Biography

I am a researcher in agricultural development economics and bio-physical modelling of farming systems. My core research interests focus on the economics of drought as well as the interlinkages between environmental sustainability and socio-economic outcomes of farming systems.

My current research analyses if selected crop rotations prove to be generally more drought-resilient than others and provide farmers with a higher and more stable farm income. I also investigate which decision thresholds are suitable for deciding when to engage in opportunistic intensification in wet periods and fallowing in dry periods.

My ongoing research in sub-Saharan Africa investigates how the effectiveness of agricultural intensification and of climate adaptation measures varies across spatial gradients. My research aims to inform agricultural extension policies at the sub-national level.

As core methodologies, I am utilising crop modelling, econometrics, mathematical programming, and data science.
