My research consists in studying and developing computational techniques for extracting knowledge from complex systems/data. More specifically, my reasearch is focused on understanding and leveraging the similarities between many related learning problems, while also exploiting any available prior information on each problem.
I am currently working on structured sparsity models for making inferences from complex neuroimaging data, kernel methods for reinforcement learning and efficient optimization algorithms for large scale problems.

Keywords: statistical learning, supervised learning, kernel methods, structured sparsity, multi-output learning, reinforcement learning, convex optimization

Teaching

I assisted in the teaching of two courses for the UCL's MSc in Machine Learning.

For the Supervised Learning  course I gave a lecture on Multi-task Learning. You can find the slides HERE.

For the Advanced Topics in Machine Learning  course I gave a lecture on Proximal Methods. You can find the slides HERE.
