The symposium (funded by the Smithsonian Institution) will take place on Sunday, May 20, and will feature talks on new methods for multiple sequence alignment and phylogeny estimation by Michael Braun (Smithsonian Institution, USA), Kazutaka Katoh (AIST, Japan), Jim Leebens-Mack (Univ Georgia), Ari Loytynoja (Helsinki, Finland), Ben Redelings (Duke, USA), Daron Standley (Osaka, Japan), Tandy Warnow (Texas, USA), and Derrick Zwickl (Univ Arizona). The symposium will be followed by two one-day workshops, which will be funded by the National Science Foundation through NSF grant DEB 0733029 for Large-Scale Simultaneous Multiple Alignment and Phylogeny Estimation. Registration is required for both the symposium and the workshops, and attendance is limited due to space constraints. The workshop will provide training in new methods for multiple sequence alignment and phylogeny estimation, including personal assistance in analyzing datasets using the SATé software (see this page). To apply for the workshop, please download the application here. For more information, please send an email to Tandy Warnow. See this PDF for information on hotels and local travel within DC. To register for the Symposium, please contact Sarah Kingston at "kingstons 'at' si.edu".
This session is co-organized by Noah Rosenberg (Stanford), Luay Nakhleh (Rice), and Tandy Warnow (UT-Austin), reflecting the research activity in our joint NSF grant (DBI-1062335) on Novel Methodologies for Genome-scale Analysis of Multi-locus Data.
Office hours Spring 2012: Tuesdays (starting Jan 24) 3:00-5, or by appointment.
My research focuses on the development of mathematical models and algorithms for estimating evolutionary history in Biology and Historical Linguistics. The main objective is to develop methods that produce much more accurate estimations of evolutionary history than can be obtained using existing tools. Our group is distinguished from many other groups in computational biology due to our focus on ultra-large datasets, with up to 500,000 sequences. We use real data and perform simulations to evaluate the performance of methods that we develop. This research area inolves mathematics, probability, statistics, computer science, and intensive collaborations with domain specialists. My current research is funded by the National Science Foundation (DEB 0733029 and DBI-1062335) and by the John P. Simon Guggenheim Foundation.
Software: SATé co-estimates trees and alignments, quickly and accurately. The public distribution is available through Mark Holder's group in Kansas. See this page for more about SATé. The DACTAL software estimates trees without needing to estimate a multiple sequence alignment, and produces trees of comparable accuracy to SATé, but in a fraction of the time. See our paper about DACTAL. SEPP performs phylogenetic placement of short reads into an existing phylogeny, using an estimated alignment; it can also be used to estimate alignments and phylogenies from datasets that contain some fragmentary sequences. We are currently extending SEPP to work on taxon identification of metagenomic reads. See this paper for more about SEPP.
