As a computer science researcher I am interested in machine learning and mainly in applications in natural language processing and understanding. I am also interested in information retrieval and recommender systems.

As a software engineer I hate working on already existing projects without making an impact. I like working on novel ideas from scratch that can change the world and improve our daily life.

As a human I like travelling, tasting food and meeting smart people with great ideas.
