Academic Profile

I am a postdoctoral associate at CMU LTI working with Prof. Eric Nyberg on solving problems in intelligent legal information management and intelligent natural language dialogue systems while also teaching at the institute.

My work is best described as (Legal) Knowledge Engineering or (Legal) Data Science. It draws from artificial intelligence & law, knowledge representation & reasoning, natural language processing, applied machine learning, information retrieval as well as computational models of argument.

I obtained a diploma in law from the University of Augsburg, Germany, as well as a Master of Laws (LLM) and a PhD in Intelligent Systems specializing in AI&Law under Prof. Kevin Ashley at the University of Pittsburgh.

Projects

  • The LUIMA project in automated extraction of semantic information from legal texts towards a retrieval of legal documents that seamlessly connects to a lawyer’s understanding of her/his problem. It involves close collaboration with the AI&Law group at the University of Pittsburgh’s LRDC and the LLT Lab at Hofstra University School of Law.
  • The DialogQA project in developing a cognitive agent system able to engage in a question answering dialogue with a user, thereby maintain the conversational and topical context, as well as proactively obtain new information during the dialogue.
  • The VJAP model of value-based formal models of legal argumentation and case outcome prediction, which is my dissertation topic.
  • I co-teach core courses in CMU LTI’s Master of Computational Data Science (MCDS) Program and mentor student project work.

Miscellaneous

I have been involved in the Jessup Moot Court Competition for a number of years and taught Public International Law Advocacy at the University of Pittsburgh School of Law. This influences my research and teaching. I emphasize the ability of students to communicate their work and ideas effectively and engage in a productive dialogue with their peers and potentially non-domain-expert collaborators.

I spend a large part of my time with research-focused programming. During my exposure to symbolic AI, I acquired a taste for functional programming and LISP. My daily development toolchain largely consists of Clojure (-script), Vim, Eclipse, Java, UIMA RUTA, Python and the fountain of libraries coming out of Github.
