Dr Jinglang Feng is Chancellor’s Fellow at the department of Mechanical and Aerospace Engineering of the University of Strathclyde. Before joining Strathclyde, she pursued her Ph.D. in Aerospace Engineering of the Delft University of Technology, with research efforts on innovatively modeling, solving dynamics and control problems in the highly nonlinear system with specification on contact binary asteroid systems. Afterward, she continued research as a postdoctoral researcher in Astronomy and Space Science of Nanjing University and Purple Moutain Observatory, where she started to investigate the effect of model uncertainties (e.g. gravity field, solar radiation pressure) on orbital propagation around asteroid and to model the influence of sublimations on the rotation status of a comet, respectively.
Currently, she is continuing the research about orbital dynamics and uncertainty analysis around small solar system bodies. Meanwhile, she is extending her fields to space debris removal and asteroid deflection, where similar methodologies can be shared with for addressing the new challenges. Promising disposal and deflection strategies are expected.
