This is the home page of the Stoltzfus research group at IBBR (Institute for Bioscience and Biotechnology Research), a partnership of UMD, UMB and NIST.  

We rely on computer-based approaches to address challenges in the areas of molecular evolution, evolutionary theory, and bioinformatics.  Some currently active projects include: 

• New methods for calibrating phylogenetic trees using fossil data (Ryan Norris)
• The evolution of ORFans in E. coli (Guoqin Yu)
• The significance of origin-fixation models in evolutionary genetics (with David McCandless of Duke U)
• Improving interoperability of software and data resources  in evolutionary research (see the HIP working group for more details)
