  Research Interests
Chris Cosner, an applied mathematician, is interested in studying mathematical models for the the ways that organisms interact with each other, humans, and the environment, especially in their utilization of space. In the Bahamas Biocomplexity Project, he intends to focus on formulating and analyzing mathematical models for marine protected areas (MPAs). The models will incorporate population dynamics, the possible spatial arrangement of the MPAs, transport of organisms into, out of, and among the MPAs, and the economic benefits and effects on biological populations of fishing. Work includes collaboration with other theoreticians in the Project on developing and using mathematical models that can help compare the different costs and benefits, both ecological and economic, that can be expected to arise from different decisions about where MPAs are located and how they are regulated.
