Academic degrees

BSc ('07) and MSc ('09), both in Computer Science and Engineering, from the Instituto Superior Técnico (IST), the engineering school of the Technical University of Lisbon (TULisbon).

Research

I am a PhD student at IST and INESC-ID's Intelligent Agents and Synthetic Characters group. I work under the supervision of Prof. Andreas Wichert on neural coding techniques and associative memory. I am interested in efficient synaptic mechanisms supporting memory-related tasks such as information storage, robust recall or detection. My research is funded by a doctoral grant awarded by Fundação para a Ciência e Tecnologia (contract SFRH/BD/66398/2009).

My room and research colleagues are Luís Tarrataca and Ângelo Cardoso.
