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.

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" (2019), and "Conversational Argument Search (2020)".

I have served on the program committees of the Web Conference alternate track on Journalism, Misinformation, and Fact Checking (2018), CHI (2019), CIKM (2020), and CAIR (2020). I have also been reviewer for 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), TOIS (2020), and WIR-LWDA (2016).
