Sinéad Farrell photoSinéad Louise Farrell is an Assistant Research Scientist at the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland, College Park, collaborating with the NOAA Laboratory for Satellite Altimetry and the NASA Cryospheric Sciences Branch. Dr. Farrell is affiliated with the Cooperative Institute for Climate and Satellites (CICS), within ESSIC. She joined NOAA as a National Research Council associate in 2007. Sinead studied at University College London and received an M.Sci. in Earth and Space Science in 2002, and a Ph.D. in 2007, for a dissertation on satellite laser altimetry over sea ice.

Her main interests lie in remote sensing of the Earth's polar regions using satellite and airborne altimetry for marine geophysics and cryospheric investigations. Current research topics include the seasonal and inter- annual variability of Arctic sea ice thickness and volume, the mean dynamic topography and circulation of the Arctic Ocean, and the marine gravity field of the Arctic Ocean. A major component of this research involves analyses and cross-comparison of altimetry data from satellite missions including ICESat, CryoSat-2, Envisat, and ERS-2, as well as aircraft missions such as NASA's Operation IceBridge. Sinead currently serves as a member of the NASA ICESat-2 Science Definition Team and the NASA Operation IceBridge Science Team.
