Hi! I am a postdoctoral fellow working at the
Materials Research Laboratory of the
University of California, Santa Barbara
under the direction of Professor Glenn Fredrickson.
My research interest is the mechanical, dynamical and structural properties of "soft" materials, in particular polymers.
Currently I am studying thermoreversible "associating" polymer networks.
These systems are intermediate between simple melts and "chemical gels" (i. e. rubber); their supramolecular structure is formed by temporary interchain bonds.
I am concerned mostly with their behavior above the glass transition, where these systems fall under the general category of "complex fluids".
On short time scales these deform elastically, while at longer times they flow like viscous fluids.
The reversibity of the bonds makes this behavior is considerably more complicated that that found in either chemical gels or simple melts.
I study these systems using hybrid molecular dynamics / Monte Carlo simulations with a modified version of the LAMMPS package. My past and current research is described on my CV. |
