Research Interests

vortices

Most fluid flows of interest, in both nature and industry, are nonlinear and exhibit complex multi-scale dynamics, including pattern formation and turbulence. My research group addresses such fluid flow problems in a variety of contexts, including pulmonary mucus dynamics, multiphase flows in microchannels, polymer scission in turbulence, and pattern formation in biological and geological settings. For more information about our current work and open research positions, please visit our group webpage: https://www.che.iitb.ac.in/group/picardo-group.
