I have graduated from Instituto Superior Tecnico, Portugal in Applied Mathematics and Computation both Bachelor and Master levels.
My master thesis was taken at the Vislab - Computer and Vision Lab, Institute for Systems and Robotics, with Alexandre Bernardino in space variant vision. We developed a new method to implement and manipulate foveated images, i.e. images with higher resolution in the center than in the periphery of the field of view (as in the primate eye, where retinal image has higher resolution in the fovea).
From 2009 to 2014, I was a PhD candidate at the Frankfurt Institute for Advanced Studies. I was working with Constantin Rothkopf and Jochen Triesch on the modeling the variability of Retinal Ganglion Cells directly from the statistics of naturalistic images across the field of view.
From 2014 to 2016, I was a postdoc
at the Biovision team, INRIA Sophia Antipolis, working with Pierre
Kornprobst  and Bruno Cessac . We were working in
methods for analysing (retinal) spiking data. At the single cell level, we have
proposed a new stimulus for an efficient estimation of receptive fields, the
shifted stimulus. At the population level, we worked in a method that assuming a leaky-integrate-and-fire model it learns the population connectivity from an empirical raster.
Since 2017, I am a postdoc at U2IS,
ENSTA-ParisTech, working with Antoine
Manzanera. We are working in life long learning of visual
representations, particularly in the problems of incremental learning and
We are looking for interns, master students and PhD students. If you would like
to work with me and Antoine Manzanera, whether you have an idea or not, just
send me an informal email with your research interests and your availability.
