Research statement

Imagine the amazing good fortune of the generation that gets to see the end of the world. This is as marvelous as being there in the beginning. — Jean Baudrillard, Fragments

{Winter is coming.} Climate change has pushed the hydrological cycle of the earth out of statistical stationarity. We are frequently observing unprecedented floods and droughts. The environmental system's response to such hydrological extrema is difficult to predict from existing observation data.

Physically-based mechanistic models can predict the system's response to previously unobserved extrema. The results of such model runs give insight into the environmental system's inner working and help to develop management strategies. Historically, such models were computationally expensive. But advances in computer technology now enable us to run these models at increasingly larger scales. This may lead to a paradigm shift in hydrology.

My research interest is in computational methods for environmental and geophysical flow problems. Ideally, these methods should fully leverage available data and computing power resources. My main tools are numerical methods for solving differential equations and high-performance computing, which I'm applying to study the resilience of urban and environmental hydrosystems to climate change.

Research interests

Generally speaking, I'm interested in theoretical and computational {fluid mechanics}, {applied linear algebra}, and a subset of {earth science} that relates to water flow.
