    Research interests

    My research interests lie primarily in developing statistical methods to analyse high-dimensional data which routinely arise in econometrics, machine learning, neuroscience, and social science. I began my research career by developing Bayesian statistical methods for mixture distributions with application in queuing systems. My current research is focused on developing Bayesian statistical methods in constructing networks for multivariate statistical analysis to understanding the underlying mechanisms in complex systems. These methods have applications in a wide variety of disciplines, such as capturing causal relationships between brain activities for treatment of psychiatric disorders. My motivation to develop these methods is to encode the relationships between the components in high-dimensional scale.

    Short Bio

    I am currently Assistant Professor of Statistic at the University of Amsterdam, Operations Management section.

    During 2016-2017, I worked as a postdoctoral researcher as a statistician at the Department of Methodology and Statistics at the Tilburg University and Jheronimus Academy of Data Science (JADS).

    In 2015, I received my PhD in Probability and Statistics from the University of Groningen, thesis entitled "Bayesian Model Determination in Complex Systems", supervised by Prof. Ernst Wit.
