Welcome to the Complex Materials Theory Group!
Our research group is based at Princeton
University in the
Department of Chemistry,
the
Princeton Institute for the Science and Technology of Materials, and the Princeton Center for Theoretical
Science. We also have affiliations with four other departments
/programs: Physics,
Applied and Computational Mathematics,
Chemical Engineering,
and Mechanical &
Aerospace Engineering. We are generally interested in understanding
the relationship between the macroscopic behavior of complex materials
and their microstructures. Complex materials under study include heterogeneous
materials (e.g., composites and porous media), colloids, liquids, glasses and
crystals. This includes our current work on
disordered and ordered particle packings in low dimensions (including M&Ms,
ellipsoids, and superballs), sphere packings in high dimensions, optimal multifunctional
material design,
self-assembly theory, and unusual ground states.
We are also engaged in a research program to model tumor growth.
