Personal profile
Research
My focus is urgent land-use climate and environmental transitions in food production and consumption, possibly connected to bioenergy solutions covering plant nutrition and productivity (quality), spatial and temporal crop use-efficiency (annual and perennial species; e.g. intercropping, agrofoestry), soil fertility and residue management strategies to improve nutrient conservation and soil carbon sequestration. The target is more selfregulating and selfsuffcient land use practices reducing external input needs. In recent research, the technical solutions are addressed using participatory methods with great emphasis on actor involvement working within multidisciplinary teams.
Teaching
I am associated with the Technological and Socio-economic Planning education program (TekSam)
Project supervision: I have supervised students throughout my career within a wide spectrum of topics such as climate change, mitigation and adaptation; greenhouse gas emissions, bioenergy technologies, recycling of bioenergy residuals, biochar, phosphorus cycling, nitrogen cycling, symbiotic nitrogen fixation, crop production for food and feed, cropping diversification, water, nutrient leaching, …
Lecturing: I have been lecturing within subjects like climate change adaptation and - mitigation, bioenergy and substitution of fossil energy , biogas, thermal bioenergy technologies, circular thinking, biological cycles, nutrient cycling, nitrogen dynamics, nitrogen fixing crops, phosphorus and plant availability, self-sufficient and self-regulating plant production systems, diversity , organic farming, waste water treatment and recycling of nutrients
I am involved in teaching and project supervision in the International Bachelor Study Program in Natural Science (NatBas) and the Humanistic Technological Bachelor Study Program (HumTek)
