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. I defended my dissertation in 2022.

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 co-organizing the SemEval/PAN 2019 Task for Hyperpartisan News Detection (2019), the SemEval/Touché Task on Human Value Detection (2023, 2024), the SCAI Eval task on evaluating search-oriented conversations (2024), the SCAI-QReCC conversational question answering task (2021), and the Touché Task on Image Retrieval for Arguments (2022, 2023, 2024). I have been involved in organizing the SCAI (2024) and Touché (2022, 2023, 2024) workshops.

I have been repeatedly teaching assistant for the lectures Search Algorithms (2014), Databases (2015, 2016, 2017, 2018), Introduction to Machine Learning (2022, 2023), 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), "Knowledge and Argument Graphs in Voice Search", "In Dialog with the Virtual Museum" (2021), "In Dialog with the Virtual Museum II", "Automatic Image Captioning", "So Tell Me Why - Investigating Personalized Argument Search" (2022), "Mining Arguments from Podcasts", and "Multimodal Sequence Representations for Feed Data" (2023).

I have served on the program committees or as reviewer for the Web Conference alternate track on Journalism, Misinformation, and Fact Checking (2018), ArgMining (2021, 2023), CAIR (2020), CHI (2019, 2023), CHIIR (2024), CIKM (2020, 2021, 2022), CLEF (2014, 2016), CLEF Labs (2022, 2023, 2024), COLING-LREC (2024), CUI (2022), DBSpektrum (2015), EACL (2017), ECIR (2018, 2020, 2023, 2024), EMNLP (2016), HCOMP (2018), HT (2020), IJCAI (2023), KDML-LWDA (2016), NAACL (2016), PAN (2019), SemEval (2019), SIGIR (2016, 2021, 2023), TOIS (2020, 2022, 2023), Touché (2022, 2023), TPDL (2022, 2023), and WIR-LWDA (2016).

I am a paper chair for CUI 2024.

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

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