I was Born and raised in New Orleans, Louisiana, where I also attended the University of New Orleans and received my Bachelor of Science and Master of Science degrees in Biology. I am currently employed by Tulane University as the Manager of Informatics for the Tulane University Biodiversity Research Institute. My current research interests focus on the design and development of technologies that enhance utilization of natural history data with a focus on ichthyological collections.

Active Projects:

This project is working to generate monthly streamflow and water temperature predictions for stream sections in all major watersheds across the United States and Canada from 1950-2099. The HydroClim data portal is being designed to support temporal and spatial browsing, querying and downloading projected flow volumes and water temperatures. Furthermore, the data are being integrated with the FishNet2 data portal, facilitating characterization of habitat requirements for freshwater fishes in the United States and Canada. I serve as the Co-PI and lead developer of the Hydroclim Data Portal and FishNet2 integration. Hydroclim is a collaboration between Tulane University, Saint Louis University and Indiana University.

The goal of this project is to design and develop hardware and software for high-throughput multi-view imaging of natural history specimens suitable for photogrammetric 3D-reconstruction.

FishNet 2
FishNet is a collaborative effort among fish collections around the world to share and distribute data on specimen holdings. Released in July of 2010, FishNet 2, is the successor to the original FishNet network. I serve as the Co-PI and lead developer of FishNet 2 and am working with twelve collaborating institutions to expand and improve upon data quality within the FishNet network with a primary focus on geospatial referencing of records lacking geographic coordinates.

The GEOLocate project began in February of 2002 as an effort to develop efficient computer-assisted methods for georeferencing natural history collections' data. GEOLocate now comprises a collection of interoperable software components that facilitate the retrospective georeferencing of legacy specimen occurrence data from anywhere in the world. I serve as Co-PI and lead developer.

GEOLocate CoGe
The goal of this project was to design a collaborative georeferencing framework around the GEOLocate georeferencing platform. This project supports the needs of large scale georeferencing by allowing users to create communities that share datasets and distribute workload. Similarity matching between shared records further increases the efficiency of georeferencing. A web-based data portal is used for creation and management of georeferencing communities. Verification of data within a community is accomplished through a specialized GEOLocate web client. I serve as Co-PI and lead developer.

Past Projects:

VertNet aims to bring together data from FishNet, MANIS, HerpNet & ORNIS within a unified cloud based architecture. I served as a Co-PI and was involved in the integration of georeferencing services with VertNet's cloud architecture, maintaining HerpNet 2 and ORNIS 2 as transitional networks and outreach through Biodiversity Informatics Training Workshops.

HerpNet 2 & ORNIS 2
HerpNet 2, which ran from March of 2011 through January of 2015, and ORNIS 2, which ran from June of 2012 through January of 2015 were networks based upon infrastructure developed for FishNet 2, but for herpetological and ornithological data respectively.

Taxon Footprint validation of georeferenced localities
Taxonomic footprints are sets of polygons that define areas of species co-occurrence based on previously georeferenced occurrences of species collected at a locality. The footprints can be used in validating coordinates assigned to the locality by automated georeferencing tools. We developed web services that query species point occurrence data from the Global Biodiversity Information Facility given a list of species, buffers those results and produces a composite overlay representing areas of co-occurrence. These results can then be used to validate the results of automated georeferencing.

Cypriniformes Tree of Life Data Management Portal
This project involved the design and implementation of a combined data management platform for genomic data, museum holdings & morphological data. The CToL Portal was one of the early pioneer projects using standardized vocabularies (ontologies) to define morphological characters and states.

Louisiana Fish and Wildlife Conservation Network
The Louisiana Fish and Wildlife Conservation Network (LFWCN) was a prototype information system focused on the conservation of Louisiana's inland fishes. The LFWCN harvests data using the DiGIR protocol and provides a web portal for the textual and spatial query of specimen occurrences. As data are harvested, UBio services are utilized to provide name resolution. Names which cannot be resolved by UBio are manually verified. The LFWCN was used to produce assessments for all threatened and endangered fishes within Louisiana. Technology from this project was leveraged in building FishNet 2.

Biogeomancer Collaboration
Biogeomancer was an alternative georeferencing application. My role involved developing web services for interoperability with GEOLocate and contributing to development of georeferencing standards.
