Moriel Zelikowsky

Moriel Zelikowsky is a neuroscientist at University of Utah School of Medicine. Her laboratory studies the brain circuits and neural mechanisms underlying stress, fear, and social behavior. Her previous work includes fear and the hippocampus, and the role of neuropeptide Tac2 in social isolation.

Early life and education Zelikowsky was raised in Los Angeles and earned her bachelor's degree in Philosophy in 2006 from UCLA. Originally, Zelikowsky started out as a film major until she took a few metaphysics classes. After deciding she was more interested in tangible answers to questions such as "what is the brain?" or "how do we think?" that she asked during philosophy classes, she started taking neuropsychiatry classes and applied to P.h.D programs in Psychology. She joined the laboratory of Dr. Michael Fanselow at UCLA, which studies behavioral neuroscience, specifically fear learning and how fear memories are stored in the brain. Her thesis work showed that a dynamic circuit composed of the amygdala, hippocampus, and prefrontal cortex contributes to fear learning and extinction in a context-sensitive manner. Her work was published in the Journal of Neuroscience and was awarded the New York Academy of Sciences Cattell Award and the Gengerelli Distinguished Dissertation Award. She received her P.h.D in 2012.

Career and research After receiving her P.h.D, Zelikowsky worked a postdoctoral fellow in the lab of Dr. David J. Anderson in the Department of Biology and Biological Engineering at Caltech. In an interview with L'Oréal USA For Women in Science, Zelikowsky explained "The brain undergoes significant change following an intense emotional event, and these alterations in neural processing and dynamics give rise to maladaptive behaviors. It is my hope that my research will contribute to a global shift towards increased cellular precision in our approach towards the treatment of mental health disorders". A significant portion of this research focused specifically on social isolation and Tac2 and its influence on behavior. As a postdoctoral fellow, Zelikowsky was supported by multiple awards and fellowships, including the National Science Foundation, a NARSAD Young Investigator Award, a LOREAL for Women in Science Award, Zelikowsky was recently awarded a 2020 Sloan Research Fellowship in recognition of "creativity, leadership, and achievements in research".

In addition to her research, Zelikowsky also founded a group called Women in Learning which aims to provide a way for students and postdoctoral fellows studying learning, behavior, memory, and the broader field of neuroscience to find support and guidance on the promotion of female researchers from notable women already established in the field.
