I am Bernardino Romera-Paredes, currently Postdoc at University of Oxford, having recently finished my PhD at University College London (UCL). My research is focused on building user-dependent models for affect and expression recognition by combining and extending multilinear and multi-task learning methods. These models have been successfully applied to a variety of scenarios beyond affect recognition, in which data sets can be arranged into meaningful multi-modal structures. This research has led to publications in top-tier machine learning conferences such as NIPS, ICML and AISTATS, as well as interaction based conferences, such as Affective Computing and Intelligent Interaction (ACII) and Face and Gesture (FG). I received the Best Paper Award at ACII 2013 and the Best Paper Runner-up Prize at ICML 2013, among others.

In 2013, I did an internship at Microsoft Research in Redmond, where I investigated about the 3D reconstruction of facial expressions from video captured head-mounted cameras.

Prior to my PhD, I finished with honors Bachelor's Degree in Computer Engineering at the University of Murcia and completed with distinction the MSc Computational Statistics and Machine Learning at UCL.
