    Prof Kristian Muller-Nedebock (SU)

    Good morning All,

    The National Institute for Theoretical Physics, and the Centre for Theoretical Physics, School of Physics, would like to invite to its coming talk in the theoretical physics seminar series, entitled:

    "Statistical physics of cytoskeletal filaments that are pushed by molecular motors"

    to be presented by Prof. Kristian Muller-Nedebock (Stellenbosch University)

    Abstract: A variety of molecular machines (dyneins, kinesins and myosins) operate on filaments such as F-actin or microtubules, which are constituents of the cytoskeletal structures within cells. Together with processes that cause the filaments to grow or shrink and to form networks, the activity of the molecular motors leads to complex and rich dynamical behaviour. Structural randomness and the thermal environment of the cell make statistical physics a necessary modelling tool to explore the mechanical properties of such systems. An introduction to a selection of the physical properties of molecular motors, filaments and networks will be given. In particular we wish to hone in on the issue of contractility of active gels and also of contractile rings (as during cell division). Along the way we shall encounter motility assays, the formation of networks, and try to motivate why some of the physics in these systems can be mathematically challenging.

    Dates: Tuesday, 14th October 2014
    Venue: Frank Nabarro Lecture Theatre P216
    Time: 13.20 - 14.10

    I hope you shall all be able to attend,

    Yours sincerely,
