Research Interests

My research focuses on the management and interactions of agriculture and natural resources under increasing societal demands and climate change including extreme events. I am employed as a Scientific Officer at the European Commission - Joint Research Centre (DG JRC). 

Our activities centre on the operational forecasting of national crop yields with the MARS Crop Yield Forecasting System with a special focus on the European Union and neighbourhood countries. These forecasts are published monthly in the MARS Bulletin. For an overview of our activities check out these 5 short videos.

Besides investigating the quality of our forecasts - with the aim to improve them - by e.g. better linking crop yield and weather variability, I am also involved in large-scale assessments of crop growth, food production, agricultural water and nutrient use, soil management (nutrients and carbon), bio-energy, and their impacts on the environment. 
DG JRC Ispra
I have a particular interest in better understanding the interaction of farm management, climate change, and crop production across different agricultural systems.

I am also active in evaluating crowd-sourcing applications including the mining of web search data for agro-environmental applications, as well as citizen science applications for agricultural monitoring, particularly within the H2020 LandSense project.
