Eugenia Reynoso. PhD
Associate Researcher
Eugenia obtained her BSc in Laboratory Technician and Microbiology at the National University of Río Cuarto (UNRC) in 2004 and 2009, respectively. In 2009, she was awarded with a PhD fellowship from the National Council for Scientific and Technological Research of Argentina (CONICET) for five years in the photochemistry research group of UNRC. She carried out her doctoral training under the supervision of Prof. M. A. Biasutti and co-supervision of Prof. N. A. García. The focus of her dissertation was the mechanistic and kinetic evaluation of the sensitized photooxidation of several antibiotics, and the microbiological implications of these processes. She obtained her PhD in Chemical Sciences in 2013. Then, she was awarded with a Postdoctoral fellowship from CONICET in 2014 for two years at the Photodynamic Inactivation research group of UNRC, under the supervision of Prof E.N. Durantini. Actually, she is an Associate Researcher at the Institute for Agro-industrial and Health Development (IDAS-CONICET), professor at the UNRC and a member of the Environmental Photochemistry and Photobiology research group (FQyFBA). Her main research topics are: direct and sensitized photodegradation of emerging contaminants in aqueous media and in microheterogeneous systems, mechanism and kinetics of photoprocesses, effect of solar radiation on the structure and functionality of bioremediating enzymes, photoprotection of bioremediating enzymes.

Agustina Reynoso. PhD
Postdoctoral Fellow
Agustina obtained her BSc in Chemistry at the National University of Río Cuarto (UNRC) in 2016. In the same year, she was awarded with a PhD grant from the National Council for Scientific and Technological Research of Argentina (CONICET) to carry out her doctoral training at the Institute for Agro-industrial and Health Development (IDAS-CONICET). Her thesis dissertation was supervised by Prof. José E. Natera and co-supervised by Prof. Walter A. Massad. Her doctoral investigation was center around the photocatalytic degradation of emergent contaminants. In August 2022 she will obtain her PhD degree in Chemistry and, at the same year, she will start a postdoctoral fellowship granted by CONICET at the Environmental Photochemistry and Photobiology research group (FQyFBA). Her postdoctoral fellowship will be focus in the development of biocompatible solid surfaces for the photoprotection of bioremediated enzymes.
Agostina obtained her BSc in Chemistry at the National University of Río Cuarto (UNRC) in 2021. This same year, she was awarded with a PhD grant from the National Council for Scientific and Technological Research of Argentina (CONICET) to carry out his doctoral training at the Institute for Agro-industrial and Health Development (IDAS-CONICET). Her thesis dissertation is supervised by Prof. H.A. Montejano and co-supervised by Dr. Gabriela Bossio, a member of the PHOTOKIN research group at the Institute for Theorical and Applied Physical Chemistry at La Plata, Buenos Aires.

Facundo Parodi. BSc
Doctoral Scholar
Laura is currently studying the last year of the career of Chemical Analyst at the National University of Río Cuarto (UNRC). She has collaborated in research activities in the Environmental Photochemistry and Photobiology research group (FQyFBA) since 2021. She has recently obtained a research assistant grant from the Secretary of Science and Technology of the UNRC, to carry out undergraduate scientific research under the supervision of Prof. H.A. Montejano and M.A. Biasutti, in the study of the kinetic and mechanistic aspects of the photodegradation of broad-spectrum antibiotics, promoted by UV-Vis light in the presence of humic acids. It is also intended to analyze the effect of these degradation processes on the antimicrobial capacity of these drugs.
