About Me
I'm a postdoctoral research scientist in the Statistical Machine Learning and Bioinformatics group led by Prof. Samuel Kaski and I'm working for the Helsinki Institute of Information Technology and The Finnish Centre of Excellence in Computational Inference Research. My research interest include Big-data Analysis, Likelihood-free Inference, Bayes Model Selection, Bayesian Classification, Unpaired Data-Integration for Genomics and Statistical Applications in Geology, Bioinformatics and Engineering.
