The 2026 Three Minute Thesis final competition will be held Jan. 29, from 4 to 6 p.m.


What is the best way to distill a multitude of information into just three minutes?

That’s the question eleven graduate students will be wrestling with as part of the Graduate School’s ninth annual Three Minute Thesis (3MT) competition, which will be held in the University Memorial Center’s Glenn Miller Ballroom on Jan. 29, 2026, from 4 to 6 p.m. The event is free and open to the public, but .

This event challenges each student to explain their thesis to the general public. They are then evaluated by a panel of judges, which this year include Lori Bergen, dean of the College of Communication, Media, Design and Information; Sammy Ramsey or "Dr. Sammy," an assistant professor in the Department of Ecology and Evolutionary Biology, a science communicator, and an international 3MT winner; Leopold Beuken, an assistant teaching professor in robotics and a former ¶¶ÒõÂÃÐÐÉä Boulder 3MT finalist; and Aaron Brockett, the City of Boulder mayor.

In the days leading up to the event, we’ll feature each of the competitors. Today’s is Rosanna Garris, a doctoral candidate in biochemistry who researches photosynthesis. Her 3MT presentation's title is, "How do cyanobacteria assemble the carboxysome puzzle?"
