I'm a regular contributor to the software RevBayes, where I've worked on ancestral state reconstruction functionality, developed continuous-time Markov chain models of discrete character evolution, in particular chromosome number evolution, and implemented coalescent models to estimate ancient introgression/hybridization events over a phylogeny.
8/2016: SUMAC version 2.0 is significantly faster than previous versions due to the use of a new clustering algorithm.
Supermatrix Constructor (SUMAC) is a tool to data-mine GenBank, construct phylogenetic supermatrices, and assess the decisiveness of a matrix given the pattern of missing sequence data. SUMAC calculates a novel metric, Missing Sequence Decisiveness Scores (MSDS), which measure how much each individual missing sequence contributes to the decisiveness of the matrix. MSDS can be used to compare supermatrices and prioritize the acquisition of new sequence data.
SUMAC constructs supermatrices either through an exploratory clustering of all GenBank sequences within a taxonomic group, or by using guide sequences to build homologous clusters in a more targeted manner. SUMAC will assemble supermatrices for any taxonomic group recognized in GenBank, and is optimized to run on multicore processors by utilizing multiple parallel processes. SUMAC is implemented as a Python package that can run as a stand-alone command line program, or its modules and objects can be incorporated within other programs.
Floristic Quality Assessments (FQAs) are metrics of ecological quality developed by Swink and Wilhelm in 1994. FQAs are calculated using coefficients of conservatism assigned to individual plant species based on their endemism to a certain habitat and tolerance to disturbance.
Widely used by state and federal agencies as well as conservation non-profits to monitor and assess natural areas, FQA databases have been developed for much of the United States. However, all previous FQA computer programs only calculated FQA for a single region or habitat, and for many regions FQA must be calculated by hand. This web-based FQA calculator enables the user to choose from any existing FQA database, and as new FQA databases are developed they can be uploaded into the site. Users can also compare coefficients across databases. The site has a responsive user interface that can be used in the field on mobile devices. This project was developed with support from Openlands.

Restoration Map is an open-source and free web-based application to help plan, implement, and assess ecological restoration projects within Chicago Wilderness natural areas. It is designed to encourage collaboration and improve communication among stakeholders including the landowner agencies, volunteers, restoration contractors, interns, and partner conservation organizations.
The map's users have entered over 1800 map layers representing 13 years of management work and experimentation in Chicago-area restoration projects. By integrating long term monitoring data from the Bird Conservation Network (eBird), the Calling Frog Survey, and other sources, Restoration Map provides feedback on the effects of restoration work, therefore utilizing an adaptive management approach.
Restoration Map has been developed with the support of the National Audubon Society using all free and open-source software. The concept was inspired by Stephen Packard's stewardship of the beautiful Somme Prairie Grove. The map is built on PHP and MySQL, and uses the Google Earth plugin.
