Introduction
I am a postdoc and Schmidt Science Fellow in the Ermon Lab at Stanford. In my current work, I focus on statistical and machine learning models improving the prediction of crop yields in Africa. Before joining Stanford, I completed my PhD at the Karlsruhe Institute of Technology where I analyzed how different types of atmospheric waves create dry and wet periods over Africa, while demonstrating their potential for statistical rainfall forecasting.

Presentation
Equatorial waves (EWs) are synoptic- to planetary-scale propagating disturbances at low latitudes with periods from a few days to several weeks. Here this term includes Kelvin waves, equatorial Rossby waves, mixed-Rossby gravity waves and inertio-gravity waves, which are well described by linear wave theory, but also other tropical disturbances suc...

Short-term global ensemble predictions of rainfall currently have no skill over northern tropical Africa when compared to simple climatology-based forecasts, even after sophisticated statistical postprocessing. Here we demonstrate that \add{1-day} statistical forecasts for the probability of precipitation \add{occurrence} based on a simple logistic...

Rainfall over Africa varies across timescales of a few days to several weeks due to several tropical and extratropical modes of variability. Excessive rains or prolonged drought regularly result in natural disasters and have thus a severe impact on the local economy, agriculture, spread of diseases, and entire ecosystems. The dynamical nature of th...

Full-text available
Low-latitude rainfall variability on the daily to intraseasonal timescale is often related to tropical waves, including convectively coupled equatorial waves, the Madden-Julian Oscillation (MJO), and tropical disturbances. Despite the importance of rainfall variability for vulnerable societies in tropical Africa, the relative influence of tropical...
Article
This study presents the first systematic comparison of the dynamics and thermodynamics associated with all major tropical wave types causing rainfall modulation over northern tropical Africa: Madden Julian Oscillation (MJO), Equatorial Rossby waves (ERs), tropical disturbances (TDs, including African Easterly Waves), Kelvin waves, mixed Rossby-grav...

Article
Accumulated precipitation forecasts are of high socioeconomic importance for agriculturally dominated societies in northern tropical Africa. In this study, we analyze the performance of nine operational global ensemble prediction systems (EPSs) relative to climatology-based forecasts for 1 to 5- day accumulated precipitation based on the monsoon se...

In June and July 2016 the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project organised a major international field campaign in southern West Africa (SWA) including measurements from three inland ground supersites, urban sites in Cotonou and Abidjan, radiosondes and three research aircraft. A significant range of differen...
