Joined NIAS on: 10th July 2012.
Most significant research contribution: Recent focus areas have been on studies of Complex Systems.
Dr. Janaki Balakrishnan anchors the Complex Systems Programme in the School of Natural Sciences & Engineering at NIAS. She obtained her PhD in Theoretical High Energy Physics from the University of Delhi. She has subsequently worked and published in a wide range of areas covering many diverse areas of physics, ranging from quantum field theory in curved space and theoretical high energy physics to dynamical systems theory and biological physics. She was an Associate Professor of Physics at the Central University of Hyderabad for several years before moving to Bangalore. Earlier she has held Visiting and other positions at various places including the Institute of Mathematical Sciences, Chennai, Centre for Artificial Intelligence & Robotics (CAIR), Bangalore, CMMACS, Bangalore, JNCASR, Indian Institute of Science, Raman Research Institute, The University of Newcastle-upon-Tyne, U.K., Max-Planck Institute for Mathematics in the Sciences, Leipzig, Germany, the Max-Planck Institute for the Physics of Complex Systems, Dresden, Germany, etc.
Research Interest:
Dynamical systems theory and its applications to physical, biological & real world problems, complex systems, bubble dynamics, acoustic cavitation, ecological modelling, physics of sensory systems, synchronization of neuronal activity, bursting behaviour in neurons,stochastic processes, quantum field theory in flat & curved spacetimes.
