Short CV
I am currently a Senior Staff Research Scientist and head of Google Translate Research in Mountain View, CA. My research interests include machine translation, human and automatic evaluation of NLP systems, decoding strategies, model training, and data processing. Before joining Google, I worked as a Research Staff Member at IBM in Yorktown Heights, NY. I received my PhD in Computer Science from the RWTH Aachen University in 2015 under the supervision of Prof. Dr. Hermann Ney.
Current Research Interests
From 2021 onwards, we have primarily focused on researching better ways to evaluate the performance of NLP systems, either by humans or automatically via learned metrics. We have demonstrated that these improvements can be directly applied to NLP systems to improve their performance. For example, we can incorporate them as a utility/reward function into the inference algorithm. If you want to learn more about the importance of evaluation and how to use human feedback to improve NLP systems, you should watch my invited talk at the HumanEval 2022.
