My research focuses on collective phenomena in interacting systems, including voting, information cascades, and financial markets.
A central theme is the emergence of correlation, scale invariance, and phase transitions across different domains.
I study how collective behavior emerges from interacting agents, across systems such as voting, markets, and optimization processes.
I began my research in statistical physics and lattice systems, with a particular interest in disorder, entropy, and structural transitions in interacting systems.
Another major direction of my research concerns voting models, ranking dynamics, and scale-invariant structures emerging from collective choice.
I have also studied information cascades, social learning, and phase transitions in collective decision-making processes, using both stochastic modeling and experimental approaches.
In the field of econophysics and quantitative finance, I have worked on correlated default models and credit risk, with a focus on correlation structures and implied default distributions.
More recently, I have been interested in optimization dynamics inspired by statistical mechanics, including ant colony optimization and related phase-transition phenomena.
These papers represent the main directions of my research.
