Faculty Steve Railsback, Matt Johnson Mathematics

Drs. Steve Railsback (Mathematics) and Matt Johnson (Wildlife) collaborated on a paper recently accepted for publication in the “Proceedings of the National Academy of Sciences.” The paper presents a mathematical model on the controversial trade-off between allocating land for crop production versus conservation of biodiversity. Their model shows that, for coffee farmers, growing trees to attract birds not only benefits biodiversity, it also boosts net crop production because birds help control insect pests. The paper will be published next week.

The Math Department had twelve students in four teams compete in the International Mathematical Contest in Modeling this January. Teams are challenged to analyze an open applied problem and to propose a solution using mathematical modeling over an intense four-day competition. All four of our teams were recognized by the judges as either Honorable Mention or Successful Participant for their papers.

The students were advised by Dr. Kamila Larripa (Math) and are listed below.
