Wednesday, September 22, 2004 8:15 - 9:00 Breakfast and Registration - CoRE Bldg., 4th Floor 9:00 - 9:10 Welcome and Opening Remarks Mel Janowitz, DIMACS Associate Director 9:10 - 9:55 Directed Scenarios of Gene Histories over an Evolutionary Tree as Virtual Reticulation Events Boris Mirkin, Birkbeck University of London, UK 10:00 - 10:40 Discussion 1. What needs to be done on the mathematical/CS side for better understanding reticulation? 10:40 - 11:10 Break 11:10 - 11:40 Bayesian Analyses of Hybrid Populations Robbie Young, Monterey Bay Aquarium Research Institute 11:40 - 12:20 Discussion 2. What needs to be done at the biological level to better understand reticulation? 12:20 - 1:30 Lunch 1:30 - 2:10 Discussion 3. How can math/CS and biology most fruitfully collaborate to advance inference and reconstruction of reticulate events? 2:10 - 2:40 Computational Evaluation of Interspecific Gene Transfer between Fully Sequenced Genomes Samuel Handelman, Columbia University 2:45 - 3:25 Discussion 4. How can math/CS and biology most fruitfully collaborate to develop and test models that distinguish among different aspects of reticulation (population vs. species levels, apparent (error induced) vs. real reticulation, etc.)? 3:30 Meeting ends
