About me

I'm Diego Sáez Trumper. I joined the Wikimedia Foundation in August 2017 as part of the Research team. I'm from Chile, currently based in Barcelona.

My work

My background is on Social Networks Analysis, Graph Theory and applied Machine Learning. At the WMF my work focuses on using data science tools to Improve Knowledge Integrity and fighting disinformation with Wikipedia by generating scientific knowledge as well as building large and efficient Machine Learning models to support our communities.
