About

David W. Johnston is a researcher whose work sits at the intersection of marine conservation technology and wildlife ecology. His innovative contributions have advanced the use of robotic and autonomous systems to address pressing environmental challenges, particularly in the realm of sea turtle conservation. Johnston's 2018 study, "Robotic Vehicles Enable High-Resolution Light Pollution Sampling of Sea Turtle Nesting Beaches," exemplifies his forward-thinking approach, deploying cutting-edge unmanned vehicles to precisely quantify the impact of artificial light on nesting behavior — work that has garnered 10 citations and opened new methodological pathways for coastal wildlife monitoring. His research illuminates how light pollution drives sea turtles away from suitable nesting habitats, causing premature retreats to sea and ultimately threatening reproductive success. By combining robotics with ecological fieldwork, Johnston has helped bridge the gap between emerging technology and applied conservation science, offering wildlife managers more accurate, scalable tools for assessing human impacts on vulnerable species. His work represents a compelling model for how technological innovation can directly inform and strengthen efforts to protect marine wildlife in an increasingly illuminated world.
