A Ph.D. fellowship on functional programming language technology for high-performance deep probabilistic programming is available at the Department of Computer Science, University of Copenhagen. Application deadline: January 15th, 2020. Two Ph.D. fellowships are available on *deep probabilistic programming* (DPP) at the University of Copenhagen. The aims of one of these is to advance *functional high-performance computing* for DPP. This includes, but is not limited to, contributing to novel functional language and compiler technology for differential programming/automatic differentiation; domain-specific language design for programming with probability distributions and sampling from them; generating high-performance vectorized multicore or GPU code; and applications to deep learning, Bayesian inference and probabilistic programming. Application deadline:* January 15th, 2020*. For more information and for applying for the position, please see https://di.ku.dk/ominstituttet/ledige_stillinger/phd-fellow-dpp/.
