My name is Sampo Pyysalo, and I am a research associate at the Language Technology Lab (LTL) at the University of Cambridge. My research is on natural language processing with a focus on biomedical text mining, in particular machine learning for information extraction.

I'm recently working mostly on event extraction from biomedical scientific publications, both organizing the BioNLP Shared Task series of events and participating in efforts applying information extraction methods to automatically analyze the entire available literature. I've also been contributing to the Universal Dependencies (UD) effort, including the UD Finnish dependency treebank.

For my publications, please see my google scholar page.
