 Abstract: Coastal cities are increasingly shaped by human activity, yet ma
 ny of the impacts occur below the waterline. My research has focused on un
 derstanding how urban stressors such as artificial structures, stormwater,
  and industrial pollution impact on marine ecosystems, and how we can desi
 gn solutions to mitigate these impacts. Artificial structures like seawall
 s, pilings and pontoons tend to create featureless surfaces that lack the 
 complexity of natural habitats, reduce biodiversity, and create a niche fo
 r invasive species. Through the Living Seawalls project in Australia, Iā€™
 ve worked with collaborators to develop and test eco-engineered panels tha
 t add habitat complexity and support native species. These panels have now
  been installed in more than 10 countries around the world and are providi
 ng insight into how different geometries perform under different environme
 ntal conditions. Through this project I have also explored how ecological 
 principles can inform port design to reduce the risk of marine invasions, 
 using biosecurity research to guide infrastructure planning. Other stresso
 rs associated with coastal cities include the contaminants introduced by s
 tormwater. My work on the structural and functional impacts of contaminant
 s has included measuring the responses of macro- and micro-organisms to st
 ormwater. In collaboration with the City of Sydney, Iā€™ve also investigat
 ed whether sediment-dwelling organisms (bioturbators) can help remediate s
 tormwater-contaminated sediments by enhancing microbial processes. Industr
 ial pollution is another persistent stressor, and Iā€™ve been using enviro
 nmental DNA (eDNA) to detect changes in benthic communities and assess eco
 system health. In my talk Iā€™ll also introduce the work of the Stone Livi
 ng Lab in Boston, where we are applying nature-based approaches to build c
 oastal resilience with the support of different government, community and 
 industry stakeholders. Together, these projects aim to inform sustainable 
 design and management of urban coastal environments. Join Meeting https://
