Research Scientist at Cohere for AI
I’m a research scientist at Cohere for AI, where I conduct research on large language models, centered around multilinguality, reinforcement learning, and evaluation. Previously I worked at Google Research, Montreal, with a focus on machine translation. Very broadly speaking, I am interested in the intersection of natural language processing (NLP) and machine learning, especially where multiple languages come into play.
In my PhD (Heidelberg University, Germany) I investigated how reinforcement learning algorithms can be used to turn weak supervision signals from users into meaningful updates for a machine translation system (=RLHF before it was cool). More recently, I have focused on improving multilinguality, language diversity and data quality in machine translation and related applications.
My long-term goal for NLP research is to make it more accessible, along multiple dimensions:
