Current research interests include: synaptic function of the CNS neurons and astrocytes; morphological and functional plasticity of the “tripartite” synapse; protein targeting, trafficking and membrane insertion/removal mechanisms; intracellular Ca²⁺ dynamics; mitochondrial signaling and ROS-dependent modulation of synaptic function; glial-neuronal bidirectional signaling and roles of astrocytes in generation, maintenance and plasticity of synapses; KCC2-mediated intracellular Cl^- regulation in dendrites and axons.
