I am a postdoctoral researcher at Empirical Inference Department, Max Planck Institute for Intelligent Systems working with Bernhard Schölkopf. I work in the field of machine learning (intersection of computer science and statistics). More specifically, my research interests range from non-parametric statistical tests, approximate Bayesian inference, to kernel-based feature representation of data. I completed my PhD study at Gatsby Computational Neuroscience Unit, UCL where I worked with Arthur Gretton on various topics related to kernel-based non-parametric statistical tests. I received MEng from Tokyo Institute of Technology where I worked with Masashi Sugiyama on supervised feature selection using squared-loss mutual information. Before that I was a research assistant working with Thanaruk Theeramunkong on a Thai news relations discovery project. I received BSc in Computer Science from SIIT, Thammasat university, Thailand.
I am always open for a research discussion. If there is a chance that I could contribute to your projects, please get in touch to discuss.
