PhD Candidate Machine Learning and Natural Language Processing

I am an ELLIS PhD candidate at the University of Amsterdam working with Wilker Aziz, Barbara Plank and Raquel Fernández.

I am interested in understanding how large language models represent uncertainty, and if we can disentangle uncertainty that arises from the data (e.g., underspecified, subjective or ambiguous language) from uncertainty related to a model (e.g., lack of knowledge or reasoning). Ultimately, I think that uncertainty should power better decision-making.

I am part of the Dialogue Modeling Group in Amsterdam and MaiNLP at LMU in Munich. Previously, I interned at the Allen Institute for Artificial Intelligence in Seattle and spent a few years as ML engineer at DPG Media working on large scale news recommendation.



Occasionally I write blogposts. You can find them below.
