Climate and Weather Extremes

My research investigates the growing occurrence and severity of simultaneous extreme weather events, such as tropical cyclones, and their compounded effects on vulnerable regions. I explore how different hazards, like heavy rainfall and strong winds, interact and amplify each other's impacts on both the environment and human populations. This research also examines how these compounded extremes challenge resilience in areas with limited resources, and how they impact ecosystems, agriculture, and critical infrastructure.

Remote Sensing and Earth Observation

I utilize a variety of Earth observation datasets, including IMERG, MODIS, and others, to analyze atmospheric processes such as dust emissions and precipitation patterns. A major aspect of my work focuses on understanding how spatial resolution influences the representation of precipitation in climate and weather models. By developing frameworks to assess the spatial scaling of precipitation, I aim to improve climate simulations and enhance the accuracy of precipitation forecasts. This research contributes to refining environmental monitoring systems and optimizing predictive modeling for regional climate behavior.
