Presentation
I have a bachelor degree in Biological Sciences, a M.Sc. and a PhD degree in Aquaculture (Organic Waste Management). I am very interested in the recovery of organic resources (e.g. plant nutrients and bioactive substances) from waste streams and in the reutilization of such resources in food and feed production. The focus of my work is using black soldier fly (Hermetia illucens, BSF) larvae as a bioconversion tool for bioconverting organic residual streams, with the aim to achieve true circularity within the food supply chain. I am currently focused on the production, stabilization and application of high-quality BSF-derived fertilizers (frass or entomocompost). Frass is a novel organic fertilizer/soil amendment with incredible potential for increasing resilience and sustainability in agricultural systems, and my research is directed to unraveling its benefits and overcoming its limitations.
Research
- Biowaste treatment using BSF larvae
- Production and improvement of waste-derived fertilizers
- Use of organic fertilizers in horticultural production
- Dynamics of microorganisms in organic production systems
- Investigation of the effects of biostimulants in plants
Teaching
- Teaching “microbiology of composting” in the course Växtskydd och mikrobiologi (SLU Alnarp)
- Teaching “biostimulants in waste and wastewater” in the course Safe Nutrient Recycling (SLU Uppsala)
Educational credentials
I have a Master’s and a Ph.D. degree in Aquaculture, with focus on biowaste management, from São Paulo State University (UNESP), located in Jaboticabal, state of São Paulo, Brazil
Cooperation
My main research line is related to the use of BSF larvae in the treatment of biowaste and the further application of the frass fertilizer in crop production. In these subjects I am cooperating with projects in Brazil (greenhouse food production using insect-based fertilizers) and Madagascar (field production of distinct crops), in addition to ongoing projects throughout Sweden.
