Welcome to the lab page for Stephen A. Smith's lab at the University of Michigan, Ann Arbor. You can find out more information about the people in the lab here and the projects here. A lot of the research in the lab focuses on plant evolution, detecting and describing large scale patterns of evolution, examining differences in the rate of molecular evolution, and using new data sources like transcriptomes and genomes to address these questions. A great deal of this involves the development of new methods and new computational tools. My faculty page is here.



Lab updates

  • PyPHLAWD published

    Dr. Joe Walker (recent grad from the lab) and I have published our program PyPHLAWD in Methods in Ecology and Evolution. Check it out here! You can check out PyPHLAWD here.

  • Joe Walker defends

    Dr. Joe Walker successfully defended his dissertation today! Joe Walker is the first Smith lab graduate student to finish. And he did it in a cool 4 years with all chapters published or in review. Congrats Joe!! joe

  • PyPHLAWD site up

    PyPHLAWD website has been put up and updated! You can find it here. There are several examples of runs. More updates will follow!

  • A couple new papers: plant tree of life and quartet sampling

    A couple of our papers just came out in the Tree of Life special edition of AJB. Pease et al. Quartet Sampling distinguishes lack of support from conflicting support in the green plant tree of life looks at different ways to examine support in a phylogeny using a bunch of green plant examples. Smith and Brown Constructing a broadly inclusive seed plant phylogeny uses OpenTreeOfLife and GenBank to make a big dated seed plant phylogeny.

  • Postdocs moving on to new positions

    Congrats to Simon and Joseph who are moving on to a research position (Joseph) and a new phylogenetic startup phylagen.com (Simon). It was awesome to have you here at Michigan and good luck!
