"Understanding the Hydrodynamics of Drops in Microfluidic Networks for High Throughput Analysis "


Droplet-based microfluidics where reactants or biological species are encapsulated in thousands of tiny water droplets is witnessing a tremendous interest for applications in chemistry, biology, medicine and material science. To enable the development of robust droplet-based devices, my laboratory has been investigating the dynamics of confined drops in a special class of fluidic networks called microfluidic parking networks. These networks consist of a repeated sequence of loops, with each loop containing a fluidic trap to park drops. In this talk, I will discuss how we harness collective hydrodynamics of drops to engineer multi-functional microfluidic devices. I will also present some counterintuitive phenomena associated with squeezing and coalescence of parked drops; and highlight the underlying hydrodynamic mechanisms. Finally, I will discuss our efforts to translate these inexpensive microfluidic platforms for high throughput analysis in material science and biology.


I graduated with a PhD in Chemical Engineering in 2006 from the University of Michigan under the supervision of Prof. Michael Solomon. I did a postdoc in the Physics of Complex Fluids group at the University of Twente. I joined as an Assistant Professor at Texas Tech University in 2008 and got tenured and promoted to Associated Professor in 2014. I am currently the holder of the Bill Sanderson and Ed & Linda Whitacre Faculty Fellowships at Texas Tech. I received the NSF CAREER Award, Rising Star Award from the Cell & Molecular Bioengineering Section of the BMES, and the Chancellorís Distinguished Council Research Award at Texas Tech.
