Visiting sCholars
Scholars, who currently have their own funding source, and interested in visiting our group are encouraged to contact Dr. Gionfriddo for further information regarding current research projects. 
 Applications from individuals with prior experience in analytical chemistry, environmental chemistry, food analysis, bioclinical analysis, metabolomics, chemometrics, separation science and sample preparation are particularly welcome.  

Giuseppe Gentile

Visiting Master Student - University of Calabria

Giuseppe comes from southern Italy, he completed his B. Sc. In Chemistry in (2017) at the University of Calabria UNICAL. He is currently completing his M. Sc. In Biomolecular Chemistry at the University of Calabria. During summer 2018 he carried out an internship at the University of York (UK) where he developed a solid phase extraction method using starch-derived mesoporous materials (Starbon ®) to detoxificate fermentable liquor obtained from hydrothermal conversion of lignocellulosic biomasses.
During his internship in the Gionfriddo’s Research Group, he will use SPME coupled with GC-MS to investigate the effectiveness of antimicrobial food packaging materials by monitoring bio-indicators of food dysregulation.
