Dr. Nicola Botta

Senior Scientist

I am a senior scientist at PIK and adjunct professor (2019-2025) in the FP division, at the CSE Department, Chalmers University of Technology, Sweden.

I apply type theory, generic programming and program verification to climate science. I have active collaborations with M. Crucifix (UCL, Louvain-la-Neuve, Belgium), P. Jansson, T.-M. Fülöp (Chalmers University of Technology, Gothenburg, Sweden) and C. Ionescu (THD, Deggendorf, Germany). I am responsible for Theme 4 (Data and Decisions) and for part of work package 6 of the EU Horizon 2020 TiPES project. I am a developer of IdrisLibs and of the verified framework for sequential decision problems IdrisLibs/SequentialDecisionProblems. I have worked on agent based models of exchange economies with A. Mandel (CES, Paris, France) and on numerical methods for partial differential equations with R. Klein (FU-Berlin, Berlin, Germany). I have obtained a PhD from the Department of Engineering of the ETH Zürich.
