Gordon Research Seminar

The Future of Geobiology: Perspectives from Graduate and Postdoctoral Research


January 26-27, 2013


Ventura Beach Marriott
Ventura, CA


Dina M. Bower

Associate Chair:
Jim Schiffbauer

Meeting Description

The Gordon Research Seminar on Geobiology is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas.

The focus of this meeting is to explore the diverse and dynamic field of geobiology . The discussions and presentations will address these main themes:

  • microbial structures in ancient and modern settings
  • taphonomy and micropaleontology
  • biomineralization and the co-evolution of minerals and microbes
  • life detection for applications to early life on Earth and other planets
  • integrating geobiobiology into interdisciplinary research and academic programs

This GRS was held in conjunction with the "Geobiology" Gordon Research Conference (GRC). Refer to the associated GRC program page for more information.
