About

I'm a PhD candidate advised by Gerhard Weikum and Krishna P. Gummadi (MPI-SWS). I am broadly interested in anything related to online users and language, and especially driven by problems with societal motivations or implications. My current research focuses on privacy aspects of information systems, being somewhere at the intersection of user-centric privacy, information retrieval, web mining, and the analysis of online communities.

Prior to joining MPI as a PhD student, I worked as an assistant in MPI's Ontologies group headed by Fabian M. Suchanek, contributing to projects in the area of information extraction and knowledge bases. I got my MSc and BSc degrees from the University of Wrocław, Poland, with a thesis in the area of natural language processing. Outside of academia, my professional experience includes two years of part-time jobs as a back-end web developer.

I spent the Summer/Fall 2017 in the Privacy Infrastructure team at Google Zurich, working on large-scale access log mining to construct graphs that track the internal flows of sensitive data.

Name

It is common for Polish names to have diminutives. Asia is a diminutive form of Joanna, not a nickname, and not a continent name :-) If you're curious how to pronounce it, have a look here.
