The research interests of Zvonimir Dogic and his group lie in elucidating rules that govern self-assembly of materials, with a particular emphasis being placed on the role the particle's shape and chirality play in these assembly processes.  We strive to create very simple model systems in which precise control is possible over all the relevant parameters.  This enables a rigorous and detailed comparison with theoretical predictions.  The particles we use have very simple hard core repulsive interactions.  Despite the apparent simplicity of these building blocks, we have demonstrated that through a careful choice of particle shape and chirality it is possible to assemble at least half a dozen unique structures.  By necessity our research is highly interdisciplinary.  To accomplish our goals, in addition to a host of experimental techniques, we also utilize theoretical statistical mechanics, computer simulations, biochemistry, various protein purification techniques and molecular cloning.
