A researcher in biophysics who develops optical tweezers to measure how molecular machines, including kinesin, generate forces. Such experiments connect motion at the scale of individual molecules to the mechanical behavior of cells.[ref]
Professional profile of Erik Schäffer at the University of Tübingen. Research: single-molecule fluorescence and force microscopy, kinesin motors and DNA repair
He coauthored a calibration method combining thermal motion with a known oscillation of the sample stage, allowing the trap to measure forces without assuming the bead size or fluid viscosity.[ref]
Calibration of optical tweezers with positional detection in the back-focal-plane by Simon F. Tolić-Nørrelykke and others. Abstract: thermal-spectrum and driven-stage calibration
