Polar climate scientist - exploring the causes and consequences of sea ice change using observations and models.

I am an Associate Research Scientist at NASA’s Goddard Space Flight Center (GSFC) Cryospheric Sciences Lab and the University of Maryland; specializing in polar sea ice variability. I am jointly funded through NASA's Operation IceBridge and ICESat-2 projects. Please explore this website to find out more about my research interests and experiences. Below are a list of current projects I'm actively involved in with colleagues at the GSFC Cryospheric Sciences Lab.

NASA's ICESat-2 : A member of the ICESat-2 Project Science Office (PSO) and Co-I on a newly funded Science Team proposal (PI Tilling) I'm working to better understand the data from this new satellite laser altimeter and provide state-of-the-art estimates of the sea ice state (freeboard, thickness, roughness, floe size).

NASA's Operation IceBridge : A member of the Operation IceBridge Project Science Office (PSO) I'm working to provide novel sea ice data products/analysis and support efforts to produce a long-term sea ice thickness product.

PolarMERRA : Part of a new initative to help produce a new, polar-focussed, atmospheric reanalysis with colleagues in the Cryospheric Sciences Lab and the Global Modeling and Assimilation Office (GMAO).

PRSISE : Leading efforts to launch a new NASA-supported Polar Sea Ice State Estimate (PRSISE) by assimilating remotely sensed data into the CICE sea ice model.
