Dr. Johnston’s research focuses on the incursion patterns of invasive species, such as the lionfish.  Using complex agent-based computer modeling, these models couple biological traits of the invader, such as their breeding strategy and habitat preferences, with physical characteristics of the environment to produce invasion forecasts.  This work has advanced the present knowledge of marine invasions and has also provided ocean managers with strategies on where and how much effort is needed to control invasive marine fish.  Continued work focuses on understanding the biophysical interactions that drive marine and terrestrial invasions on a global scale.
