Overview

Richard O'Connell is affiliated with the University of Paris-Saclay in France. Their research primarily spans the fields of Agricultural and Biological Sciences, with significant contributions to Biochemistry, Genetics, and Molecular Biology. Their work focuses extensively on the subfields of Plant Science, Molecular Biology, and Cell Biology, alongside Biotechnology and Epidemiology.

The scientist's research topics emphasize plant-microbe interactions and immunity, plant pathogens and fungal diseases, and plant pathogen resistance mechanisms. Additional areas include fungal infections and studies, plant disease resistance and genetics, plant biochemistry and biosynthesis, and microbial natural products and biosynthesis.

O'Connell has published frequently in several scientific venues, with notable contributions in bioRxiv (Cold Spring Harbor Laboratory), where they have numerous papers, as well as Molecular Plant-Microbe Interactions. Other publication venues include the Journal of Experimental Botany, Nature Microbiology, and the Journal of Extracellular Vesicles.

  • Inhibition of jasmonate-mediated plant defences by the fungal metabolite higginsianin B (2020), Journal of Experimental Botany
  • The development of extracellular vesicle markers for the fungal phytopathogen Colletotrichum higginsianum (2022), Journal of Extracellular Vesicles
  • Identification of Copper-Containing Oxidoreductases in the Secretomes of Three Colletotrichum Species with a Focus on Copper Radical Oxidases for the Biocatalytic Production of Fatty Aldehydes (2021), Applied and Environmental Microbiology
  • Tandem metalloenzymes gate plant cell entry by pathogenic fungi (2022), Science Advances
  • Characterizing extracellular vesicles of human fungal pathogens (2025), Nature Microbiology
