Dr. Lakshmanan has done outstanding work in the area of nonlinear dynamical systems. He has pioneered the use of group theoretic and differential geometric methods exploiting among other Painleve, Lie and Lie-Backlund analyses for exploring integrability and the existence of chaotic regimes. He has shown remarkable ability in inventing unsuspected transformations and finding new variables to expose hidden structures. His work on solitons in one dimensional Heisenberg spin chains in well-known. Dr. Lakshmanan's many faceted investigations in nonlinear dynamics have enriched the subject and have made a significant impact in the field.
