Research interests

  • rheology and dynamics of complex and biological fluids and suspensions
  • mesoscopic simulations of complex fluids and biological systems
  • red blood cells and blood flow modeling in health and disease
  • multiscale modeling bridging atomistic-mesoscopic-continuum scales
  • numerical rheometry

  • high-performance computing


Research experience

Sep 2004 - present Research Assistant, Division of Applied Mathematics, Brown University
Advisors: George E. Karniadakis & Bruce Caswell
My research focuses on the modeling of complex and biological fluids and the development of multiscale methods suitable for such systems. I have extensive experience in atomistic and mesoscopic (MD and DPD methods) and in continuum (spectral/hp element and FEM methods) modeling. My recent work is on the simulation of red blood cells and vesicles, blood flow, and rheology in health and disease. I also work on the development of methods for efficient multiscale algorithms which couple together atomistic, mesoscopic, and continuum descriptions. In addition, I have been working on the modeling of complex fluids which involve polymer suspensions ranging from dilute and semi-dilute solutions to melts. This includes numerical rheological measurements of their properties and fluid flow simulations. Finally, I acquired extensive experience in high performance computing.
Sep 2002 - Aug 2004 Research Assistant, Department of Aerospace Engineering, Pennsylvania State University
Advisor: Deborah A. Levin
My research focused on the rarefied gas flow simulations using the DSMC method. In addition, I worked on the thermal conduction in a micronozzle via FEM simulations.
