I am a Computer Scientist in the Center on Knowledge Graphs within the Information Sciences Institute (ISI) at the USC Viterbi School of Engineering. My mentor is Pedro Szekely. I hold a Ph.D. in Natural Language Processing from the Vrije Universiteit (VU) in Amsterdam. My principal research interest concerns the role of background knowledge for filling gaps in human communication. I am leading the development of the Commonsense Knowledge Graph (CSKG), a resource which consolidates existing sources into a harmonized representation. CSKG allows us to enhance language models for zero-shot Question Answering with more knowledge, precisely select relevant subsets, or perform explainable inference. I am also heavily involved in the development of the Knowledge Graph ToolKit (KGTK) - a comprehensive set of operations for working with modern, hyperrelational graphs like Wikidata. In the past year, I worked together with around 10 Ph.D. and Master students, and collaborated with researchers at CMU, Bosch Research, RPI, etc. We have been publishing this work in top-tier venues like AAAI, EMNLP, and ISWC.
If you are:
- a driven and knowledgeable student, interested to work on these topics as research assstant, or
- a researcher, interested in discussing new and exciting collaborations
