PD Dr. David Elsweiler

01 | Research

I am a private lecturer at the Chair of Information Science at the University of
Regensburg. My research focuses on the understanding of information behavior with the goal of designing information systems that align with the way people think and behave in a natural way.

Food recommendation systems

Two notable publications include Trattner and Elsweiler (2017) and Elsweiler et al. (2017a) by analyzing large-scale data collections from the Internet and proposing algorithmic solutions to influence users' health in food choices.

Information Sharing

Our group studied the information-sharing behavior of German politicians on social media in the 2017 election year.

Credibility and web search

Our group has studied how user bias affects the credibility of search results.

02 | Dissertation

In 2007, I completed my PhD at the University of Strathclyde in Glasgow. My work investigated the role of memory in managing personal information by examining what people remember when searching for documents and what factors influence what is remembered. I developed new systems that illustrate how different memories can be supported. Since completing my PhD, I have worked in a variety of areas, including leisure information behavior and trust and credibility in search and health recommendation systems. The underlying theme of my work is a desire to understand how people behave with information and why, and how systems can be developed to help users achieve their goals.

I am a lecturer and postdoctoral researcher in the Department of Information Science. In my research, I use a variety of different techniques to learn how people behave with information, and use what I have learned to design tools that support them and work in ways that are consistent with their thinking and behavior.

I've written a few papers, including my dissertation on managing and retrieving personal information. I'm interested in how people search for fun because current systems don't really support that well. Also, information systems that help people lead healthier lifestyles have piqued my interest. You can read more about this topic in my publications.

Previously, I was an Alexander von Humboldt fellow and then a lecturer at the
University of Erlangen.
