I am a Researcher Associate in Physics at CNEA and CONICET since late 2011. I belong to the Quantum Chaos Group. I am the head of the Theoretical Physics Department at  GIyA “Laboratorio Tandar” .


I am interested in Quantum Chaos, Complex Networks, Quantum Information,  Mesoscopic Physics, Transport Phenomena, and Complex Systems.

I’ve obtained my PhD in the Physics Department of Universidad de Buenos Aires with Marcos Saraceno as advisor.

I’ve spent two years in a ANR-CNRS postdoctoral position at Toulouse in the Quantware Group

(Dima Shepelyansky) at LPT in IRSAMC (UPS and CNRS).
