Hi ! Welcome to my page.
I am a faculty member of the Theoretical Physics group, Institute of
Mathematical Sciences (IMSc) at Chennai (formerly known as Madras).
I did my Ph.D. on the nonlinear
dynamics of recurrent neural network models from the Machine Intelligence
Unit, Indian Statistical Institute, Calcutta (1998). I then did postdoctoral
research on nonlinear dynamics of spatially extended systems with
focus on biological systems at the Indian Institute of Science at
Bangalore (1998-2000 and 2001-2002) and Weill Medical College of Cornell
University at New York City (2000-2001). I joined IMSc in September 2002.
My areas of research fall broadly under nonlinear dynamics, complex
systems and theoretical & computational biophysics. Particular
topics in which I am currently working include:
- Physics of cardiac arrhythmias - spatio-temporal dynamics of
spiral waves and spiral turbulence in excitable media - pattern formation
in biological cells and tissue
- Network dynamics - stability vs. complexity issues in small-world
networks with application
to ecology - eigenvalue statistics of non-hermitian random matrices
- non-equilibrium statistical mechanics of community assembly models
- Physics of social and economic phenomena - emergent scaling behavior
(e.g., Pareto law of wealth and income distribution)
in random asset exchange models - phase transitions in
collective (or social) choice relevant to financial markets,
movie revenue distribution and electoral behavior
- Emergence of computational complexity in cellular automata and
related systems - Phase transition in SAT-like problems
- Neurodynamics - non-equlibrium neural network models - application
of chaos to information processing - modelling low-level visual processing
in the retina
- Stochastic resonance, critical behavior and hysteresis in simple
maps arising in biological contexts
