Areas of Work

01 | Research

I'm PD at the Institute of Information Science at the university Regensburg. My research concentrates on understandig informational behaviour and has the goal of developing information systems that are acting natural, just like humans think and behave.

Food recommendation systems:

Two outstanding releases from Trattner and Elsweiler (207) and Elsweiler at. al. (2017a) contain analysis of extensive data collections from the internet and recommendations on algorithmic solutions for users' health when choosing food items.

Information Sharing:

Our group did resarch on information exchange behaviour from various german politicans on social media in the year of election 2017.

Credibility and web search:

Our group researched how prejudices of users affect the credability of search engine results.

02 | Dissertation

In 2007 I recieved a doctor's degree at the University of Strathclyde in Glasgow. In my work I explored the role of memory in management of personal information by testing human abilities, what they remember when looking for documents and which factors influenced their memories. I developed new systems that show how different memories can be supported. Since my graduation I worked in different areas, e.g. leisure information behaviour or credibility and trust in search- and health system recommendations. The core thought of my work is the wish of understanding how humans interact with information and why, further how to develop systems that support the user in reaching their goals.

I am a lecturer and post-doctoral researcher (wissenschaftlicher Mitarbeiter) at the Chair for Information Science. In my research I use a variety of different techniques to learn about how people behave with information and use what I learn to design tools to assist them and work in a way that aligns with how they think and behave.

I have done some work, including a PhD, on managing and re-finding personal information. I am interested in how people search for fun because current systems don't really support this well. I have also recently become interested in information systems that help people lead more healthy lifestyles. You can read more about this work on my homepage and in my publications. You can also find information about the classes I teach at Regensburg.

I was previously an Alexander von Humboldt Research Fellow and then lecturer at the University of Erlangen.
