Zann Gill
Director, NASA U
(M.Arch. Harvard) began her career as a researcher for Buckminster Fuller on tensegrity structures (lightweight, rapidly deployable discontinuous compression structures) and at the Institute for Lightweight Structures (University of Stuttgart, Germany). Early interest in cross-disciplinary innovation led to research on how evolutionary models underpin intellectual creativity and collaborative problem-solving. Her 1986-7 submission to the international competition "Kawasaki: Information City of the 21st Century" tied with Matsushita Corp. for first place and won the Award of the Mayor of Kawasaki. Competition sponsors were the Japan Association for Planning Administration and Mainichi Newspapers with cooperation of ten ministries and three agencies of the Japanese government. She proposed how a networked think tank could guide evolving, emergent urban revitalization from within.
The practical focus of her work at NASA is also on how to tap individual creativity and expertise in a group collaborative problem-solving process. She is now applying those evolutionary principles to the enlistment of a range of scientific experts in the design of the NASA U program and development of its outreach network. Her published papers focus on CPSEs (Collaborative Problem-Solving Environments) as vehicles to support collaborative problem-solving. She is currently writing a book on the process of hypothesis construction in origin of life, alife, and AI (first presented as a paper at the International Congress on the Origin of Life 2002). > Web site link

Jonathan D. Trent
Associate Director, Bio-Info-Nano Technology in Astrobiology
received his Ph.D. in Biological Oceanography at Scripps Institution of Oceanography studying marine microbiology. Dr. Trent spent six years in Europe at the Max Planck Institute for Biochemistry in Germany, the University of Copenhagen in Denmark, and the University of Paris at Orsay in France. In Europe he studied biochemistry and molecular biology and he returned to the U.S.A. to work at the Boyer Center for Molecular Medicine at Yale Medical School for two years before establishing a biotechnology group at Argonne National Laboratory. In 1998 he moved to NASA Ames Research Center to be part of NASA’s Astrobiology program, which is focused on understanding the limits of life on Earth and on exploring the possibilities of finding life beyond Earth.
For many years Dr. Trent has conducted research on the molecular adaptations that allow microbes to live in habitats that seem inhospitably extreme to us. His research on these so called “extremophiles” has focused on understanding the role of a specific class of proteins known as heat shock or stress proteins that are particularly abundant in organisms living in hot sulfuric acid (85°C/pH 2). While seemingly esoteric, the stress proteins in extremophiles proved to be closely related to a class of human proteins that were of unknown function (Trent et al. Nature vol. 354: 490-493). His group is now studying these proteins in both extremophiles and humans to determine their critical function.
In 1999 Dr. Trent proposed that the self-assembly properties of biomolecules combined with genetic engineering can be used as significant ‘tools’ for developments in nanotechnology. His group at NASA Ames Research Center has demonstrated that genetically modified proteins from extremophiles that self–assemble into two dimensional arrays can be used as templates for organizing conducting and semiconducting nanoparticles with nanometer resolution. His group continues to explore the extremes of biology and how biomolecules interface with nanotechnology. > Web site link

Tim Castellano
has been at NASA Ames for 16 years, first as an aerospace engineer and manager working on space flight projects and more recently (since his 2001 Ph.D in Astronomy and Astrophysics from the The University of California at Santa Cruz) as an observational astronomer seeking transits of extrasolar planets by the photometric method. Before coming to NASA Ames, Tim worked at Fermilab and Lockheed and has a bachelor’s degree from the State University of New York at Stony Brook in Physics and Earth and Space Sciences.
Tim is committed to help communicate the excitement of NASA’s challenges and to help involve the general public and students in NASA missions. The quest for worlds orbiting other stars has occupied the minds of some of history’s greatest thinkers, but only in the last few years has irrefutable proof of the existence of extrasolar planets been found. Searching for transits is an ideal student project because it can literally be done in a backyard, given the right equipment and expertise. This project presents an opportunity rare in modern science, the ability to make fundamental discoveries without access to a multi-million dollar research facility and without having to be a small part of a huge collaboration. The study of extrasolar planets is dynamic; further breakthroughs are just around the corner. Besides his "day job" as an astronomer, Tim also teaches Introductory Astronomy at San Jose State University (where he received his MSAE in 1993).

Friedemann Freund
thinks crystals are fascinating objects, mostly because of their defects and impurities. His research interests lie with defects and impurities in minerals, which derive from their interaction with the common gases/fluids in the natural environment: water, carbon dioxide, nitrogen. He’s found reactions inside the dense matrix of minerals, by which hydrogen, carbon and (probably) nitrogen become chemically reduced, while oxygen anions become oxidized.
Studying these processes has led him to become interested in the Origin of Life, in the nature of the organics in interstellar dust, and in the global oxidation of terrestrial planets. The valency changes among the oxygens turn rocks, which are insulators, into p-type semiconductors. This has opened a door to study non-seismic pre-earthquake phenomena from a new perspective.

Peter Jenniskens
is the Principal Investigator of the NASA and USAF sponsored Leonid Multi-Instrument Aircraft Campaign that studied the recent spectacular Leonid storms for clues about the origin of prebiotic organic molecules on Earth, the dynamics of comet dust ejection, and the impact danger to satellites. The campaign consisted of night time two-plane international research missions to Japan (1998), Israel (1999), CONUS (2001) and Spain (2002), involving ~ 35 participating researchers of 7 nationalities. This included students of the NASA Astrobiology Academy. The 1998 Leonid MAC mission was NASA’s first Astrobiology mission.
Peter is formally trained as an astronomer and laboratory astrophysicist at the University of Leiden in the Netherlands under the tutelage of Professors Harm Habing and Mayo Greenberg, where he did astronomical measurements of interstellar matter at UV, optical, mid-IR, and radio wavelengths, and completed the first survey of Diffuse Interstellar Bands in the optical spectra of obscured stars with F. Xavier Desert. In the laboratory, he investigated the chemical evolution of organic matter under UV photo-processing in the interstellar medium. After his graduation in 1992, he investigated the physical properties of amorphous ices at NASA Ames Research Center’s exobiology branch, using an adapted electron microscope by Dr. David F. Blake.
Since 1995, Peter has been employed with the SETI Institute and works at NASA Ames and SETI on the dynamics of meteor showers, the physical processes in meteors, and the clues they can provide about the origin of prebiotic organic molecules on Earth. He brought to the field the use of modern spectroscopic and imaging techniques. He correctly predicted the return of the 1995 alpha-Monocerotid shower and continues to do field studies of meteor showers. By initiating and organizing the ambitious Leonid storm
observing campaigns, he helped rejuvenate the field of meteor shower research and served as organizer of special sessions at COSPAR, EGU, and AGU and editor of the book on Leonid storm research.

Dr. Pendleton received a B.S. in Aerospace Engineering from Georgia Institute of Technology, an M.S. in Aeronautics and Astronautics from Stanford University, and a Ph.D. in Astronomy and Astrophysics at the University of California at Santa Cruz.
She has held a research position as an astrophysicist at NASA Ames Research Center since 1979. The goal of her research program is to understand the composition of the organic material found in the interstellar medium and to investigate the incorporation of the organic material from space into the early Earth environment. She has found strikingly similar signatures from hydrocarbon molecules in the distant dust of other galaxies, in the dust from our own galaxy, and in carbon-bearing meteorites. This suggests the basic building blocks of life are widespread and available for incorporation into newly forming planetary systems throughout the universe.
Elected a fellow of the California Academy of Sciences in 2003, Dr. Pendleton has published over 60 papers in scientific journals, has edited two scientific books, and has appeared in several PBS programs. She has an asteroid named after her (7165 Pendleton) and is very active in education outreach. Yvonne served as a co-principal investigator for the Voyages Through Time project, a ninth grade level integrated science course on CD Rom and has participated as a Project Astro astronomer for the Astronomical Society of the Pacific since 1994. She makes regularly scheduled classroom visits to local schools and has given public talks on a variety of astronomical topics around the Bay Area. Presented with the NASA Outstanding Mentor award in 1996, she continues to work with students at many institutions and post doctoral researchers at Ames Research Center.

Lynn J. Rothschild
an evolutionary biologist at NASA’s Ames Research Center, is immersed in the field of Astrobiology. She has broad training in biology, with degrees from Yale University, Indiana University, and Brown University. At NASA her research has focused on how life has evolved in the context of the physical environment, both here and potentially elsewhere.
She has co-edited a book on the subject entitled, "Evolution on Planet Earth: The Impact of the Physical Environment" which will be published in the spring of 2003. Rothschild has studied carbon metabolism and DNA damage and repair in the laboratory setting and on algal mats, work that has taken her to field sites in Baja, Yellowstone National Park and thermal areas on New Zealand, and hopefully some day to Mars.
As a result of this work she has become an acknowledged authority in the study of extremophiles, and wrote a critical review on them for Nature (2001). Recent honors have included election to the Presidency of the Society of Protozoologists, and as a fellow to the Linnean Society of London. She is a founding editor of the International Journal of Astrobiology. In the last few years she has made several television and radio appearances, including on the Discovery Channel and ABC World News Tonight, and lectures worldwide, most recently in the Vatican, Windsor Castle and Japan.

Scott Sandford
is a member of Ames' Astrophysics Branch and is a co-leader of Ames’ Astrochemistry Laboratory. He has extensive experience in the fields of meteoritics. He is an editor of the journal Meteoritics and Planetary Science and has helped find many meteorites in Antarctica, some of them quite famous [or perhaps infamous]. Remote Antarctic locations he has worked at include the Allan Hills area, the Lewis Cliff area, and Graves Nunataks. Dr. Sandford also does extensive work in the areas of laboratory astrophysics, astrochemistry, and astrobiology, and participates in infrared astronomy studies using ground-based, airborne, and spaceborne observatories. He has used the combined techniques of infrared astronomy and laboratory astrophysics to identify a number of new molecular species in space, many of interest to exobiology (for example, organic compounds in the diffuse ISM). Current laboratory interests include the study of the physical, chemical, and spectroscopic properties of polycyclic aromatic hydrocarbons(PAHs) and astrophysical ice analogs relevant to interstellar, cometary, and planetary environments.
Dr. Sandford is the Principal Investigator on the AstroBiology Explorer (ABE) MIDEX Mission concept. ABE is a cryogenically cooled infrared telescope that will measure the infrared spectra of a wide variety of objects and environments in space. These spectra will be used to understand the origin and evolution of organic compounds in space. He is also a Co-Investigator on the STARDUST Discovery Mission. The purpose of this mission is to collect a sample from a comet and return it to Earth for study! The STARDUST spacecraft was launched on February 7, 1999 and intercepted Comet Wild 2 on January 2, 2004. The collected sample will be returned to Earth for study in January of 2006. Dr. Sandford also assisted with testing of the sample return capsule filter for the GENESIS
Discovery Mission.
Dr. Sandford’s work has been recognized through a number of awards, including the Antarctic Service Medal, and numerous individual and group honors. He was named an Ames Associate Fellow in 2000.
Many of Dr. Sandford’s major publications can be found here. More complete lists for publications from 1979-1992 and 1993-current are also available.
