Logan's research focuses on the environmental impacts of war and military operations in the scope of the US-led Global War on Terror in the US and internationally. Logan addresses military toxins in their persistent effects on land, body, and culture. Overarching themes in Logan's writings include how to frame accountability, how to press the issue in public discourse, and how citizen-scientists can rigorously study military toxins as laypeople guided by professional scientists. Logan serves impacted communities in Hawai'i and Iraq. Logan co-leads a citizen-science initiative investing depleted uranium from US Army use on Hawai'i Island.
