Biography

I am Dr. Tanvir Ahmed, an Associate Professor in the Department of Physics at Shahjalal University of Science and Technology (SUST) in Sylhet, Bangladesh. Currently on leave from SUST, now, I am working as a Research Scientist at the Institute of Meteorology and Climate Research (IMK-TRO) at the Karlsruhe Institute of Technology (KIT) in Germany. My research focus on understanding extreme weather events in present and near-future climate scenarios, utilizing high-resolution numerical models such as WRF and ICON.
In addition, I have been appointed as a visiting research associate at the International Centre for Theoretical Physics (ICTP) in Trieste, Italy, from 2023 to 2028. During this tenure, I am collaborating with the Earth System Physics (ESP) group, with a particular focus on Regional Climate Modeling (RCM). Previously, I served as a PGD Fellow in the ESP group at ICTP. I earned my Ph.D. from Seoul National University in 2021 and hold both a B.Sc. (Honors) and an M.S. in Physics from Shahjalal University of Science and Technology.
