Faculty & Staff

Matt Johnston

Research Scientist, Scientific Computer Programmer


Primary Responsibilities

I am responsible for maintenance of custom software packages currently in use by researchers and staff at the Halmos College of Natural Sciences and Oceanography 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 and the Global Invertebrate Genomics Alliance 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.
