Dr. Refael Tikochinski

I am a cognitive neuroscientist and a fellow of the Israel Council for Higher Education. I am interested in the way semantic information is organized and represented in the human brain, and how this organization helps individuals build their own mental models of the world. Specifically, I investigate how exposure to new knowledge influences internal mental representations and the subsequent effects on future information-seeking behaviors. I use advanced computational research methods, primarily from the field of Natural Language Processing (NLP), alongside more “classical” behavioral and neuroimaging methods from the field of psychology.

I completed my PhD at the Technion – Israel Institute of Technology in Haifa, Israel, under the joint supervision of Prof. Roi Reichart (Faculty of Data and Decision Sciences, Technion) and Prof. Uri Hasson (Princeton Neuroscience Institute, Princeton University). My PhD dissertation focused on various uses of large language models (LLMs) to investigate how the human brain incorporates context and perspectives into language processing. Prior to that, I completed my Bachelor’s and Master’s degrees in Psychology at the Hebrew University of Jerusalem, Israel.
