Based in London, United Kingdom · janoschhaber at gmail.com

I am a Senior Deep Learning Researcher with a focus on (large) language models and natural language processing (NLP).
My work experience includes customer feedback analysis at Chattermill, and hatespeech detection at Rewire.
Before that, I completed a PhD in Computational Linguistics at Queen Mary University of London (QMUL).
