✨ News

✨ Nov/2021: Our team scored 1st and 3rd places at 2 tracks of BioCreative challenge (1st place for NER and 3rd place for RE track)
    - Lead our team (KU in collaboration with Richard Jackson from AstraZeneca) for the Relation Extraction (RE) - DrugProt task.
✨ Oct/2021: I am invited to present my research work on BioNLP at an internal conference hosted by AstraZeneca UK (More than a few hundred researchers accross the company and research institute attended the conference)
✨ May/2021: I gave an invited talk at a seminar hosted by RINS, Seoul National University (서울대학교 간호과학연구소) (News).
✨ Sep/2020: Our team (KU) won 8th BioASQ challenge PhaseB for both Exact and Ideal (Exact answers : for two consecutive years)
    - Lead our team for the ideal track this year, and the exact answer track for the last year (News).
✨ Sep/2020: BioBERT has been ranked as the most read papers in Bioinformatics which is one of the top-tier journals in the domain.
Also, BioBERT was included in the Best Papers for the Natural Language Processing Section of the 2020 IMIA (International Medical Informatics Association) Yearbook (link).


I am interested in Natural Language Processing and BioNLP.
My recent publications are focused on Language Models, QA and NER in biomedical domain.
(Please check: BioBERT (co-first author), BioASQ (BioASQ7b and BioASQ 8b).

I am also interested in Computational Biology.

Misc. I love taking pictures and traveling.
I took all the pictures in this webpage by myself!
Hope you enjoy them ; )
