Biography
With training in Aquatic Biology and Oceanography, I am a broadly trained Environmental Scientist who views environmental and societal problems from an earth system science perspective. I work at the interface between sciences unraveling climate mysteries, exploring the relationship between sedimentary strata, helping to improve water quality using electromagnetic sensing techniques, and exploring renewable energy and sustainability solutions to address anthropogenic climate change.
I make use of research methods that span disciplines. I study sedimentary records to extract climate-related information on seasonal to glacial-interglacial time scales. I employ diverse methods ranging from marine micropaleontology to light isotope geochemistry and core and well logging to decipher Earth's climate record. I make use of environmental remote sensing to study harmful algal blooms and agricultural remote sensing methods to monitor soil carbon content and evaluate the impacts of various farming practices.
