Biography

Niv completed a Master of Arts degree at
Tel-Aviv University Tel Aviv University (TAU) ( he, אוּנִיבֶרְסִיטַת תֵּל אָבִיב, ''Universitat Tel Aviv'') is a public research university in Tel Aviv, Israel. With over 30,000 students, it is the largest university in the country. Loc ...
in 2001. Her Master's thesis, was supervised by Daphna Joel and Eytan Ruppin and titled ''Evolution of Reinforcement Learning in Uncertain Environments.'' Niv received a Ph.D in Neuroscience at the Hebrew University of Jerusalem in 2008, where she worked under the supervision of
Peter Dayan Peter Dayan is director at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany. He is co-author of ''Theoretical Neuroscience'', an influential textbook on computational neuroscience. He is known for applying Bayesian m ...
on studies of behavioral control. Her dissertation was titled ''The Effects of Motivation on Habitual Instrumental Behavior''. After a post-doctoral fellowship at Princeton, Niv joined the faculty of the Princeton Neuroscience Institute and Psychology Department in 2008. Niv investigates the neural and computational processes underlying
reinforcement learning Reinforcement learning (RL) is an area of machine learning concerned with how intelligent agents ought to take actions in an environment in order to maximize the notion of cumulative reward. Reinforcement learning is one of three basic machine ...
—the ongoing day-to-day processes by which we learn from trial and error to maximize reward and minimize punishment. She studies signals in the brain that may reflect dual-control mechanisms underlying decision making, including an attention system in the
prefrontal cortex In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA ...
and a reinforcement learning system in the
basal ganglia The basal ganglia (BG), or basal nuclei, are a group of subcortical nuclei, of varied origin, in the brains of vertebrates. In humans, and some primates, there are some differences, mainly in the division of the globus pallidus into an extern ...
. Niv is interested in normative explanations of behavior and in developing neurocognitive models that offer principled explanations of brain mechanisms and their underlying computational algorithms. She asks in what sense, if at all, neurocomputational algorithms yield optimal decisions. From her perspective, the main goal of
computational neuroscience Computational neuroscience (also known as theoretical neuroscience or mathematical neuroscience) is a branch of  neuroscience which employs mathematical models, computer simulations, theoretical analysis and abstractions of the brain to ...
is ''not'' to simulate the system, but rather to understand what higher-level computations are instantiated in the brain, and the functionality of these neural computations.
