My research interest is in complex systems, particularly in understanding the emergence of structures as a result of interactions between the constituent units of complex systems at different levels and scales of organisation. Through my investigations, i try to gain insight into the structural aspects of these systems by means of formal modelling of the interactions and representing them as complex networks, primarily using graph theory and algebraic topology as frameworks for modelling.
