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.

Research Interests: 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.

Research interests: Our lab studies the neural and computationalbasis of movement planning and control with an emphasis to understand the basis of flexibility and control that is the hallmark of intelligent action. From the perspective of behavior we seekto understand the nature of computations that enable motor control; from the perspective of the brain we seek to understand the contribution of circumscribed neural circuits to motor behavior; and by recording the electrical activity of neurons and muscles we seek to understand how such computational processes are implemented by the brain. Our research interests span the fields of visual perception, decision-making, and the generation of motor behavior and involve the application of cognitive/psychophysical,neuropsychological and electrophysiological techniques.

Prof. S. K. Nandy's current research addresses important issues in micro-architectural and compiler optimizations for power and performance in Chip Multiprocessors (CMPs) and Runtime Reconfigurable System on Chips (MP-SoCs). All his research target massively parallel architectures/platforms for accelerating computations for Next Generation Sequence Alignment, Numerical Linear Algebra, Real-time Face Recognition, Cognition Engines, and Molecular Dynamics. 


Radhakant Padhi


Research interests:  Development of innovative algorithms to solve optimal and nonlinear control synthesis problems, followed by applying those to challenging real-life problems is the main focus of our lab. Techniques developed in our lab so far include model predictive static programming and its various variants, single network adaptive critic, optimal dynamic inversion, generalized dynamic inversion, neuro-adaptive design etc. Application areas in aerospace include guidance and control of missiles, spacecrafts, lunar lander, aircrafts and UAVs. In bio-medicine, our focus has been computer controlled automatic drug delivery using feedback control theory and also deciphering the control activities of human brain. The feedback drug delivery philosophy has been demonstrated to work well (from in-silico experiments) to effectively cure various cancer problems. An important current research focus is to develop an adaptive and customized artificial pancreas system for Type-1 diabetic patients. Other problems of interest to our lab include path planning and guidance of ground vehicles, vibration control, temperature control, process control etc.

Recent studies have identified a small subpopulation of cells within several cancers termed as cancer stem cells (CSCs). These CSCs play critical roles in tumor initiation, progression, and maintenance. Furthermore, CSCs remain unaffected by currently used chemotherapeutic drugs, thereby leading to chemotherapy failure and cancer recurrence. The research focus of my laboratory is to understand the unique molecular mechanisms operating within CSCs, and find novels ways for targeting them. Work done in my laboratory has identified AMP activated protein kinase (AMPK) as a key signaling molecule in the regulation of breast cancer stem-like properties, survival and drug resistance. Current interests are in understanding the molecular mechanisms downstream of AMPK activation that contribute to cancer progression.

Email: sray@iisc.ac.in

I received a B.Tech in Electrical Engineering from IIT Kanpur and a PhD in Biomedical Engineering from the Johns Hopkins School of Medicine. My postdoctoral training was in the department of Neurobiology at Harvard Medical School with Dr. John Maunsell. I joined the Center for Neuroscience, IISc, in June 2011. From 2012 onwards, I have also been an associate faculty in the Electrical Engineering Department at IISc.
Our lab studies the neural basis of selective attention, with a focus on a brain rhythm called “gamma” (30-80 Hz), which is modulated by attentional load and is thought to be linked to high-level cognitive processes. Attentional mechanisms have been studied at several different recording scales – from single neurons in monkeys to diffuse population measures such as electro-encephalography (EEG) in humans. However, the relationship between signals recorded from such different scales is poorly understood. The long-term goal of this research is to elucidate the mechanisms of attention by linking the neural recordings obtained from these vastly different scales. This involves recordings from both humans and non-human primates using a variety of techniques while they are engaged in certain cognitive tasks, development of advanced signal processing techniques to build the “links” across recording scales, and mathematical modelling of brain signals, including gamma oscillations, using dynamical system approach as well as detailed biophysical models. Establishment of this cross-species, cross-scale link between brain signals has far reaching applications, such as in Brain-computer Interfacing (BCI) and clinical diagnosis of brain disorders.

Research Interests: Mechanisms of attention and gamma oscillations; Modeling and Signal Processing, Brain-Computer Interfacing.
