Cognitive science · Dartmouth College

JR Tibbetts

I’m a cognitive science student at Dartmouth, concentrating in AI, class of 2028. Here’s where my time goes.

What I’m up to

Research

Research assistant in Steven Frankland’s lab, studying how large language models manipulate information held in context. Our paper on backward digit span was published at CogSci 2026.

Research & classes

Theater

I design and program lighting for Dartmouth shows and run production for Displaced Theater Co. In fall 2025 I lit Ride the Cyclone with eight PAR cans and one tech rehearsal.

Shows & photos

Outside

I love cycling and hiking, usually somewhere in the mountains and back roads of northern New England. I’ve hiked all 48 of New Hampshire’s 4,000-footers.
