Biographical Summary

My primary research interests focus on extreme value theory for spatio-temporal data and analysis of weather and climate change. I am working on spatial dependence structure between extreme events. I am also interested in statistical applications to understand phenomena of rare events such as flooding, hurricane, heatwaves, etc.

Research Interests

Spatio-temporal modeling of extremes, time series analysis, applications to weather and climate change, CMIP5 model evaluation.
