Education

Ph.D., Chemical Engineering, Pennsylvania State University, 1999
B. Tech., Chemical Engineering, Indian Institute of Technology, Bombay, 1993
Research Interests: 
  • Fluid Dynamics, Microfluidics
  • Predicting two-phase flow of Newtonian fluids is important in a variety of applications such as materials, polymer, and food processing, pharmaceuticals, and microfluidics. The interface between two fluid phases is often characterized by a single property, the interfacial tension. Variation of interfacial tension along an interface leads to tangential stresses that are known as Marangoni stresses. Temperature gradient or a gradient in concentration of surface-active agents (surfactants) along the interface leads to surface tension variation along the interface. Furthermore, if the bulk fluids exhibit viscoelasticity, they can store energy to some extent and display partial recovery upon removal of stress. The focus of this research is to understand the fundamental issues of how surface tension gradients affect free surface flows, how surfactants can be added to control flows, and how elasticity in the bulk phase changes the deformation and break up of a dispersed fluid phase.

Education

Ph.D., University of Rochester, 1984
B.S., Brigham Young University, 1980
Research Interests: 
  • Blood Rheology in Microvessel Networks, Cell Adhesion
  • My research focuses on blood rheology in microvessel networks. I am interested in Fahreus effect (reduction in blood cell concentration in small bore vessels), the Fahreus-Lindqvist effect (reduction in apparent viscosity in small bore vessels) and plasma skimming (the separation of cellular and plasma phases that occurs at the junction of small bore vessels. Currently I am working on a model of blood flow through networks which incorporate each of these rheological effects. Computational results present interesting nonlinear dynamics including fixed point attractors, limit cycles, and changes in the character and geometry of the attractor akin to period doubling. Experimental measurements are planned to verify these computational results.
