Our lab is focused on understanding how and why earth’s climate varied in the past with the hope that such information will help mitigate the effects of ongoing change. We also explore how marine organisms are responding to human impacts like ocean acidification. Tools of our trade include traditional and novel techniques, often involving isotopes, which we apply to carbonates from marine and terrestrial environments. The world is our laboratory and our field sites extend from far off tropical oceans to the mountains and seas in our Pacific Northwest backyard.

I acknowledge that I live and work on the ancestral homelands of the Coast Salish Peoples, who have lived in the Salish Sea basin, throughout the San Juan Islands and the North Cascades watershed, from time immemorial. I express my respect and gratitude for our Indigenous neighbors, the Lummi Nation and Nooksack Tribe, for their enduring care and protection of our shared lands and waterways.
