Research Interests
  • -Study bacterial-host interactions to (a) understand and phylogenetically analyse the genes involved in disease resistance at the cellular level in both the bacterium and the plant, (b) investigate symbiotic bacteria in insects of agricultural and sanitary importance, and (c) examine the microbiome in sea bream and sea bass.
  • Investigate microorganisms in extreme environments to (a) understand and map microbial communities, (b) examine the interactions among different microbial communities, (c) analyse the influence of external factors on their growth, (d) identify pathogenic microorganisms, (e) characterise new bacterial species as well as ancient ones. The study of microbial communities employs advanced molecular biology techniques such as genomics, metagenomics, single-cell genomics, and DNA microarrays; and (f) develop technologies for the characterisation and identification of symbiotic microorganisms and the characterisation of metabolic pathways and genes involved in pesticide degradation.
  • Microbes in aquaculture. The main aim is to develop protocols for detecting pathogenic viruses and studying and characterising microbial communities in larval and juvenile fish within aquaculture. Develop biopesticides targeting main fish pathogens like Vibrio spp, Aeromonas spp., Photobacterium, and VNN.
