I am a Postdoctoral researcher in Computational Social Science at the Oxford Internet Institute (University of Oxford). I have several years of experience in collecting, processing and analysing massive amounts of digital trace data. Currently, I study collective memory based on the information seeking patterns of large number of individuals on the web. I also contribute to analyse the dynamics of disagreement by editors and bots in Wikipedia.

Our work so far has been featured on MIT Technology Review, The Guardian and Science. We have exposed in several international conferences on Computational Social Science.

During my PhD I studied how our culture/demographics influence the way we interact/behave online and how to use this information to provide better services online (i.e., recommender systems) and learn about societies (i.e., collaboration, discrimination, immigration, etc.).

Thanks to my stay at Yahoo Labs Barcelona during the 4 years of my PhD studies, I gained experience in processing large datasets in distributed computing environments (e.g., MapReduce, Apache Hadoop) as to identify how cultural differences influence the way people use, interact and generate content in social media (i.e., Twitter). To do so, I used tools such as Pig, java, R and python.

Outside of the lab, I love hiking, cooking, running and salsa dancing. I have ran several half marathons so far. I dream to be a marathon runner one day.
