Claudia Vitolo is a hydrologist and data scientist with experience in developing tools and algorithms to facilitate the retrieval, modelling and visualisation of environmental data. She holds a PhD from Imperial College London and her thesis explored the use of data mining and machine learning techniques for hydrological modelling applications. She authored several R packages and prototyped a number of web applications for Environmental Virtual Observatories dedicated to water scarcity, climate change, hydrological modelling, and air pollution.  

Claudia likes to organise meetups in the data science field, hackathons, kaggle competitions as well as initiatives to support women in STEM. She co-founded R-Ladies Global, a world-wide organization to promote gender diversity in the R community. She is currently Chief Finance Officer of the R-Ladies Global organisation and a voting member of the R-Consortium Infrastructure Steering Committee.

Professional interests: 

Claudia's research interests are in the development of shared research environments to undertake environmental analysis and provide open access to predictions in data rich and data poor environments. She is passionate about new open technologies (e.g. databases, web services, etc.) and likes to explore their use in the context of environmental applications.
