I am a researcher at the Oxford e-Research Centre currently working as a knowledge engineer with Prof. Susanna-Assunta Sansone in the area of data management for biomedical sciences. I apply data analytic techniques to enrich the data/publications repositories and platforms that we have under the FAIR ( Findable, Accessible, Interoperable and Reusable) principle.

I held previous positions as a Research Assistant at the Centre working in the following areas:

1) Energy analytics, where I worked with Prof. David Wallom. We applied machine learning and data mining techniques to solve problems such as clustering of energy profiles and prediction of electricity demand. In my last project we tried to predict the typical electricity and gas behaviour of a new supermarket combining the consumption of similar supermarkets. Before that I I worked on the WICKED project where we investigated how to cluster electricity load profiles with both Bayesian and frequenstist algorithms. I have also worked in analysing and predicting which businesses would obtain economic benefit when they change from static tariffs to dynamic tariff.

2) Computational linguistics, where I worked with Prof. Janet Pierrehumbert. We investigated word formation (prefixation and suffixation) on the Wordovators project. We used deep learning embeddings to represent and model the words and their relationships.
