Me

I am an Assistant Professor at the Institute of Formal and Applied linguistics, Charles University in Prague, working on the NG-NLG ERC project (new methods for natural language generation). My main research focus is machine learning and deep learning for natural language processing, especially neural language models for natural language generation (NLG) and human-computer dialogue (dialogue systems, chatbots). I previously worked in the Interaction Lab at Heriot-Watt University in Edinburgh, where I also co-advised the Heriot-Watt University team in the Amazon Alexa Prize chatbot competition.

I did my PhD on language generation for dialogue systems at the Institute of Formal and Applied linguistics, Charles University in Prague, where I also worked on multiple grant projects related to dialogue systems and machine translations.
