We are interested in understanding nature and in converting our understanding into useful devices for humans.
In the world of submicrons to millimeters, capillary forces usually dominate over other forces. Given a fluid or solid object of size L, capillary forces are in general proportional to L, whereas surface and body forces vary as L2 and L3, respectively. Thus, as L decreases, surface tension becomes increasingly important. It is therefore not surprising that many natural phenomena and industrial processes are governed by capillarity. We have studied evolution and stability of solid thin films, micro and nano liquid films and threads, two-phase flow and heat transfer in microchannels, and dynamic surface tension. Details can be found on my personal webpage listed below.
Currently, we are investigating heat and mass transfer in micro heat pipes and giant heat pipes. We are also studying morphological stability of micro and nano wires.
