  • “Posters” – short submitted presentations - will be conducted during a session in separate Zoom rooms to allow people to jump between poster topics. The poster title, authors, and zoom link will be included in the program. These sessions will take the form of 2 minute “lightning talks” with Q&A. The emphasis is on giving a short introduction to your work, including upcoming or proposed work that you want to tell the group about.

    The visuals could be provided either through a traditional scientific poster formatted in powerpoint/pdf, active presentations using Prezi (or other tools), a few powerpoint slides or figures, etc.

    Poster presenters should submit the poster authors, title, and a zoom link when registering for the meeting.


To bring together people who are working on subterranean biology so that knowledge and information can be shared and transferred and future efforts to increase knowledge of groundwater ecosystems can be coordinated.

Mission Statement:

The mission of the organizers of TGIF is to encourage collaboration and exchange of ideas and information, and to more efficiently and clearly convey and transfer information to those who need and/or use it.

Problem Statement:

A number of people are currently working on Texas groundwater organisms, however, there is infrequent research coordination and information exchange about the diverse projects and ongoing efforts that can cause barriers for those who want to fully understand groundwater biodiversity, promote efficient dissemination, and effectively use the data for research and management purposes.
