Mary-Elena Carr

Dr. Carr, biological oceanographer, is the Associate Director of the Columbia Climate Center at the Earth Institute, Columbia University in New York City.

To meet the challenge of climate change, Dr. Carr coordinates multi-disciplinary education initiatives and leads research at the boundary of social and physical sciences, including projects that evaluate the impact of government policies on greenhouse gas emissions and responding to claims of those skeptical of climate science. She founded the Columbia Climate Center blog, Climate Matters@Columbia, to meet the Climate Center mission to improve communication between climate scientists and the users of climate information from the general public to policy makers.

Before joining Columbia University, she carried out research in oceanography. As a Research Scientist at Cal Tech's Jet Propulsion Laboratory between 1996 and 2005, she used observations made from satellites and numerical models to quantify the pathways of carbon into and within the ocean. Between 2005 and 2007 Carr was Associate Program Director in Biological Oceanography at the National Science Foundation. She has been a member of the scientific steering committees of the U.S. Ocean Carbon and Biogeochemistry program and the international Integrated Marine Biogeochemistry and Ecosystems Research program. She received her Ph.D. from Dalhousie University and her B.Sc. and M.Sc. from the University of Barcelona.

C-H Christina Cheng

Dr. Cheng is an associate professor in the Department of Animal Biology and the Graduate Program of Ecology, Evolution and Conservation Biology at the University of Illinois, Urbana-Champaign. Her ongoing research aims at understanding the evolutionary changes in genes, gene expression, and genomes, including the innovation of crucial cold-adaptive traits, such as the antifreeze proteins in polar teleost fishes, in response to strong selection pressures from the freezing polar seas.

Her polar fish research spanned over 2 decades in the Antarctic and 12 years in the Arctic.  To fully appreciate the linkage between environmental selection and evolutionary responses, her work integrates past and present polar thermal histories, species evolutionary history, organismal physiology, protein structure-function, molecular evolution, and more recently  transcriptomes and whole genome sequence analyses.  The clear evolutionary mechanisms of polar fish antifreeze protein genes that she, her students, and co-workers deciphered have become prime examples of molecular evolution of genetic novelty in both academic and popular science texts.  Recent comparative transcriptome analyses of Antarctic and non-Antarctic fish species by her and her collaborators have provided the first system-wide view of cold-driven evolutionary shifts in gene transcription and genome content in Antarctic notothenioid fish.  She is a prime driver in a joint effort between her group, the Institute of Development and Genetics of the Chinese Academy of Sciences, and BGI, in whole genome sequencing and characterization of the first Antarctic notothenioid species — the Antarctic toothfish — expected to reach completion in 2012.

Mark A. Fahnestock

Dr. Fahnestock received a B.S. in Geology from the University of Rochester in 1984 and a doctorate in Geology from the California Institute of Technology in 1991. Since that time, he has worked as a glaciologist investigating ice flow mechanics and surface conditions on the large ice sheets. After studying Alaskan glaciers as a graduate student, he moved to NASA Goddard Space Flight Center to investigate surface conditions and ice flow in Greenland and Antarctica. He took a position at the University of Maryland in 1995, working as an Assistant Research Scientist in a cooperative center for Earth System Science (now the Earth System Science Interdisciplinary Center). He started at the University of New Hampshire in May 2002.

His research focuses the role of land-based ice in the earth system. Results from work with numerous collaborators have included the recognition of a large ice stream in northeast Greenland and of the rapid basal melting likely responsible for this rapid ice flow; the first high-resolution radar mosaic of an ice sheet, illustrating both flow features and firn conditions on a large scale; development of a relationship between surface melting and the failure of ice shelves on the Antarctic Peninsula; contributions to the use of InSAR for mapping ice-flow velocity and surface topography; techniques for mapping detailed topography from visible-band satellite imagery; the recent history of ice flow variations on the Ross Ice Shelf mapped from enhanced imagery; and work on the controls on rapid ice flow in Antarctica and Greenland. He has also contributed to work on measuring ice discharge in Greenland and has participated in two Antarctic and four Greenland field excursions. His recent interests focus on the controls underlying rapid ice flow and on atmospheric interactions that determine surface conditions on the large ice sheets. The primary tools for this work are satellite-derived and surface observations and interactions with ice sheet modelers.

Recent community service includes sitting on the Alaska SAR Facility Users Group, an NRC committee to advise NASA about Polar Geophysical Data Sets, the Radarsat Antarctic Mapping Project Scientific Advisory Group, the scientific steering committee for NSF ARCSS Arctic-CHAMP (pan-Arctic Community-wide Hydrological Analysis and Monitoring Program) and serving as an Associate Editor for JGR Atmospheres.

She received her MA and Ph.D. from the Department of Anthropology at the University of California, Berkeley. Dr. Green also received a Master in Public Health from The Johns Hopkins University. Her research, though divergent in orientation, converges around the central theoretical problematic, of how to think dialectically about complex issues of culture, community, violence, and suffering. Her work attempts to trace historical shifts in vulnerability, particularly among peoples across the Americas whose primary identity is indigenous. Dr. Green conducts field research in rural Guatemala, the U.S.-Mexico border, and rural Alaska. Her monograph Fear as a Way of Life: Mayan Widows in Rural Guatemala was published by Columbia University Press (1999) is soon to be published in Spanish in Guatemala.

To Die in the Silence of History: Tuberculosis among Yup’ik peoples of southwestern Alaska is in manuscript preparation. This 3-year ethnographic and archival research project, funded by the National Science Foundation, explores the social consequences of the tuberculosis epidemics that ravaged Native communities, especially the Yukon-Kuskokwim Delta region during the mid-twentieth century. The manuscript highlights the social consequences of the tuberculosis epidemics of the twentieth century that have been largely overlooked in understanding contemporary Yup’ik lives.

Dr. Green current research, The Invisible Wounds of War, also funded by the National Science Foundation, examines the ways in which Yup’ik combat veterans from Native villages across southwestern Alaska reintegrate into communities with the accompanying stresses of combat. This research seeks to grasp the human and social consequences of war on Yup’ik men’s lives who have served in combat in the U.S. military from three eras — the Vietnam War, the First Gulf War, and the ongoing conflicts in Iraq and Afghanistan.
