  • Brief Bio

    Dr. Andrea Andrew is originally from the beautiful island of St. Lucia in the Caribbean, where she started her career as a high school science and mathematics teacher. She came to the United States in 2004 to pursue her studies in Chemistry particularly with its application to the environment. In 2007, Dr Andrew graduated Magna Cum Lauder from the City University of New York, Brooklyn College with a BSc. in Chemistry. Dr. Andrew went on to receive her Masters and PhD in chemistry from the University of Maryland in 2011 and 2014, respectively. During her time at the University of Maryland, Dr. Andrew taught several chemistry courses including an upper level analytical chemistry course for several semesters. Upon successful completion of her studies at the University of Maryland, Dr. Andrew joined the Ocean Ecology Laboratory at NASA Goddard Space Flight Center in January 2015, as a Visiting Scientist 1, and transitioned to a Scientist 1 position in December 2017.

    Research Interests

    Research Interests

    Before joining the Ocean Ecology lab at NASA Goddard Space Flight Center, Dr Andrew's research was focused on examining the distribution and dynamics of the optical properties of dissolved organic matter (DOM) in oceanic and terrestrial waters. She also investigated the possible origin of their unique optical properties through chemical reduction of DOM.  Dr. Andrew also particiaptes in field campaigns for collection of water samples and field radiometry.

    Current Projects

    Current project

    Dr Andrew's current research involves developing an experimental protocol to determine the quantum photoproduction efficiency of dissolved inorganic carbon via photodegradation of CDOM in a mangrove coastal environment. This involves photodegradation experiments using a solar simulator, followed by quantification of CO2 produced using a Coulometer. Dr Andrew plans to eventually use the photoproduction efficiencies in conjunction with airborne and satellite ocean color data, radiative transfer modeling and ancillary data to estimate the long term photoproduction rates in the mangrove coastal environment.
