Research Interests
I am interested in polymer dynamics, pattern formation and working
with experimental groups on biophysical studies.
In polymer dynamics, I am studying the role
of reactions in polymers. For example, the formation of ring polymers due
to reactions between polymer endgroups and the reactive compatibilzation of
polymer blends which effects the adhesive properties of polymer interfaces.
My research involve undergraduate students and are introduced to both analytic
and computational tools.
I am also studying the dynamics of pattern
formation in a variety of systems such as the formation of magnetic domains
after a rapid quench, flow in porous media (such as water pushing out oil
in sand), and laser induced melting of silicon films.
A computer simulation of the domain coarsening of a magnetic system
after a rapid quench:
The times are (clockwise from top left corner) t=1000, t=4000, t=16000 and t=65000
iterations after the quench.
