RESEARCH
As a PostDoc researcher, I focus on the learning mechanisms that leads to enhanced replay sequential activity of an exploration and intrinsic factors determining the actual place field sizes in the hippocampus.
BACKGROUND
I completed my M.Sc. degree in Physics at the IASBS (Institute for Advanced Studies in Basic Sciences). My thesis research was mainly focused on visual memory representation in the primate visual system. As a PhD student in the Ruhr-university Bochum (RUB), I studied the network structures capable of generating intrinsic sequential activities in the hippocapus, and the robustness of the transformation from grid cells to place cells.

Bachelor's thesis, Applied Informatics, Univ. of Bochum, Germany.The Institut für Neuroinformatik (INI) is a central research unit of the Ruhr-Universität Bochum. We aim to understand the fundamental principles through which organisms generate behavior and cognition while linked to their environments through sensory systems and while acting in those environments through effector systems. Inspired by our insights into such natural cognitive systems, we seek new solutions to problems of information processing in artificial cognitive systems. We draw from a variety of disciplines that include experimental approaches from psychology and neurophysiology as well as theoretical approaches from physics, mathematics, electrical engineering and applied computer science, in particular machine learning, artificial intelligence, and computer vision.
