Luis Dorfmann

Tufts University

USA

June 1 - Nov 30, 2012

Luis is interested in mathematical formulations to model the mechanical response of nonlinear elastic materials capable of large deformations. Specifically, he and his students are conducting research on the mechanics of elastic and inelastic rubberlike solids, in which the main focus is the development of constitutive theories to describe the mechanical behavior. Of special interests are inelastic effects such as stress softening, residual strains and the theory of pseudo-elasticity to account of the changes in material properties. Since 1994 an important theme has been the behavior of materials that rapidly change their mechanical properties by the application of an external electric or magnetic field. He is interested in constitutive models, which account for the finite deformation of highly deformable materials in the presence of an electromagnetic field and for the strong nonlinear coupling between electromagnetic and mechanical effects.


Garegin Papoian

University of Maryland

USA

June 3 - 16, 2012

Garyk uses advanced computational methods, based on theoretical physical chemistry, to study biological processes at multiple scales, from single protein functional dynamics and chromatin folding and stability to cell-level processes, such as cell motility: 1) Cell motility plays a key role in human biology and disease, contributing ubiquitously to such important processes as embryonic development, wound repair and cancer metastasis. Garyk is interested in gaining deeper understanding of the physical chemistry behind these complex, far-from-equilibrium mechano-chemical processes. His approach is based on combining stochastic reaction-diffusion treatment of cellular biochemical processes with polymer physics of cytoskeletal filament network growth, while explicitly coupling chemistry and mechanics. 2) The total length of DNA in each eukaryotic cell can reach 2 m, however, it must be housed in a micrometer size cell. This staggering six orders of magnitude compaction is achieved by wrapping DNA around protein octamers called histones, which then further fold into higher order chromatin structures. Garyk is interested in developing physico-chemical computational models to study the chromatin folding and dynamics using atomistic and coarse-grained approaches.
