So, having just built my home machine I wanted to test this (1x Quad 2.83 Ghz) against 1) my work desktop machine with equivalent processors but Xeon (so server chips instead of desktop chips; 2x Quad 3 Ghz) and then I wanted to test against someone’s new Nehalem Xeon server chips (2x Quad 2.66 Ghz [...]
I got a mention in the New York Times today for a large tree that is in press at BMC Evolutionary Biology (to be published today). Crunching the Data for the Tree of Life This is work done when I first started at NESCent with my coauthor’s Michael Donoghue and Jeremy Beaulieu at Yale. We [...]
Some colleagues and I (especially Jeremy Beaulieu and Michael Donoghue) have been interested in making large phylogenies. We have been trying to develop (semi) automated methods and implementations that can assemble datasets quickly. The assembly of the phylogeny and matrix itself appears to not be the major computational problem anymore. Although we are sure to [...]
Just published a paper in Science (October 3, 2008 issue) with Michael Donoghue. It is titled Rates of Molecular Evolution Are Linked to Life History in Flowering Plants . Basically, we found that rates of molecular evolution in 5 large plant phylogenies are linked to generation time (life history). The largest phylogeny was of Commelinidae [...]
