Leadership
Lars Peter Riishojgaard
Director - Earth System Science Interdisciplinary Center (ESSIC)
Executive Director - Cooperative Institute for Satellite Earth System Studies (CISESS)
Dr. Riishojgaard earned his master’s in mathematics and physics in 1989 and his Ph.D. in geophysics in 1992 from the University of Copenhagen. From 1995 to 2007, he held various positions at NASA’s Goddard Space Flight Center. Appointed at the University of Maryland from 2007-2014, Riishojgaard directed the Joint Center for Satellite Data Assimilation, a multi-agency research center focused on improving the use of satellite data for analyzing and predicting the weather, the ocean, the climate and the environment.
In 2014, Riishojgaard joined the World Meteorological Organization (WMO). In his most recent leadership position, Riishojgaard led the development of the Global Greenhouse Gas Watch, which was endorsed by the World Meteorological Congress and recognized at the United Nations climate summit, COP28. Prior to that, he led the development of the WMO Global Basic Observing Network and the overhaul of the WMO Data Policy (formerly known as Resolution 40), which sets the ground rules for the international exchange of all weather and climate data.
Ralph Ferraro
Associate Director - Earth System Science Interdisciplinary Center (ESSIC)
Ferraro is a proud University of Maryland alumnus, having graduated in 1982 with a Master of Science degree in Meteorology. Immediately after graduation, he began working for consulting contractor companies in the local area that supported federal agencies like NASA and NOAA. In 1991, Ferraro joined NOAA as a Physical Scientist where he researched the development of advanced retrieval algorithms for hydrological products with passive microwave sensors. Ferraro was one of the original group of five scientists in SCSB that was formed in 2003. In 2005, Ferraro took on the role of SCSB Branch Chief, which has been co-located with the ESSIC-administered Cooperative Institute for Satellite Earth System Studies (CISESS) (then known as the Cooperative Institute for Climate and Satellites) since 2003. In 2021, he took on the role of Associate Director of ESSIC. In 2023-2024, he served as ESSIC’s Interim Director.
Hugo Berbery
Deputy Director - CISESS
E. Hugo Berbery is a Research Professor at ESSIC and Deputy Director for CISESS, the Cooperative Institute for Satellite Earth Systems Studies. Dr. Berbery, a Fellow of the American Meteorological Society, has research interests in regional hydroclimate variability, monsoon systems and land surface-atmosphere interactions. He is currently serving as co-chair of the International CLIVAR’s Variability of the American Monsoon Systems (VAMOS) Panel and as a member in other international panels.
Andy Negri
Assistant Director - ESSIC
Andrew Negri received his Bachelor’s degree in Atmospheric Science from SUNY-Albany in 1975 and his Master’s degree in Atmospheric Science from Colorado State University in 1978. From 1979-2008, he was a Research Meteorologist at the NASA Goddard Space Flight Center in Greenbelt, MD, using remote sensing to study severe storms and precipitation. He received numerous NASA/GSFC awards including the Exceptional Achievement Award, the Laboratory for Atmospheres Staff Support Peer Award, the Laboratory Award for Outstanding Research paper, and a NASA Acquisition Improvement Award. In 2008, he joined ESSIC as Assistant Director where he is the point-of-contact for new scientist hires, promotions/appointments and strives to execute and enforce ESSIC operational policies.
