09/2010 - 01/2015	PhD student at Institute for Mechanics, Otto-von-Guericke-University Magdeburg, Germany.
2004 - 2006	MSc in Physics, University of Pune, India. Major subjects: Nonlinear Dynamics, Methods of Computational Physics Master Thesis: Elastic Pendulum - Dynamical features of 2D elastic pendulum were studied in my master thesis project. It is important to use proper numerical integrator to study a conservative system. It is noticed that symplectic integrator (geometric integrator) is better than RK4 in capturing the dynamics of elastic pendulum. It preserves the volume in phase space. It is also noticed that the dynamic is regular at low and high energy levels, whereas it is chaotic at intermediate energy level. Resonance of oscillation happens due to the sharing of energy between swinging and springing motions.
