Kristina Wärmefjord is professor in Product and Production Development at Chalmers University of Technology. She took her PhD 2011 and works within the research group of “Geometry Assurance & Robust Design”. Her main research focus is on variation simulation for non-rigid parts and methods to decrease the gap between simulated values and the real outcomes, i.e. increase the accuracy of non-rigid variation simulations. With increased accuracy, quality can be improved, simulations can replace physical prototypes and costs can be reduced.
