Research Interests
I am an experimentalist working on the nonlinear dynamics of extended systems. Currently, I am studying various aspects of liquid drops – on impact with a liquid layer, self-levitated (the Leidenfrost effect), and rectified motion under vibration.
I'm also investigating pattern formation in vibrated shear-thickening fluids, singularity dominated fluctuations of light refracted through a wavy surface, and the biomechanics of seed dispersal.
Research Themes
Sample Research Topic
Persistent holes in fluids
We have recently discovered that vibrated shear-thickening fluids – which become more viscous with increasing shear rate – can support holes and develop large finger-like protrusions.
