An image by doctoral student Birendra Jha appeared in the October 2011 issue of Wired-UK magazine and the September 2011 issue of Discover magazine. The image was taken from a computer simulation of viscous fingering, which Jha and co-authors used to show the mixing of two liquids when a low-viscosity fluid is injected into a higher-viscosity fluid in a confined space, such as a microfluidics device or an oil reservoir. Professor Ruben Juanes, postdoctoral associate Luis Cueto-Felgueroso and graduate students Jha and Michael Szulczewski co-authored a paper on the subject that appeared in a May issue of Physical Review Letters.
