I am a Sr. Applied Scientist at Amazon Search in Berlin. I'm interested in efficiency in NLP and search, and in system evaluation. Currently, I serve as an area chair for the Efficient NLP track at EMNLP 2023, having also held this role in the previous years (EMNLP 2022 and 2021). Furthermore, I am co-organizing the Eval4NLP 2023 workshop on evaluation and comparison of NLP systems. I am a member of the ACL working group on Efficient NLP. In the past, I co-organized the SustaiNLP 2022 workshop on simple and efficient NLP. Before joining Amazon, I completed my PhD at UKP Lab, TU Darmstadt, where I was also a member of the senior staff. Between 2008 and 2017, I worked as a freelance software developer for direct clients and advertising firms such as SYZYGY, Ogilvy, and ETECTURE.
