My name is Martin Trapp, I’m a PhD candidate in machine learning. I have a particular interested in deep tractable probabilistic models, probabilistic programming and on Bayesian nonparametrics for probabilistic modelling.

My thesis is supervised by Prof. Franz Pernkopf from the Graz University of Technology in cooperation with Dr. Robert Peharz from the University of Cambridge. I’m also affiliated to the OFAI led by Prof. Robert Trappl.

In my spare time, I’m working on the universal probabilistic programming language Turing.jl. Our goal is to provide efficient, robust and intuitive probabilistic programming for everyone.
