: Nonlinear Dynamics, Granular Segregation, Granular
Hydrodynamics, Fracture of Thin Sheets.
I am currently a Post-Doc in Mark
. My scientific interests lie in the
general area of nonlinear dynamics of systems driven far from
equilibrium, which I probe primarily with experiments. Over the last
few years I have developed particular interest on the physics of Granular
which is far from understood. During
my Ph.D. I focused my attention on Granular Segregation. This is
an interesting and counter-intuitive issue of binary mixtures,
where an initially uniform mixture of particles can spontaneously
de-mix under flow. Here in New York, I am currently developing an
experiment where a quasi-2D granular fluid is created through
vibration. We are using this system to study the validity of
kinetic theory and to explore hydrodynamic-like phenomena. Another
area that I have fun with is the fracture of thin elastic sheets.
In collaboration with Benoit Roman
and Basile Audoly
currently studying the oscillatory fracture
while tearing a thin polymer film (e.g. the film packaging in a
new CD case) with a rigid object (e.g. a pen).
