Short CV
Christina Esch is a Ph.D. student at the Theoretical Geodesy group since 2014. As student she worked as an assistant for the VLBI group and finished her Master thesis on “VLBI analysis using an Inequality Constrained Least Squares Method” in 2014. She is currently working on Differential Radar Interferometry (D-InSAR) analysis. In her research she focuses on the L1-norm phase unwrapping problem in a sparse multidimensional grid of points and in this context on efficient (mixed-) integer linear programming solver and primal/dual conversions.
