  • Brief Bio

    Dr. Brucker has been working on microwave remote sensing of the cryosphere since 2007. He joined Universities Space Research Association (USRA) GESTAR in May 2011, and now serves as a Senior Scientist & Manager. He obtained a MSc in Physics from the University of Clermont-Ferrand, France in 2006 and his PhD in Environmental Earth Science System in October 2009 from Grenoble Alpes University, France, after three years at Laboratory of Glaciology and Geophysics of the Environment (LGGE), since then renamed Institute for Geosciences and Environmental research (IGE). In 2015, he earned a Professional Certificate in Project Management from Georgetown University, Washington, DC. Dr. Brucker studies multiple elements of the cryosphere (ice sheets, sea ice, and seasonal snow packs) using air- and space-borne microwave remote sensing observations and modeling. He has participated in several polar deployments (Antarctica, Greenland, Northern Canada) and in 2016-2017, he led NASA SnowEx's Ground Based Remote Sensing activities.

    Research Interests

    Remote sensing of snow/ice covered Earth's polar and sub-polar regions

    Dr. Brucker's research focuses on understanding remotely sensed microwave observations of snow-covered polar and sub-polar regions (i.e. sea ice, ice cap and terrestrial snow packs). The goal of his projects is to contribute to the comprehension of the relationships between both passive and active microwave observations and snow/ice physical properties using modeling approaches to provide climate-related variables to the community for the satellite era. To that end, he works on developing algorithms and contributes to state-of-the-art multilayer snow evolution and emission models. He has published more than 40 papers on these topics, participated in a dozen field campaigns, including polar deployments in both hemispheres, and led the NASA SnowEx Ground Based Remote Sensing activities in 2016-2017.

    Brief Bio

    Dr. Brucker has been working on microwave remote sensing of the cryosphere since 2007. He joined Universities Space Research Association (USRA) GESTAR in May 2011, and now serves as a Senior Scientist & Manager. He obtained a MSc in Physics from the University of Clermont-Ferrand, France in 2006 and his PhD in Environmental Earth Science System in October 2009 from Grenoble Alpes University, France, after three years at Laboratory of Glaciology and Geophysics of the Environment (LGGE), since then renamed Institute for Geosciences and Environmental research (IGE). In 2015, he earned a Professional Certificate in Project Management from Georgetown University, Washington, DC. Dr. Brucker studies multiple elements of the cryosphere (ice sheets, sea ice, and seasonal snow packs) using air- and space-borne microwave remote sensing observations and modeling. He has participated in several polar deployments (Antarctica, Greenland, Northern Canada) and in 2016-2017, he led NASA SnowEx's Ground Based Remote Sensing activities.
