Ph.D. student Ioana Brezeștean received her Bachelor Degree of Science in Medical Physics (2013) and the Master Degree in Biomedical Physics (2015) from Babeş-Bolyai University (Cluj-Napoca, Romania). At the moment, she is a Ph.D. student at Babes-Bolyai University.
During the Ph.D., she did an internship at the Faculty of Aquaculture, Dubrovnik, Croatia, where she gained experience on rapid SERS detection of cyanobacteria and toxins from the natural environment by using a Portable Raman system.
Since December 2018, she is working at the National Institute for Research and Development of Isotopic and Molecular Technologies (INCDTIM), now as a Scientific Researcher (CS), where she is involved in several research projects for collecting Raman and SERS spectra as a key expert.

PhD student Ana Maria Raluca Gherman has been active in the field of molecular modelling for six years, ever since she began her master degree studies at the Faculty of Physics, at Babeș-Bolyai University of Cluj-Napoca, under the guidance of Prof. Vasile Chiș. She is an expert in describing quantum chemistry-aided structural and electronic properties of biomolecules, mainly active compounds of drugs by using Density Functional Theory (DFT). She focuses mainly on vibrational spectra resulted from frequency calculations.
She began using multivariate analyses such as Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), and PCA-LDA on vibrational spectral (i.e. SERS) databases registered on pathogenic microorganisms (bacteria, fungi, yeasts) as a member of two research projects since 2016. Her activities on these projects have materialized into a statistical model for identification, discrimination and classification of pathogens.
She is also able to manipulate a DeltaNU Advantage and Renishaw Raman spectrometer, and a Jasco UV-Vis spectrometer, having experience in recording Raman (powder and liquid) and SERS spectra of drugs.
Her research focuses mainly on the interaction between bactericidal compounds and their specific target by using computational tools. As an alternative to DFT calculations, she is gaining experience into the field of molecular docking studies, exploring ligands-receptor systems, with ligands belonging to the pharma field, in terms of geometry specificity and binding energy.
