Early on, a fascination with economic models and decision-making led to research on behavioral economics.  Masters research was conducted among fisherman along the Lake Volta, near the village of Keta Krachi, documenting how cultural norms drove cooperative behavior that conserved open pool resources - behavior that rational choice theory could not predict.  



Doctoral research turned to exploring the evolutionary qualities of cultural systems.  In Mauritius, work documented the flow of culture, and lack thereof, across ethnic group boundaries in the presence of significant inter-ethnic marriage.  Unlike the flow of genes across the same boundaries, the linkage of one cultural attribute to another resulted in ethnically defined cultural constellations of traits to remain intact.  The result of these an other dynamics were robust and evergreen ethnic group boundaries that would not diminish over time.
