About me

Currently, I am working as a postdoctoral researcher at the Institute of Computer Science in the Database Systems Research group of Prof. Dr. Michael Gertz. Since January 2016 I am involved in the research project SCIDATOS (Scientific Computing for Improved Detection and Therapy of Sepsis), together with the Center for Scientific Computing (IWR) Heidelberg and the University Medical Center Mannheim (UMM). The project is funded by the Klaus Tschira Foundation. More ...

I am member of the Equal Opportunities Committee (Gleichstellungskommission) of the Faculty of Mathematics and Computer Sciences.

I studied Computational Linguistics, Near Eastern Archaeology and Jewish Studies at the Ruprecht-Karls-University Heidelberg and received my Magister Artium in January 2006. In 2011 I was awarded the PhD degree by the University of Cambridge. My dissertation is entitled “Latent Semantic Sentence Clustering for Multi-Document Summarization” and is available as Technical Report from the Computer Lab, Cambridge.

My last name is correctly written with a "ß" (sharp s or eszett). In German it is used only after long vowels and diphthongs while ss is written after short vowels. The HTML entity for ß is   ß.  In TeX and LaTeX, \ss produces ß.

Research Projects

  • SCIDATOS (Klaus Tschira Stiftung): Scientific Computing for Improved Detection and Therapy of Sepsis, together with the Center for Scientific Computing (IWR) Heidelberg and the University Medical Center Mannheim (UMM). The goal of the project is the reliable diagnosis of sepsis and its timely therapy in critically ill patients.
  • EventAE Event based Exploration of Linked Open Data (DFG): EventAE (Event Analysis and Exploration) is a joint project of the Database System Research Group of the Heidelberg University and the Databases and Information Systems Group of the Technische Universität Ilmenau. It is funded by the DFG.
