PhD, Postdoctoral Researcher
I'm a postdoctoral researcher in the Probabilistic Machine Learning group at the Department of Computer Science at Aalto University and at Helsinki Institute for Information Technology HIIT. I am also a member of the The Finnish Centre of Excellence in Computational Inference Research (COIN). I received my PhD in statistics in 2013 from the Department of Mathematics at Åbo Akademi University. Prior to joining my current group, I've been a member of the Bayesian Statistics and Fisheries and Environmental Management groups at the University of Helsinki. In the years 2007-2013, I also worked as a statistician at the National Institute for Health and Welfare (THL).
Much of my current work focuses on developing methods for scalable Bayesian inference, distributed probabilistic modeling and learning from multiple data sources. I have previously done work on predictive modeling, Bayesian clustering and applications of state-space models in population dynamics.
