With training in Aquatic Biology and Oceanography, I work at the interface between sciences unraveling climate mysteries, exploring the relationship between sedimentary strata, and improving water quality using electromagnetic sensing techniques.

My primary research interest are in paleoclimate and environmental remote sensing. 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. My environmental remote sensing work adapted the multivariate statistical methods I use for paleoclimate work to study multispectral and hyperspectral remote sensing images of harmful algal blooms in optically complex, coastal and inland water bodies. This enables differentiation of various types of algae from cyanobacteria and suspended sediments using hand-held, aerial or orbital sensors.
