Sunetra Sarkar obtained her PhD from Indian Institute of Science, Bangalore, India and did her post-doctoral studies from Technical University of Delft, Netherlands. (see Sunetra Sarkar's professional background).
Her research interests lie in the field of dynamics of fluid structure interaction and unsteady flows. Over the years, a variety of problems related to this field have been studied, mainly through computational modelling of varied fidelities, and recently, using experimental techniques as well. One of the main focal points has been development of efficient numerical solvers, as the problems encountered were often nonlinear and needed to be characterized in a time accurate manner over large windows of time. These investigations have led to the resolution of the underlying bifurcations of the coupled systems as well as the flow-field vortex patterns. Novel flow-field wake modes and new bifurcation routes to fluid-elastic instabilities were reported which are of considerable interest to the community.
It was also recognized in her studies that the real life physical and engineering systems represented by the flow and fluid structure interactions problems could encounter sources of uncertainties. The coupled systems were known to manifest dynamical instabilities and presence of input uncertainties could potentially bring dramatic and sudden changes to their bifurcation requiring a careful reassessment of the problem in a stochastic framework. She has worked extensively on a variety of spectral based uncertainty quantification tools and have contributed towards the development of algorithms ideally suited for nonlinear fluid structure interaction problems.
