Data Science Group

Course Offerings in the Summer Semester 2025 

Here is some important information about the lecture and practicals offered by our group this upcoming summer semester 2025:

  • Vorlesung "Datenbanken (IDB)":  Bitte registrieren sie sich über heiCo für die Vorlesung und einen der drei Slots für die Übungen zur Vorlesung. Über die Mitteilungsfunktion in heiCo werden dann kurz vor der ersten Vorlesung weitere Informationen zur  Vorlesung mitgeteilt, u.a. der Zugang zu den Moodle Seiten zur Vorlesung.
    18.03.2025 Update:  es wird drei Übungsgruppen geben: (1) donnerstags 14-16 Uhr, SR C (Mathematikon), (2) freitags 9-11 Uhr Hörsaal Mathematikon, (3) freitags 11-13 SR C. Bitte registrieren Sie sich für eine Übungsgruppe in Müsli. 
    Note: Master students in Data and Computer Science are not eligible to take this class (besides the fact that the language of instruction is German). 
  • Seminar "Large Language Models and Reasoning": Please register via heiCo for this seminar (Bachelorseminar und Seminar, IS). In a first session on April 17, 2025, 2:15pm, we will provide more information about this seminar, the topics to be covered, and in particular how to apply for one of the 14 slots we have in this seminar. It is likely that this first session will be held online via Cisco WebEx. Information about the link to the online session will be posted via the forum for this seminar in heiCo.  Please also register in Müsli for the seminar.
  • Practicals "Data Science and NLP (beginners and advanced)": Information about both beginners and advanced practicals our group offers in the summer semester 2025 will be  presented in a single session online on April 16, 2025, at 2:15pm via Webex. Please enroll for the practicals via heiCo and Müsli. Through the forum in heiCo/Müsli we will let you know about the link to the online session a few days before the session. In this session we then present the topics for practicals and how to apply for a practical. Please note that we typically get many more applications than practicals we offer. In the summer semester, we expect to offer about 6-8 topics and practicals, respectively. 

People from the Data Science research group will typically in their offices but can also be contacted via email. In some cases, we also do video chats to talk about thesis issues, practicals etc., so don't send us lengthy emails. The secretary can be reached via phone Tu-Th 8:30am until 3:30pm and is in her office Th 9-2pm.


Welcome to the Data Science Research Group at Heidelberg University. Our research is centered around the management, processing, and analysis of complex data, ranging from scientific data and large-scale text data to  evolving network data. Research topics include

  • Data Science

  • Natural language processing (NLP)

  • Information retrieval and semantic search  
  • Machine learning  and deep learning

  • Complex network analysis

  • Legal Tech

Details about current and past research projects can be found here. Many of the research projects are interdisciplinary, covering application areas such as health sciences, law, politics, economy, physics, and biology.


The group offers several classes, seminars, and practicals at the introductory and advanced level. Besides an introductory course to Database Systems and a course on Data Science for Text Analytics at the bachelor level, at the graduate level we offer courses on Complex Network Analysis and Natural Language Processing with Transformers. A complete list of current and past courses and seminars can be found here.


Students interested in joining the group for a bachelor or master thesis or some interesting research project (introductory or advanced practical) can find some more information here.


Important note for international students interested in an internship: The group does not take any more international students for an internship for the academic years 2025 and 2026. Emails asking for an internship for that time period are very likely to remain unanswered.
