My research is driven by a central question: how do tropical atmospheric processes, from large-scale circulation to organized convection, shape rainfall and climate variability? I work across a range of time scales, from synoptic weather systems and intraseasonal oscillations to interannual climate fluctuations, seeking physical explanations for the patterns we observe.

Much of my work focuses on Mexico, Mesoamerica, the Caribbean, and northern South America. I have investigated the influence of the El Niño–Southern Oscillation (ENSO), the Madden–Julian Oscillation (MJO), and other modes of variability on precipitation, tropical cyclones, and regional hydroclimate. These questions connect atmospheric dynamics with practical challenges, including heavy rainfall, drought, thunderstorms, and vulnerability to weather-related hazards.

My research also includes studies of tropical clouds, aerosols, and atmospheric processes, reflecting an interest in understanding how different components of the climate system interact. I combine observations, reanalysis datasets, numerical simulations, and quantitative diagnostics to examine the mechanisms behind tropical weather and climate.

I value collaborative, reproducible research and the development of scientific tools that can be used by the wider community. Through open-source software such as PyWKSpectra, I aim to make methods for exploring tropical atmospheric variability easier to apply and reproduce.
