Isabel Trillas Gay is Professor from Department of Plant Physiology at University of Barcelona. Her topic of interest is Biological control of plant diseases. Plant microbe interactions. Composts to suppress Plant diseases. Organic waste recycling by composting. Plant tissue culture.

 The research has been focussed on the study of plant disease control with the use of composts (organic wastes) and microorganism biological control agents. We are attempting to improve our understanding of how the chemical and physical environment of composts selects specific microorganisms, the microbial activities that take place, and how theses communities influence plant disease control (soil-borne and aerial pathogens). Presently, our research is focused on associations of plants and biological control agents. We are working towards a fundamental understanding of plant responses to microbe / composts associations so that the practical utilisation of microbes / composts for biological control /integrate management of plant diseases may become more efficient and safe.  Dra. Mª Isabel Trillas is inventor of the patents: ES2188385 B1, EP 1400586 B1, US 7,553,657 B2, and involved in the development of the biological control agent Trichoderma asperellum, strain T34 and entrepreneur, partner and Scientific Adviser of Biocontrol Technologies, S.L..
