Dr. Andrea Trotta
Senior Researcher – Institute of Biosciences and BioResources – National Research Council of Italy
Dr. Andrea Trotta is a Senior Researcher of the Institute of Biosciences and BioResources (IBBR) of the National Research Council of Italy (CNR) in Sesto Fiorentino. He obtained his PhD in 2010 in Alessandria (Italy) working on the adaptation to high salinity of the photosynthetic apparatus in different halophytes, using a combination of biochemical and proteomics approaches. He then moved to the lab of Acc.Prof. Eva-Mari Aro in the University of Turku (Finland) to work in the Academy of Finland project lead by Dr. Saijaliisa Kangasjärvi on the role of a regulatory subunit of the PP2A phosphatase in the cross-talk between light acclimation and plant immunity in the model plant Arabidopsis thaliana. In 2014 he joint Eva-Mari Aro’s group to characterize by proteomics techniques the molecular mechanisms beneath the adaptation to abiotic stress in evolutionally different land plants. Taking advantage of the long experience in Finland, he is currently working on the natural variation of the genes encoding chloroplast proteins in higher plants, including conifers, by means of genetics and proteomics techniques.
