The ultimate goal of our research is to reveal common mechanism and principles behind activity of complex biological systems, from cancer cell populations to brain neuronal networks, in normal and pathological states, and to develop clinical interventions that may prevent the development of pathologies. To achieve these goals, we apply a variety of methods – quantitative experimental techniques, sophisticated mathematical analysis and large-scale computer modeling – to a variety of problems to reveal common features across different biological systems. Our research is deeply collaborative; it involves interaction with experimental and clinical labs as well as collaboration with mathematicians and physicists.

Our work focuses on the following main areas: (1) Role of sleep in memory and learning. During sleep, the cortex is decoupled from sensory inputs, and can be devoted to consolidating previously acquired labile memories into stable memories. The goal of our research is to combine animal, human and computational works to explain mechanisms of sleep rhythm generation and how sleep rhythms contribute to memory consolidation. (2) Cellular and network mechanisms underlying the transformation of normal brain oscillations to electrographic seizures. The goal of this research is to design approaches that could be further developed to treat humans with trauma-induced epilepsy in clinical settings. (3) The role of neuronal oscillations and synchrony in olfactory coding — this project is targeted to discover the general principles and the neural circuitry involved in the encoding of sensory information in the brain. In collaboration with experimentalists, we construct detailed biophysical models of insect and vertebrate olfactory systems to study odor encoding, processing and learning. (4) Cancer treatment is complicated by drug resistance, drug efficacy, and relapse. The primary objective of our research on cancer is to use mathematical models to understand cancer cell dynamics, mechanisms of growth, and optimal treatment strategies.
