WRITING & SPEAKING

On snails, I have written about social networks and the making of ecological knowledge about tree-snails, and the kinds of possible ethics of engagement generated by molluscan species introduction and extinction in the Hawaiian Islands. 

I have also written about a deep-sea mining museum in rural Czechia, on the links between 19th century abyssal sediments and mid-20th century economic geology, and on approaches to the study of manganese nodules as hybrid biogeological objects in large American research programming during the 1970s and this history’s consequences for multispecies approaches to the history of deep-ocean environments. Forthcoming writing covers subjects related to deep-sea mining and ocean governance in Norway and Singapore, deep seawater’s Hawaiian history, and configurations of conservation practice in Sulawesi’s ancient lakes.  

I speak and organize panel sessions regularly on the history of oceanic environments and resource extraction, and on the contexts of invertebrate species conservation. I am also available to write book reviews, op-eds, and to consult on related concerns.
