I am a Senior Machine Learning Scientist at Huawei R&D Center Amsterdam. I work on training Huawei’s ChatGPT models, and am responsible for the Reinforcement Learning algorithm development and model training. More broadly, my work involves chatbots, information retrieval and conversational QA systems. In parallel, I am completing my PhD at the University of Amsterdam, under the supervision of Prof. Maarten de Rijke. In the past, I did two internships at Replika.ai and Amazon.com, respectively.
