I am invested in furthering our knowledge on ecosystem response to natural and manmade disturbances — with a focus on invasive species and global change — to guide natural resource management and environmental policy design. One of my trademarks is using photography and other imagery to collect and communicate scientific information.
Effectiveness of ballast water management regulations at reducing invasive species risks (national)
USCG Type Approval of ballast water treatment technologies (national)
Stress resistance and transfer of nonnative species on ship hulls (global)
In situ removal techniques for Didemnum vexillum (Alaska)
Conservation planning to prevent spread of introduced marine species (Bermuda)
