"I study earthquakes and active faults by combining remote sensing techniques, field observations and mechanical modeling. Spatial variation of fault friction properties is probably a key factor determining the spatial extent, size and timing of earthquake ruptures. A major goal of my research aims therefore at defining the spatial and temporal variability of frictional properties of faults. My project is to use Synthetic Aperture Radar (SAR) images to measure the time evolution of surface deformation around the Longitudinal Valley Fault in Taiwan. Times series of SAR interferograms will be combined with geodetic and seismic data to determine the temporal evolution of slip a depth. This approach will reveal the fault patches which have remained locked, accumulating stress to be released in future earthquakes, those patches which have slipped during earthquakes during the time period covered by the data (a Mw 6.8 earthquake which occurred in 2003 in particular), and those patches which are undergoing aseismic creep. Frictional properties will be determined from comparison of observations with dynamic modeling of fault slip. The results will be analyzed in view of the geological context to identify the factors controlling fault friction (lithology, fluids)."

"My research focuses on the design of locally optimal, fuel-efficient spacecraft trajectories employing the ideas of dynamical systems theory and optimal control. Invariant manifolds, tube-like structures in the planar circular restricted three-body problem along which spacecraft may travel using no additional energy, provide structure for the design of initial guess trajectories that may be optimized using the local optimal control algorithm DMOC (discrete mechanics and optimal control). Combining DMOC with invariant manifolds, it is possible to produce trajectories that travel from the Earth to the Moon using approximately 20% less fuel than a Hohmann transfer. Furthermore, I am working on a time-adaptive version of DMOC that would allow for faster and more accurate optimization of highly nonlinear problems, like those in space mission design. This work is also applicable for the design of transfers between moons in the Jovian and Saturnian systems, e.g. for NASA's future Europa or Titan missions, as well as to periodic orbits around Lagrange points, like NASA's Genesis mission."January 2011

"Receiving the Keck Institute for Space Studies graduate student fellowship allowed me to continue my studies at a graduate level in Aerospace Engineering at Caltech. The Aerospace Engineering Master's program helped solidify my understanding of the fundamentals of aerospace engineering, as well as giving me the opportunity to work and interact with an extremely talented group of students. In addition, after completing the master's program, I was able to participate in the exchange program between GALCIT and École Polytechnique. Spending last year abroad in Paris was an amazing experience, and I am very thankful for the support from the Keck Institute for Space Studies for making these opportunities possible."September 2010
