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.
With David Weitz we have put together a volume: The Oxford Handbook of Soft Condensed Matter (here, I am afraid, the OUP didn't let us upload a PDF).
I am involved in a number of research 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:
Molecular motors and sensors. This is the 'biophysics proper'. We did some work, and are still active in the theory of the ATP-fuelled rotary molecular motor (like F1 ATPase); this is in contrast to the pmf-driven rotary motors (like F0 ATPase or flagellar motor). Mechanosensing of the 2nd kind, that is, generating a response to the stiffness of cell environment (as opposed to the '1st kind' responding directly to applied force/pressure) is a very active area of our research, both in theory and experiment. Understanding the sensor and the subsequent signaling pathways is a direct route to model cell morphology and the transition to active motion, which is the longer-term aim here...
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. The big ERC grant supports this research.
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. Recent experimental projects examined how fascia and other ligamentous tissue respond 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 the kind of questions we were working on recently.
Chirality and Biopolymers is an old area of my 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.
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 at any given time, 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
but contact me first for preliminary discussions). Remember, the PhD applications need to be submitted no later than December-January (or earlier, if funding is not clear).
