Professor Kathleen Campbell
BSc(Hons) (University of California), MSc (University of Washington), PhD (University of Southern California)
Kathy is a geologist, paleoecologist and astrobiologist. The broad theme of her research is paleoecology - the interaction of ancient organisms with their surrounding environments - whether they were living in normal marine environments, along geologically dynamic active margins, nestled within coastal dunes and marshes, or are/were surviving in harsh 'extreme' environments such as undersea cold hydrocarbon seeps or terrestrial hot springs. Her extremophile / extreme environment studies have broad implications for questions concerning the origin and nature of early life on Earth and whether life ever existed on Mars.
Kathy was educated along the geologically active margin of the western USA – from the University of California (Santa Cruz, BSc), to U Washington (Seattle, MSc), to U Southern California (Los Angeles, PhD). Field work in coastal Washington’s rain forest prepared her for the often wet and bush-clad conditions she regularly encounters on North Island field excursions. Even now she is struck by similarities in geology and landscapes between the two regions. In mid-1997, the University of Auckland enticed her from a post-doctoral position at NASA Ames Research Center (Exobiology Branch) in California to take up paleoecological and paleoenvironmental teaching and research in the Geology Department, now part of the School of Environment. Since then she has co-supervised >60 post-graduate students, and has worked with numerous colleagues on multi-disciplinary research projects, both in New Zealand and overseas. Kathy is a member of the GSNZ, RSNZ, GSA, SEPM (Society for Sedimentary Geology) and the Paleontological Society. She is a Fellow of the Royal Society Te Aparangi. She is director of Te Ao Marama - Centre for Fundamental Inquiry - based in the Faculty of Science at the University of Auckland, which is dedicated to research and outreach activities on the origin and evolution of the Universe and its life. Kathy is the Chair of the Trustees of the New Zealand Astrobiology Network Trust. She participated in the 3rd Mars landing site selection workshop, where the Columbia Hills hot spring site that her team advocated for was chosen as a finalist for the NASA Mars 2020 mission. She is part of an international team of scientists reporting to NASA on the relevance of Mars Sample Return. She is an associate editor or editorial board member on the journals Scientific Reports, PALAIOS, Geobiology, and Palaeontologia Electronica.
Current research is focused on marine hydrocarbon seeps and terrestrial hot-springs as analogues for early life settings and astrobiological targets on Mars and Icy Worlds -- at field sites in New Zealand, Argentine Patagonia, South Africa, Western Australia and the western USA -- in collaboration with groups from the University of New South Wales (Australia); NIWA (New Zealand); U Washington, Calif. Academy of Sciences, Arizona State University, USGS (USA); Leeds Univ (UK); MARUM-GEOMAR (Germany); UNLP (Argentina); and CNRS (Orléans, France).

Current Major Research Focus Areas –
1. Life in Extreme Environments:
i) Undersea hydrocarbon seeps:
Evolution of chemosynthesis; biogeography of vent/seep taxa through geologic time; seep carbonate sedimentology and diagenesis; linkages amongst paleohydrology, tectonics, hydrocarbon generation/migration, and organism distribution in active margin settings. Projects in New Zealand (onshore & offshore), western North America, Alaska.
ii) Terrestrial thermal spring deposits:
Ground-truth for hypotheses about the origin and evolution of life on Earth and elsewhere; assessment of biogenicity; microbial fabric analysis; paleoenvironmental gradients in hot spring settings; impact of diagenesis; applications for epithermal exploration. Projects in New Zealand’s Taupo Volcanic Zone, Coromandel and Northland; Argentinean Patagonia.
iii) Settings for early life on Earth and hydrothermal systems: Evaluating the paleoenvironmental context of Archean (>2.5 billion year old) microbe-sediment systems, and comparing with younger hot spring deposits. Projects in Josefsdal Chert, Barberton Greenstone Belt, South Africa and Pilbara craton, Western Australia.
2. Use of Trace Fossils in High-Resolution Facies Architecture and Paleoenvironmental Analyses:
Ancient organism behaviour and activity are recorded in trace fossils, making them sensitive paleoenvironmental indicators. Integrative studies utilising sedimentology, invertebrate paleontology and ichnology (study of trace fossils) are especially useful for tracking ancient shorelines (i.e., sea-level change), the most significant paleogeographic datum in sequence stratigraphic analysis, employed routinely in petroleum exploration and sedimentary basin reconstructions. Current focus is on traces reflecting estuarine dynamics, compound-complex traces demarcating plant-insect interactions in coastal dune deposits, and marine shelf storm-tide-flood signatures. On-going studies of Quaternary to modern, marginal marine deposits of Northland, New Zealand, Mesozoic-Cenozoic marine sedimentary sequences of the western U.S.
