Astrobiology: Life in the Universe

NASA Astrobiology Institute (NAI)


  1. Seminars

    The Director’s Seminar series features talks from scientists who are invited by the NAI Director to present their research results to the community. A primary goal of the seminars is to encourage interdisciplinary collaboration across NAI teams and within the astrobiology community at large. These seminars are open to all, including the general public; however, the target audience is researchers and students who are engaged in astrobiology. While the seminars are technical in nature, speakers are encouraged to develop presentations that can be understood by colleagues from a variety of disciplines across the field. The talks are typically 50 minutes long, with time at the end for questions and discussion.

    The Forum for Astrobiology Research (FAR) seminar provides an opportunity for graduate students to present their research results, and to meet as a student community for mutual encouragement and support. FAR science presentations are typically 20-30 minutes each, with several students presenting during one virtual event. On occasion, the FAR seminar will be devoted to group discussion and planning activities.

    The University of Washington seminar series is hosted by the NAI UW alumni team from their campus in Seattle. NAI provides technical support for the seminar series and produces podcasts of the presentations. The talks are typically 50 minutes long, with time at the end for questions and discussion.

    Other virtual seminars, such as workshops and summer student presentations, are hosted by NAI. These are typically scheduled as needed and vary in length, content, and target audience.
