Research Interests: 

I'm interested in the neural substrates of spatial navigation in rats in a challenging spatial task called ‘the Traveling Salesperson Problem’ (TSP). In this task, subjects have to find the optimal shortest route between a specific set of rewarded locations. This task has been extensively studied theoretically in Engineering, Robotics and Computer Science and has been shown to be essentially unsolvable unless ‘brute force’ is used (i.e. exploring all possibilities, choosing the shortest). However, our laboratory published evidence that rats were capable of approximating the optimal solution in less than 10 trials, naturally, with almost no prior training. How rats (but not computers) achieve this task, and the role of awake hippocampal replay in this optimization process are completely unknown.

I finished my Ph.D. in 2015 in Prof. Matti Mintz laboratory at the Tel-Aviv University.During my Ph.D. work, I have studied hippocampal mechanism of dinamic environment encoding in rats, using electrophysiology and computational methods. After completing my Ph.D studies, I joined the Computational and Experimental Neuroscience Laboratory of Dr. Jean-Marc Fellous (http://amygdala.psychdept.arizona.edu/lab.html) and began my Post-Doctoral research at the University of Arizona.
