My core research topic is about topics - probabilistic topic models, to be precise!

Topic models typically detect topics by co-occurrences of words on text documents. I include contexts - such as geographical coordinates - to detect co-occurrences of words in documents and the context space.
Besides topic modelling, I'm generally interested in probabilistic modelling for aiding research in the social sciences.

In my free time, I'm politically active (e.g. fighting for data privacy), am member of a humanistic club and go biking
