Social influence maximization
Social influence can lead to changes in behavior, choices, and beliefs. Understanding the mechanisms of influence spread is important in effectively targetting interventions, such as public health messages, and designing incentives to aid the spread of desirable actions, such as ethical behavior in a company.
My main contribution has been in delineating the effects of information availability and timing on optimal influence policies.
In this line of work, I have examined optimal seeding strategies under partial network visibility, optimal budget allocation across time for an electoral campaign (including the development of a new centrality measure), the effect of incentives and whistleblowing policies on ethical behavior within a company, and the effect of social comparison and group norms on social group stability.
This highly inter-disciplinary area has led to some of my most fruitful collaborations, and I am excited to see what further insights control theory and optimization can bring to social systems in general.
