    Sodium channel defects: Molecular mechanisms underlying myopathies
    Professor Ruben studies the role of excitable ion channels in the genesis of several important muscle and brain diseases, including cardiac arrhythmias and epilepsies. His research makes use of an interesting model system, toxin-resistant ion channels in garter snakes, to gain insight into the role of proteins in muscle function.
  • Douglas Swank, Department of Biology, Rensselaer Polytechnic Institute, Troy, NY, USA
    Designing Molecular Motors: Myosin Structural Regions that Determine Muscle Mechanical Properties
    Professor Swank's research focuses on understanding the molecular basis for muscle fiber type properties. Using Drosophila, he combines protein engineering, single molecule biophysical assays, muscle mechanics, and locomotion assays for a fully integrative picture of the influence of protein structure on muscle function.
