I studied computer science at the Bauhaus-Universität Weimar. I then joined the Webis group as a PhD student in 2014 after successfully defending my master thesis.

My main areas of interest are conversational search and web archives. I'm the main developer of publicly available tools for web archiving, personal web archiving, web page content extraction, historical IP geolocation, and collecting human annotations. I'm also the main developer for the args.me argument search engine (since 2018). I have been the main responsible person for the SemEval/PAN 2019 Task for Hyperpartisan News Detection and am currently co-organizing the SCAI-QReCC-21 conversational question answering task.

I have been repeatedly teaching assistant for the lectures Search Algorithms (2014), Databases (2015, 2016, 2017, 2018), and Web Technology (foundations: 2016, 2017, 2018, 2019). I mentored several student theses and supervised student projects on "Big Data and Cryptography" (2014), "Linking Discussions", "Advanced Web Search Methods" (2015), "Search by Voice", "Interactive Argument Search" (2017), "Large-scale Web Archiving and Analysis", "Voice-based Argument Search" (2018), "Conversational News", "Arguments from Email Data" (2019), "Conversational Argument Search", "Conversational Argument Search II" (2020) and "Knowledge and Argument Graphs in Voice Search" (2021).

I have served on the program committees or as reviewer for the Web Conference alternate track on Journalism, Misinformation, and Fact Checking (2018), CAIR (2020), CHI (2019), CIKM (2020, 2021), CLEF (2014, 2016), DBSpektrum (2015), EACL (2017), ECIR (2018, 2020), EMNLP (2016), HCOMP (2018), HT (2020), KDML-LWDA (2016), NAACL (2016), PAN (2019), SEMEVAL (2019), SIGIR (2016, 2021), TOIS (2020), and WIR-LWDA (2016).

I'm a junior member of the SIGIR Artifact Evaluation Committee (2021).

I'm a member of the parent's council of the Kindergarten associated with Bauhaus-Universität Weimar (since 2019).
