Networked Speaker Series

The Center for Dark Energy Biosphere Investigations (C-DEBI) is a “networked” Science and Technology Center (STC), gathering expertise, ideas, and participation from institutions across the U. S. and around the world. C-DEBI is particularly interested in opening and developing communication between participants separated by thousands of miles. C-DEBI participants gather in person at meetings periodically, but we can also link STC members using modern web tools. C-DEBI is continuing the Networked Speaker Series (begun in Fall 2011) as a means to enhance communication and the exchange of ideas among our community.

Call for Nominations

Speaker nominations for the 2020 series are now closed.

Check out the Ocean Discovery Lecture Series which brings the scientific explorations and discoveries of the International Ocean Discovery Program to academic research institutions, museums, and aquaria.  Nominate a deep biosphere speaker or apply to host one at your institution.

PDF version of the nomination request

C-DEBI seeks nominations for three speakers for the 2020 program year. Potential speakers can be nominated by colleagues, mentors, or those mentored by C-DEBI participants; they may also self nominate. Selected C-DEBI Networked Speakers will make a presentation online, using video conferencing tools, with assistance from the C-DEBI main office at USC. Presentations are to be about 30 minutes in length, with time allocated for questions and discussion.

We would like to have three presentations during the 2020 academic year, ideally one in the spring, one in early summer, and one in the fall. No travel will be required either to make a presentation or to listen/participate in a presentation. Presentations will be recorded for later online playback by participants or those who could not “attend” the live web event.

Nominated C-DEBI Networked Speakers should be capable of combining compelling visual materials with the ability to communicate effectively to a broad audience. We are particularly enthusiastic about giving young researchers a chance to present work to the C-DEBI community. Being selected to be a C-DEBI Networked Speaker is an honor. Once speakers are selected, presentation dates and times for presentations will be determined and announced, along with instructions for connecting over the web.

Please forward nominations comprising a single PDF packet containing the following information:

  1. A brief cover letter describing potential presentation topic(s) and evidence that the nominee can make a suitably broad and compelling presentation
  2. Nominee CV (short format, 1-2 pages)

Please name the PDF nomination file, “NSS-Nom_Lastname.pdf” and email to Rosalynn Sylvan (rosalyyl@usc.edu) using the subject line: “C-DEBI Networked Speaker Series Nominee”. Speaker selection will begin immediately and will continue until all 2020 slots are filled.
