Biographical Sketches of Committee Members
Dr. John E. Hobbie is a distinguished scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts, and former director of its Ecosystem Center. He also leads the Arctic Long Term Ecological Research Project of the National Science Foundation. His research interests include arctic and antarctic limnology, estuarine ecology, and the global carbon cycle. Over 30 years ago, Dr. Hobbie began studying the role of natural assemblages of microbes in ecosystems, leading him to develop and apply methods for measuring the kinetics of uptake of organic compounds by bacteria using radiolabelled substrates. He later developed methods for measuring the mineralization of organic compounds to CO2 and for visualizing and enumerating bacteria present in natural water samples using DNA specific stains. He also studies larger systems in estuaries and arctic tundra lakes. He has served as a member of the NRC’s Ocean Studies Board and the Polar Research Board as well as on several other NRC committees, including the Committee to Review Community Development Quotas (Chair) and the Committee on Health and Ecological Effects of Synfuels Industries (Vice Chair). Dr. Hobbie received his doctorate in zoology in 1962 from Indiana University. He is chair of this committee because of his international stature as a polar scientist, his prior chairing experience with NRC, and his lack of involvement with subglacial lake exploration to date.
Ms. Amy Baker is the owner of Technical Administrative Services (TAS), a technically based service organization that provides technical and administrative support focusing specifically on the needs of the international scientific community. Over the past 6 years under TAS auspices she has participated in research for new biological methods that are currently under development for supplemental inclusion in NASA’s planetary protection procedures. As senior engineer with Lockheed Martin Astronautics, Ms. Baker worked as the Technical Lead for the Planetary Protection Laboratory for the Mars Surveyor Program and the Chemical Technology Laboratory.
