研究领域

I am fascinated by the important role of microorganisms (bacteria and archaea) in different ecosystems. I want to understand how communities can establish in soils that have been perturbed either by human manipulation or by a natural disturbance. My research area focuses on total microbial community (16S rRNA gene in bacteria and archaea) and specifically in herbicide-degrading bacteria (atz genes), ammonia-oxidizing microorganisms (nitrifiers AOA and AOB, amoA genes), methane-oxidizing bacteria (methanotrophs, pmoA genes) and anaerobic methane-producers by archaea (methanogens, mcrA genes). I study their role in several agricultural soils (from Chile, Germany and China), flooded rice and upland soybean fields (from China) and volcanic soils (from Chile). My current project is to identify antimicrobial resistant bacteria in soil by using stable isotope probing (SIP). We aim to discover which bacteria constitute the soil resistome in different British soils. We also want to understand if horizontal gene transfer (HGT) occurs between potential pathogens within soil microbiomes. I use culture-dependent (isolation, characterization and identification of bacteria) and culture-independent techniques, 13CO2-SIP and high throughput Illumina sequence to assess community diversity and obtain a distinctive fingerprint of the microbial community.
