Biography:

I am a research scientist at the Max Planck Institute for Demographic Research (MPIDR) working on a wide range of computational social science problems including algorithms and mathematical models for analyzing networks and international mobility of researchers. My background is in Network Science and Operations Research and I have an Erdős number of 3.

I have worked in the intersection of network science and mathematical modeling to develop efficient computational models and algorithms for analyzing the structure of large-scale networks. In particular, I focused on the fundamental mathematics of formulating graph optimization models to analyze networks with positive and negative edges (a 6-minute presentation).
