Liubov Tupikina
Biography
Liubov is researcher with background in mathematics, theoretical physics. She did her Phd in Humboldt University of Berlin, worked in Universities of France, Germany, the Netherlands, Spain, Uruguay.
At Bell labs Liubov is focusing her work on around several topics: robustness of networks, processes on random networks, time-series analysis and embeddings. She is also interested in studying how collective intelligence helps us to build tools for understanding responsible AI. Using stochastic processes and random networks she also works now in survivability processes theory applied in the context of studying time-series processes. She works on development of embeddings applied to various datasets from innovation in science to evolution of data of users.

Characterizing flows by complex network methods
Authors Reik V Donner, Michael Lindner, Liubov Tupikina, Nora Molkenthin Publication date 2019 Book A mathematical modeling approach from nonlinear dynamics to complex systems Pages 197-226 Publisher Springer, Cham Description During the last years, complex network approaches have demonstrated their great potentials as versatile tools for exploring the structural as well as dynamical properties of complex systems from a variety of different fields. Among others, recent successful examples include their application to studying flow systems in both, abstract mathematical and real-world geophysical contexts. In this context, two recent developments are particularly notable: on the one hand, correlation-based functional network approaches allow inferring statistical interrelationships, for example between macroscopic regions of the Earth’s climate system, which are hidden to more classical statistical analysis techniques. On the other hand, Lagrangian flow networks provide a new tool to identify dynamically relevant structures in atmosphere, ocean or, more generally, the phase space of complex systems.
