Research Achievements:

• The standard model for barrierless chemical reactions in solution would be a particle executing one-dimensional random walk on a harmonic potential, in presence of a delta function sink, located at an arbitrary position. An exact time domain solution to this model was proposed by us. This has been an unsolved problem for long time and is of considerable importance as a model for chemical reaction in solution.

• Two sate model for diffusion-reaction system deals with one dimensional random walk on two  potential wells in presence of coupling between them. Exact Laplace domain solution of this model for point-like coupling between two potentials was proposed by us. This is an interesting & important work in this field. Very recently we have proposed  an exact time domain solution of this same model, which was so far considered to be intractable.
