Catherine is a full-time PhD student of the School of Science and the Environment at the University of Worcester.  Catherine’s main research interest is about the use of biological control strategies against important pest of crops plants. 

In her PhD project, she is developing a study of the use of some beneficial bacterial strains against the cereal plant killer fungus Fusarium graminearum.  Her project involves the use of genomic and transcriptomic techniques as well as antagonisms assays to demonstrate the effectiveness of the biological control strategy.

So far, she has proved the wellness of the effect of the immune response of plants in the presence of fungal plant pathogens when the bacterial strains are present.  Her aims in the project are to provide insides on the genetic mechanisms on the interaction of the fungus – bacteria and how this relates to the antagonism assays results.

Catherine is a member of the British Society of Plant pathology as well to The International Society of Molecular Plant-Microbe Interactions.

Her PhD supervisors are Prof. Mahmut Tör, Dr. Amy Cherry and Dr. Paul Nicholson.

Prior to commencing her PhD, Catherine worked as a Research Assistant at the University of Costa Rica (UCR) on a Research Group developing a project on biological control against an insect pest on coffee crops at the CIBCR (Cellular and Molecular Biology Research Institute), for a period of more than 6 years she assisted to develop several projects with the use of the Bacillus thuringiensis including bioassays, production scaling and formulation of it.  As well she worked in an academic laboratory for molecular diagnosis of plant diseases at the CIPROC (Crop Protection Research Institute).  Additionally, she developed a collaboration with other research groups in the area of bioprocess and scaling agricultural importance microorganism’s production at the Agronomic Research Centre (CIA).
