Bio

I’m currently Research Scientist at the Applied Artificial Intelligence Lab, Compute Science Institute (FCEyN, UBA – CONICET), Professor at the Computer Science Dept., Compute Science Institute (FCEyN, UBA), and head of the Master on Data Mining  (FCEyN, UBA). 

I completed my undergraduate thesis in Physics studying adult neurogenesis with Alejandro Schinder (Neuronal Plasticity lab, Fundación Instituto Leloir). I continued my research path combining Physics and Neuroscience during my PhD, studying the organization of cognitive processes with Mariano Sigman (Integrative Neuroscience Lab, Physics Dept., FCEyN, UBA) where we started co-registering EEG and eye movements. This was pioneering work in an emerging field, showing for the first time a comparison between free eye movement and fixed gaze ERPs and paving the way for studying brain activity in naturalistic scenarios. During my posdoc, we worked in collaboration with Sebastián Lipina (Unit of Applied Neurobiology, CEMIC-CONICET) studying the impact of socio­economic variables on brain processes underlying cognitive control in children in contexts of social vulnerability. Finally, in 2013, I moved to Computer Science Department as a researcher, I carried out my research activities as PI or Co-PI of several funded grants; and supervised or co-supervised graduate and undergrad theses in Computer Science, Physics, Biology, Engineering, Psychology, and Lingüistics.

Research Interest:

My main research focus is on studying brain activity during naturalistic tasks. On the one hand, we use M/EEG, eye tracking, and computational models to study how the brain combines local and global information along a scanpath throughout an image or text. And, on the other hand, we study the impact of socio­economic variables on brain processes underlying cognitive control in children in contexts of social vulnerability, developing tools to be able to measure outside the lab.
