RESEARCH INTERESTS

Rotha is currently working on phase imaging in generalized aberrated optics with an aim to develop generalized imaging systems for high resolution optical imaging.

Rotha's previous work was on the inverse problem of inferring the evolution equation from modulus information. The work leads to successful development of an iterative scheme for inferring the equation of evolution of complex systems obeying the time-dependent complex Ginzburg-Landau equation.

Rotha's PhD work was on Numerical Simulations of Topological Defects in R(2+1), R(3+1) and R(4+1) Spacetime. The works were on numerical simulations of cosmic strings, domain walls and monoples in the Big Bang model of the Early Universe. Numerical simulations were also on vortices in the postulated dark matter condensate in the galaxies.
