Academic interests

At a general level, my research interests are focused around developing and applying statistical and machine learning methods for real-world applications. Some key topics are:

• Statistical machine learning

• Probabilistic graphical models

• Network structure learning

• Computational causal inference

• Statistical genomics

Background

I completed my PhD in statistics in 2016 at Åbo Akademi University (Finland), in which I developed a new class of probabilistic graphical models, along with algorithms for learning the structure of the models from data. During 2016-2020, I worked as a postdoc at University of Helsinki (Finland), developing and applying data analysis tools, primarily for applications in bacterial statistical genomics. Since February 2020, I have been working at UiO as an Associate Professor in Statistics and Data Science.
