Research Activities

Representative research topics are formulated on the BSS Research interests list (but not updated very often).   My (and all BSS) publications are accessible on the searchable (and downloadable) database BSS Publications (which gets better and more comprehensive all the time).   The Thomson-Reuters (Web of Knowledge) maintain my ResearcherID link -- button on the right.

With Mark Warner, we have written a monograph "Liquid Crystal Elastomers". From the book's website you could download the first Chapter, called "The Bird's Eye View", which is an overview of the new physics arising in this field; the Appendices of the paperback edition are also downloadable there.

I am involved in a number of projects in a broad area of soft condensed matter and biological physics. The list is long and changing all the time depending on the current fashion, unexpected discovery, external collaboration, funding, or just a chance. However, a few areas are big enough and with a sufficiently long half-life:

  • Mechanics of cells and tissues. This area is being "revived" with the rise of Physics of Medicine (see above). We look theoretically at the mechanisms of mechano-sensitivity: how the cells and confluent tissues respond to changes in mechanical characteristics of their environment. A current experimental projects examines how fascia and other ligamentous tissue responds to strain: to maintain homeostasis there has to be an active recovery exerting a force higher than the one originally applied - but how is not yet clear.

  • Filaments and their networks. This is a broad area, inspired by biological filaments (e.g. amyloid fibrils, actin, or microtubules - but equally carbon nanotubes), which uses our expertise in polymer physics. Here the work is mostly theoretical, in collaboration with single-molecule and cell-mechanics experiments in the BSS group. What is the kinetics of filament growth? How is the buckling compression force depends on filament structure? How to understand the ratchet nature of cell deformation from the underlying actin growth/buckling dynamics? These are some of the questions we were working on recently.

  • Carbon Nanotube composites is a big area, where our key contribution lies in (a) quantifying the ways of dispersing the tubes in a viscoelastic matrix and monitoring the degree of dispersion, and (b) thermal and photo-actuation in these composites. The latter is definitely a highlight of our lab: a significant, reversible stress or strain actuation (mechanical response to heating or irradiation) has many exciting applications.

  • Chirality and Biopolymers is an old area of our interest. Again, combining the theory and experiment (dynamic-mechanical and optical), we are trying to establish the effects of molecular chirality and stereo-specific interactions (on the level of primary/secondary structure) on the macroscopic response of polymers and their networks or aggregates structures.

  • Liquid crystalline elastomers are crosslinked or thermoplastic rubbery networks of polymer chains that possess a spontaneous orientational order. The resulting effects are quite unique: from the thermal and photo-actuation (artificial muscles), to the soft elasticity, to the quenched random disorder and complicated dynamics - the liquid crystal elastomers have a real claim to be regarded as a new state of matter!... Our group has a long history of theoretical and experimental studies in this field and also a unique combination of capacities: the chemical synthesis facility, the advanced dynamic-mechanical and optical experimental base and, most importantly, the full synergy between theory, physical experiment and the chemistry.

  • Liquid crystalline colloids have been put on the map in the last 20 years. Symmetry breaking in a liquid crystalline material leads to unusual structures and interaction forces when they become a part of inhomogeneous colloidal system. The arrested dynamics of such systems, effects of topological defects, the possibility to manipulate physical properties - are very important questions with a large practical application potential.

  • My other interests in physics of polymers and liquid crystals mainly lie in topological defects, kinetic theory, fluid dynamics of l.c. colloids or filled l.c. polymers, as well as various issues of phase ordering, interactions, kinetics of mixtures and emulsions with a symmetry-broken component. Experimentally, we are studying the rheology of complex fluid systems, in particular, the response during phase transformations when new structures and internal constraints emerge in the system.

    Several possible PhD projects are available, in all of the above research areas and in all three directions (theory, experiment and chemical synthesis), for the start in October (check the Cavendish rules for PhD application, but contact me first for preliminary discussions). Remember, the official deadline for PhD placements is in March, and it can only be bent in a limited way.
