Interessi di ricerca
  • The diversity and structure of microorganisms associated with wild plants growing in extreme environments such as cold habitats
  • Functions of these plant-associated microorganisms including their role in alleviating various biotic (diseases) and abiotic (chilling and freezing) stresses on plants
  • Developing innovative and practical management strategies against different plant stresses; and eventually developing them into various plant protection products (e.g. biopesticides and biostimulants).  
Attività di ricerca

My research career as a plant pathologist started as a Master’s student where I focused on evaluating the suppressive effect of Allium intercropping on tomato bacterial wilt, and on the bacterial community structure of Alliums and tomato. Afterward, as a Ph.D. student, I utilized the bacterial community data to develop novel biocontrol agents against tomato bacterial wilt, which was the main research area of my dissertation. In this study, I succeeded in developing a practical biocontrol strategy against tomato bacterial wilt.

As a postdoctoral researcher (I), I have been investigating the competition for nutrients as one of the mechanisms employed by the newly discovered microbial biocontrol agents (MBCAs; Mitsuaria and non-pathogenic Ralstonia) against the tomato bacterial wilt pathogen (Ralstonia pseudosolanacearum), genome analysis of these MBCAs and the pathogen, transcriptome analysis of tomato plant following MBCAs treatment and pathogen challenge inoculation.

As a postdoctoral researcher (II), I have been studying the various interactions between dark septate fungal root endophytes - host plants (ornamentals and fruit crops) - pathogens (oomycete and fungi). In particular, I succeeded in developing a practical biocontrol strategy using a new DSE against Pythium root rot on eustoma plant for hydroponic culture system.
