With training in Aquatic Biology and Oceanography, I work at the interface between sciences unraveling climate mysteries, exploring the relationship between sedimentary strata, and helping to improve water quality using electromagnetic sensing techniques.
My primary research interest is in the area of paleoclimate. 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.
