International GCE Webinar

Group photo of attendees of the 2018 GCE Conference held at OSU. The group is standing outside in front of the conference building.

The International GCE Webinar is a monthly webinar series, open to all, featuring talks on cutting-edge applications of genetic code expansion (GCE) technologies as well as advances in the GCE field. It is organized by the Oregon State University GCE4All Research Center and hosted by Rick Cooley and John Lueck. The webinar is meant to be of value to both developers and users of GCE, as well as anyone interested in learning more about it. Speakers will be from around the globe, and we invite speaker and topic suggestions.

Webinar mechanics

The webinars run from October through June and occur on the third Thursday of each month at 10 a.m. Eastern Time (corresponding to 2 p.m. GMT March-October and 3 p.m. GMT November through February). The general format is to give each of the two speakers 30 minutes which we recommend be divided into a presentation of 20-25 minutes followed by 5-10 minutes of discussion.


When possible, seminars will be recorded and made available for viewing on the GCE4All YouTube Channel; as this will not be possible for all seminars, please make it a priority to register for and participate in the live events. Although the seminars are free and open to all, pre-registration is required to get the specific link for each seminar.

Upcoming Webinars

April 20th, 2023


Andrea Cochran (Genentech, Inc.)

Split aminoacyl-tRNA synthetases for proximity-induced stop codon suppression 

Jeffery M. Tharp (Indiana University School of Medicine)

The ability to control gene expression in living cells has many useful applications in biotechnology and medicine. In this talk I will describe the design and engineering of split orthogonal aminoacyl-tRNA synthetases (o-aaRSs) that can be used to tightly control gene expression in bacteria and in human cells. Furthermore, I will describe how these split o-aaRSs can serve as useful tools for detecting protein–protein interactions, including those involved human disease.

GCE Community Networking

A resource available for more extensive discussion and networking among those learning about, using and/or developing GCE technologies is the GCE bulletin board – GCEbb ­– a forum for email-based discussions. More information about the GCEbb, including how to join the email list, can be found at the GCEbb home page. We are looking forward to having you join our GCE conversations!
