Dr Matias Quiroz
Associate Investigator
I received my Ph.D. degree from the Department of Statistics at Stockholm University 2015, under the supervision of Professor Mattias Villani. I also hold a M.Sc. degree in Engineering Mathematics from Lund University (2009). I joined ACEMS in 2017, where I worked under the supervision of CI Professor Robert Kohn until 2019. I am currently a Lecturer in Statistics at the University of Technology Sydney (UTS).
My research interests lie in the area of Bayesian Statistics. In particular, I am interested in computationally challenging problems, especially in Markov chain Monte Carlo simulation algorithms and variational inference.
