Dr. Nicola Botta

I apply type theory, generic programming and program verification to climate science. I have active collaborations with N. Brede and T. Richter (Potsdam University), P. Jansson and T.-M. Fülöp (Chalmers University of Technology, Gothenburg, Sweden).  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.
