I am a biological oceanographer at NASA Goddard and a member of the Field Support Group (FSG), part of the Ocean Ecology Laboratory (OEL; Code 616). The FSG collects in situ optical and biogeochemical data for Earth science climate data records and other supporting data records used for ocean color satellite vicarious calibration, data product validation, and bio-optical algorithm development. To this end, the field support group participates in large scale field campaigns, where in situ instruments are deployed to measure the optical properties of the ocean water column as well as collect biogeochemical samples. I have vast experience participating in global oceanographic field campaigns, traveling to such areas as the Chukchi Sea, the Southern Ocean and North Atlantic. My expertise is in IOP measurments and analysis. My interests also include phytoplankton ecology and diversity throughout the global ocean and the detection of phytoplankton types using satellite ocean color data. I am also a PhD candidate at the University of Marland, College Park where my dissertation is focused upon phytoplankton ecology and optical water types in the Chukchi Sea.
Collect, measure and analyze optical and phytoplankton taxonomy samples collected during aquatic field campaigns.
Development and validation of phytoplankton group models and algorothims
Understanding the changes of SST and sea ice extent on the optics and ecosystem of the Chukchi Sea.

In situ optical and biogeochemical in- and above-water measurements are critical for calibration and validation of satellite ocean color radiometry data products, and for
refinement of ocean color algorithms. During the SeaWiFS era, NASA commissioned the development of a series of ocean optical measurement protocols, which have served
as international reference standards ever since, and have promoted the collection and assembly of climate quality, ocean optical datasets by the global ocean color
community. Over the past few years, NASA has sponsored several international workshops (sometimes in conjunction with IOCCG) with subject matter experts to update and
develop new community consensus field measurement protocols for ocean color sensor validation. Newly-drafted protocols are available to the international user
community on the IOCCG webpage for a period of time for public comment and access and associate editorial board peer-review, before they are accepted as international
reference standards. Finalized protocols receive a version number and digital object identifier from IODE Ocean Best Practices. The updated protocols are intended to be
“living” documents, periodically updated as methods and technologies advance.
