanic and Atmospheric Administration and several industrial partnerships.

Erwin Rosenberg holds the position of an Associate Professor for Analytical Chemistry at the Vienna University of Technology from which he also received his Diploma (1991) and PhD degree (1993). Following his habilitation on the topic of “Development and Application of Hyphenated Chromatographic Techniques in Environmental Analysis” in 2000, he also held a professor position at the University of Mining and Metallurgy Leoben (Austria) from 2002 to 2006. He is head of the Group of Organic Trace Analysis and has for more than 25 years been actively developing and applying chromatographic and hyphenated methods for (environmental) trace organic analysis. His current fields of interest are the development of sampling and analytical strategies and materials for volatile organic (and notably odorous) compounds in the industrial and environmental context, the development and use of multidimensional chromatographic techniques for environmental and natural substance analysis, and also the analysis of organic materials (binding media, dyestuffs, organic pigments) in cultural heritage materials and works of art. He is the author or co-author of more than 100 publications in peer-reviewed journals and proceedings, thirteen book chapters and has held numerous lectures at conferences. He has been and currently is a leader of several national and European projects, and is also a founding member of the European Virtual Institute for Speciation Analysis (EVISA). He serves as a regular reviewer for many analytical journals and for various European funding agencies and is an Editorial Board member of—among others—the MDPI journals Molecules and Separations, and also Associate Editor of Frontiers in Environmental Chemistry and responsible for the Section on Enironmental Analytical Methods.
