| The
research interests of our group focus on multiphase, complex-fluid,
turbulent/chaotic and environmental systems. Studies range from
nanoscale problems, e.g. spinodal decomposition in shear flows,
coalescence, and flow interactions with macromolecular structures
like cell-membrane receptors and channels, to macroscale problems
like turbulent transport processes at the air-sea interface, of
importance in global warming. Some applications are to a environmental
processes (PDF
paper), development of complex/multiphase fluid formulations(PDF
paper), and mesoscale transport phenomena in biological systems(PDF
paper) . An example of work in the last area is transport
and transduction processes in neo-vascularization.
Experimental techniques involve
Laser-Doppler Anemometry, Particle Imaging Velocimetry, as well
as flow and molecule-specific imaging based on Atomic Force Microscopy.
Simulation/theoretical approaches are based on spectral methods
using level-set and self-consistent field theory (SCFT) models.
We, together with Profs. Frederickson and Ceniceros, have founded
the Complex Fluids Design Center (CFDC) [insert website] at UCSB.
The work is supported by DOE Basic Energy Sciences, the National
Science Foundation, NASA, Los Alamos National Laboratories and
several industrial organizations.
