Dr. rer. nat. Bijan Fallah

Senior Scientist

With a background in applied physics, mathematics and climate research I excelled challenging problems while developing cutting edge solutions to scientific questions. For the last 8 years I have been wrangling, querying, analyzing, visualizing and communicating a variety of complex climate data-set. I have a bachelor degree in Physics, a master in Meteorology and finished my PhD in 2015 at Freie Universität Berlin under supervision of Prof. Ulrich Cubasch.

Currently, I am working in Green Central Asia project and will create open access, high-resolution climate change projections data-set, developed specifically for the region.
