RESEARCH FOCUS
I have been studying cellular and circuit-level changes in animal models of fear and anxiety via combining different approaches including electrophysiology, behaviour and pharmacogenetics (DREADDs). My current research focuses on identification of physiological and pathological alterations in the hippocampal activity patterns and their relation to modulation of hippocampal engrams in animal models of neuropsychiatric disorders. I am also interested in the impact of environmental factors and their interactions with immune system in mediation of affective behaviour.
