July 2018: I submitted my PhD thesis to WeST Institute at University of Koblenz-Landau, Germany
May 2018: I gave a talk at WebSci'18 in Amsterdam, Netherlands
April 2018: My book chapter on "Tag-based Navigation and Visualization" has been published as part of "Social Information Access: Systems and Technologies"
The research fields that I am interested in are network science and data science, but I try to focus my research around one word - navigation. Navigation is the process of following links in order to find a specific information piece. The main advantage of navigation over search lies in the human's congnitive abilities and in the fact that poeple are better in recognizing things than describing them. That is why, picking the right link is much easier than formulating a search query. With my research, I want to study the decisive points for building software systems that support efficient navigation: the social processes responsible for shaping an information space, designing user interfaces able to expose the structure of an information space and modeling user navigation.
