Principal Investigator
Dr. Emanuela Gionfriddo
Assistant Professor 

Dr. Gionfriddo received her B.Sc. (2008) and M.Sc. (2010) in Chemistry and her Ph.D. in Analytical Chemistry (2013) at University of Calabria (Italy). She joined Prof. Pawliszyn’s group at the University of Waterloo (ON, Canada) in 2014 as Post-Doctoral Fellow and manager of the Gas-Chromatography section of the Industrially Focused Analytical Research Laboratory (InFAReL), and in 2017 became a Research Associate.

Since January 2018 she joined the Department of Chemistry and Biochemistry at the University of Toledo (Ohio, U.S.A.) as an Assistant Professor of Analytical Chemistry.
