Research areas that are being pursued actively in the laboratory are broadly described under two categories: (A) Systems Biology, (B) Structural Bioinformatics, both combined towards addressing fundamental aspects of disease processes, obtaining global perspectives of perturbations in disease and application of that knowledge to tackle specific problems in disease diagnosis, drug discovery and immunology. A range of mathematical models, at multiple levels and scales are utilized for these.

How does our brain enable us to pay attention selectively to some things, and to ignore others? What happens in the brain when we make important decisions? Our research focuses on understanding the neural basis of cognitive phenomena such as selective attention and decision making. To address these questions we follow a quantitative approach that combines neuroscience experiments, model-based analyses (e.g., linear/nonlinear dynamical systems, control theory, machine learning) as well as large-scale computer simulations. We directly measure or perturb brain activity with a variety of techniques, including functional neuroimaging (fMRI), diffusion imaging (dMRI), high-density electro-encephalography (EEG), and transcranial electrical and magnetic stimulation (tES/tMS). The overarching goal is to develop a unified framework that describes how cognitive phenomena emerge from neural computations by a systematic analysis of brain and behavior.
