Biography

Currently, I am a senior research associate at the University of Oxford (UK), and also a senior lecturer at the University of Oslo (Norway). I was responsible for the course IN3060/IN4060 Semantic Technologies in 2021 and 2022. I was a full-time IT (management) consultant at Boston Consulting Group from September 2022 to June 2023. 

From March 2019 to August 2019, I was a research associate at The University of Manchester (UK) and worked on the EPSRC IAA Project "Comparison and Abstraction of SNOMED CT Ontologies". Before that, I was a PhD student at Université Paris-Saclay/Université Paris-Sud (France). In June 2018, I was selected to attend French American Doctoral Exchange Seminar (FADEx) 2018  that organised by Mission pour la Science et la Technologie aux États-Unis. 

I received my master degree in the College of Computer Science, Jilin University (China).  From October 2013 to March 2014 , I was an exchange student in the master program of computational logic at TU Dresden (Germany) funded by the European programme Erasmus Mundus.
