This workshop, sponsored by AIM and the NSF, will be devoted to the study of how the geometry of "tree space," the space of all rooted trees, can be applied to the solution of problems in biology. A particular focus will be understanding evolutionary relationships, such as reconstructing phylogenetic trees from DNA data. Factors such as conflicts in the original DNA data lead to uncertainty as to the ``true" evolutionary tree; thus a major issue is how to build the tree which best reflects the available data. One possible approach is to cast the problem in terms of finding the center of a collection of points in tree space.
This workshop will bring together researchers in combinatorics, topology, statistics, and biology. We hope especially to facilitate communication between the four groups so that biologists can become aware of the mathematical tools which are available, mathematicians can become aware of the problems which are of interest to biologists, and all four groups can profit from a better understanding of the relationship between statistical and geometric methods.
