I’m a PhD candidate at UniMelb, very fortunate to be advised by Lea Frermann and Tim Baldwin. My thesis focuses on exploring ways to automatically find biases in the narrative of news articles. I consider myself a computational linguist, who likes to dance, read and discuss about general things. I love the idea of combining languages and computer science, therefore NLP is one of my passions.
Work experience
My (current) main interest is fairness in news data. But I like to keep an eye in many other topics like: automatic fact checking (afc), question answering, generation. Dialogue systems will be probably my first love for ever.
Before my PhD, I worked as a researcher in the UKP Lab at the TU Darmstadt. Prior to that, I was a machine learning consultant at Novatec GmbH, a company with headquarters in Leinfelden Germany. There, I worked on prototyping solutions for different clients and helping with the design of workshops and lectures about machine learning. Previous to that I interned for several companies, including Mercedes Benz in Germany and in CA, USA, Sony Deutschland GmbH and Compart AG in Böblingen Germany. For more details see my cv here.
