Tandy Warnow Founder Professor of Engineering Professor of the Departments of Computer Science and Bioengineering Institute for Genomic Biology, Biocomplexity Theme National Center for Supercomputing Applications Affiliate in the departments of Electrical and Computer Engineering, Mathematics, Statistics, Animal Biology, Entomology, and Plant Biology PhD (Mathematics) University of California at Berkeley, 1991 B.S. (Mathematics) University of California at Berkeley, 1984 Current NSF Funding: My research in currently funded by three grants from the National Science Foundation. Multiple sequence alignment, funded by NSF grant ABI-1458652, beginning August 2015. This project will develop new methods for multiple sequence alignment, building on our SATé, PASTA, and UPP methods. Metagenomics, funded by NSF grant III:AF:1513629. This is a collaborative grant with the University of Maryland, for new methods for metagenomic dataset analysis, building on our TIPP method for taxon identification of reads in a metagenomic sample. Graph-Theoretic Algorithms to Improve Phylogenomic Analyses, funded by NSF grant CCF-1535977. I am the overall PI, and this project is collaborative with Satish Rao (UC Berkeley PI) and Chandra Chekuri (UIUC). We are developing new theoretical computer science and discrete algorithms for improving the estimation of large species and gene trees, and specifically enabling statistical methods to scale to ultra-large datasets. Recent NSF funding has supported work in phylogenomics, described here. This is still an area of very active research in my group. I also recently benefited from support of the John P. Simon Guggenheim Foundation, and earlier support from the David and Lucile Packard Foundation, the Radcliffe Institute for Advanced Study at Harvard University, the Program for Evolutionary Dynamics at Harvard University, and Microsoft Research, New England. The Founder Professorship is funded through the Grainger Engineering Breakthroughs Initiative, which is supporting development of research in Big Data and Bioengineering at UIUC. I am grateful to the National Science Foundation for its continuous support since 1994. See this page for completed projects funded by NSF, starting in 2001. http://tandy.cs.illinois.edu
