Networked Speaker Series

This series was superseded by our C-DEBI Virtual Meeting Series in 2021-2022.  These virtual events were held monthly during the first week of each month, with a regular rotation of science workshops and professional development workshops.

C-DEBI is a “networked” Science and Technology Center, 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 also link C-DEBI members using modern web tools. The Networked Speaker Series highlighted presenters capable of combining compelling visual materials with the ability to communicate effectively to a broad audience. We were 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.

C-DEBI hosted 29 speakers in the Networked Speaker Series from 2011-2021 as a means to enhance communication and the exchange of ideas among our community. Speakers were nominated by colleagues, mentors, or those mentored by C-DEBI participants; they could also self nominate. Speakers made their presentations online, using video conferencing tools, with assistance from the C-DEBI main office at USC. Presentations were about 30 minutes in length, with time allocated for questions and discussion. Presentations were recorded for later online playback by participants or those who could not “attend” the live web event.
