Despite its importance, accessing information in storage systems or raw data is challenging or impossible for most people due to the sheer amount and heterogeneity of data as well as the overheads and complexities of existing systems. Data-driven and \acs{ai} based approaches make it possible to provide the necessary information access for many tasks at scale, but can often only be used by experts and are expensive to use.
In my research I, therefore, develop low-overhead approaches, allowing data scientists, domain experts and end users to access and manipulate information in a quick and easy way. These approaches should work without the need for large amounts of training data, manually annotating or extracting information, and extensive computation, but still adapt to special terminology of different domains, and the individual information needs of the users. Moreover, they should be usable without extensive training; we thus aim to create ready-to-use systems that provide intuitive or familiar ways for interaction, e.g., chatbot-like natural language input or graphical user interfaces.
Beyond that, I'm interested in Ethical Aspects of AI and Machine Learning, in particular Explainability, Transparency and Fairness. Additionally, I try to incorporate relevant aspects of Human Computer Interaction.
I'm the research manager of the DFKI Site Darmstadt and a postdoctoral researcher at the Systems Group. In December 2023 I defended my PhD thesis titled “Democratizing Information Access Through Low Overhead Systems” under the supervision of Carsten Binnig.
I started working for the Data Management Lab as a PhD student in January 2018 and was part of the research training group AIPHES from July 2018 to June 2021. From July 2021 to March 2023, I was affiliated with the National High Performance Computing Center for Computational Engineering Sciences (NHR4CES).
From March 2021 to February 2023, I led the BMBF funded project INTEXPLORE – Interactive Structured Text Exploration, which I have acquired as part of the Software Campus.
In 2019, I co-organized the Conference of Aspiring Students in Tech Rhein-Main.
I obtained a Bachelor of Science in Computer Science in 2014 and a Master of Science in Computer Science as well as a Master of Science in Internet- and Web-Based Systems in 2017 all from Technical University of Darmstadt.
Between 04/2014 and 09/2017 I worked as student assistant for the Fraunhofer Institute for Computer Graphics (IGD). Additionally, I was student assistant for several different courses at Technical University of Darmstadt between 10/2012 and 12/2017.
During my studies I was a member of the student council and part of different commissions and groups as well as responsible for organizing the welcome week for first year students for five times.
