My main interest is in development, optimisation and modelling of organic waste management alternatives that allow implementation of circular economy approaches. My focus is also on evaluation of sustainability and environmental impacts of different organic waste treatment technologies.
During my Post-Doctoral work I evaluated, optimised and up-scaled fly larvae composting, which is a waste management system that allows recycling of not just plant nutrients, but also more valuable proteins and fats, which are typically lost in other types of organic waste management alternatives.
For my Doctoral degree I evaluated process optimization of food and garden waste composting, aiming towards reduction of greenhouse gas emissions.
My Master’s education in management of biological diversity focused on natural resource management, governance and stakeholder facilitation and social learning. I investigated conservation possibilities for an endangered plant species for my Master’s thesis. Originally a biologist with a focus on molecular biology and biochemistry, I evaluated plant proteins as markers for genetic selection of sunflower.
I lead the course "Sustainable technologies for low- and medium income countries, (TN0354)". I teach waste management, organic waste management alternatives and composting engineering in the following courses: Safe Nutrient Recycling (MX0131), Waste Management (TE0014) and Bioenergy - Technology and Systems (TN0284). Part of teaching includes practical work with ORWARE model, where students learn to implement systems thinking and a holistic approach when performing a comparison of different waste treatment alternatives. My teaching experience also includes a course on fly larvae composting for waste management industry professionals.
