Ana Claudia Sima

Affiliated Senior Researcher

SIB Swiss Institute of Bioinformatics

My main research interest is in the impact of Semantic Web Technologies for the Life Sciences, particularly in Semantic Search over Knowledge Graphs. I enjoy working at the boundary between disciplines as part of collaborations with both academia and the industry. During my PhD I designed and implemented Bio-SODA, a Question Answering system over Bioinformatics Knowledge Graphs, as part of an SNF-funded NRP-75 “Big Data” project between the ZHAW, UNIL and SIB. More recently, I have started investigating the role of Large Language Models in democratizing data access to scientific Knowledge Graphs.

I am currently co-leading the Knowledge Representation Unit at SIB, with the mission of improving scientific data exchange and reuse in Switzerland and worldwide, particularly in Bioinformatics. P.S.: I speak SPARQL  and I enjoy taking part in hackathons and hiking.
