NSF grant funds study of evolutionary game theory |
| By David Dodson |

| UGA economics professor Don Keenan
and Pejman Rohani, an assistant professor with UGA’s Institute
of Ecology, have been awarded a $100,000 research grant from the National
Science Foundation for their proposal, “On Long-Term Consequences
of Selfish Behavior: A Game Theoretic Approach to Host-Pathogen Co-Evolution.”
The cross-campus partnership was aided by Matt Bonds, who completed his Ph.D. in economics from UGA’s Terry College of Business last year and is now pursuing an additional graduate degree in ecology. “The collaboration began because of Matt finishing up his Ph.D. in economics and beginning one in ecology, which this project will presumably constitute,” says Keenan. NSF’s funding of the proposal kicks in this year and lasts for two academic years. “The grants are quite competitive and rather prestigious, so I am very pleased that we received it,” Keenan also says. In fact, the NSF receives about 40,000 competitive requests for funding each year. In the category for which Keenan and Rohani applied, only about 5 percent of the applications are awarded funding. Keenan has a research background in the area of game theory, which he says was originally developed to study the conscious interaction of “rational” agents. “For instance, it would be the preferred economic method for studying how two firms might compete with one another in the marketplace,” he says. “There is, however, a newer branch, called evolutionary game theory, which is useful in biology.” “Our work will apply game theory to the conflict between that most rational of creatures—humans—and the viruses causing human disease, such as AIDS. While not outwardly rational, viruses mutate and reproduce with alarming speed,” he says. “By using an explicitly game theoretic framework, we can simultaneously capture how humans respond to the virility of a disease, and how viruses respond to treating a disease.” “We are then in a position to design better responses to viral diseases, applying the full knowledge of what their ‘rational’ reaction is likely to be,” says Keenan. He adds, as a final note, that the solution technique being applied is the Nash equilibrium, the creation of Nobel laureate John Nash, who was depicted in the film A Beautiful Mind. |
