I am responsible for maintenance of custom software packages currently in use by researchers and staff at the OC including CPCe (Coral Point Count with Excel Extensions). I also develop and maintain several websites including the shark tracking web portal for the Guy Harvey Research Institute (http://www.nova.edu/ocean/ghri/tracking/) and the Global Invertebrate Genomics Alliance (http://giga.nova.edu/) website .
Area(s) of Research
I am particularly interested in invasive species and their patterns of invasion in their introduced environments. I have developed and am currently enhancing a predictive model based on the lionfish invasion in the western Atlantic and Caribbean region.
