Dánnell Quesada [ ˈdanel keˈsaða ] works as researcher in the group Data-centric modeling of cross-sectoral climate impacts. His research focuses on bias-correction and downscaling techniques of climate projections, particularly for the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP). His research interests include:

  • Biodiversity
  • Extreme weather
  • Compound events
  • Machine learning

I studied Civil Engineering, with an emphasis in hydrology and hydraulic engineering, at the Universidad de Costa Rica, where I obtained my Licentiate degree in 2014. I worked for 3 years in the renewable energy consultancy sector, where I developed a keen interest in the implications of climate change, particularly on energy production and biodiversity. In 2016, I received a DAAD scholarship to pursue a Master's degree in Hydro Science and Engineering at the TU Dresden. My master's thesis dealt with downscaling of climate projections for Costa Rica through machine learning.

In 2020, I was awarded a joint schorlarship from the European Social Fund (ESF) and the Federal German state of Saxony for my doctoral project, to develop a deep learning algorithm that downscaled a multivariate dataset to a daily 1 km ensemble for Saxony. I then used this dataset to predict the future distributions of certain endangered species. I joined PIK in 2023 as part of the research group Data-centric modeling of cross-sectoral climate impacts.
