About me

I’m a research scientist at IBM Research. I’m also an adjunct senior lecturer and co-supervisor at UKP Lab-TU Darmstadt. My primary research interest lies in the area of natural language processing (NLP), with a particular focus on language understanding in the discourse level, computational argumentation, and scholarly document processing. For more details, see my publications.

I am a member of the standing review committee of TACL. I also serve as a standing reviewer of Computational Linguistics (CL) journal. I have co-organized the 8th Workshop on Argument Mining, the Second/Third/Fourth Workshop on Simple and Efficient Natural Language Processing (SustaiNLP 2021, SustailNLP2022, SustailNLP2023), the First Workshop on Argumentation Knowledge Graphs, and the First Quantitative Summarization – Key Point Analysis Shared Task.
