Research Statement
Dr. Rahimi’s research is principally focused on creating and improving the quality/trustworthiness of high-resolution physics-based climate change projections via dynamical downscaling. He is also interested in quantifying how traditional forms of climate uncertainties (e.g., model choice, emissions trajectory, and internal variability) compare to the uncertainties introduced by choices made in downscaling (e.g., bias correction), and how these new uncertainties may amplify future uncertainty and distort the climate change signal, particularly for extreme weather events.
