My primary research interest concerns the understanding and analysis of complex network systems and quantum systems in which linear algebra is used as an indispensable tool. Mathematically, I research on theory and numerical algorithms for problems involving structured matrices.
Many real world systems can be viewed as systems of interconnected systems. In the language of mathematics, these systems can be considered as networks in which the nodes represent individual systems and dependencies between them can be interpreted as links which are sometimes known but dynamic or not known. This half-known behavior of dependencies contributes to complexities in understanding the behavior of the entire system. Since networks can be represented by certain structured matrices, the properties of these matrices become increasingly important for the analysis of the network systems. Thus theory and numerical algorithms for structured matrices play a significant role in solving problems arise in network systems.
In multipartite quantum systems, it is believed that the phenomena of entanglement has no classical analogue and the detection of entanglement remained an open problem for high-dimensional systems. Since quantum states are represented by density matrices (sometimes represented by a network), mathematically, it necessitates the development of new techniques for dealing with structured matrices.
