Dr Solomon Gebrechorkos

Solomon Gebrechorkos is a Research Associate in Hydrological Modelling at the School of Geography and the Environment, University of Oxford. Presently, he serves as an Editor and Editorial Board Member of Theoretical and Applied Climatology (TAAC) and an Associate Editor for Frontiers in Climate.

Solomon is a hydro-climatologist with expertise in hydrology and climate variability and change including modelling analyses of hydro-climate extremes such as floods and drought. He completed his PhD at the United Nations University /Technical University of Dresden, Germany in 2018 on assessing and modelling hydro-climatic extremes and climate change impact assessment in East Africa. Prior to joining the University of Oxford, he worked as a research fellow at the University of Southampton.

His research endeavours have delved into the realms of hydro-climate extremes, climate change impacts, and hydrological processes from catchment to global scale using a combination of hydrological and climate models and multiple forcing datasets such as observations, satellite, and reanalysis. Solomon has been involved in multiple large-scale projects such as FutureDams, EvoFLOOD, BRECcIA, and REACH and he has developed several high-resolution global-scale hydrological (https://catalogue.ceda.ac.uk/uuid/ac43da11867243a1bb414e1637802dec) and historical and future climate (https://catalogue.ceda.ac.uk/uuid/c107618f1db34801bb88a1e927b82317) datasets.
