Koletre-Browning University was one of the many universities on the human Inner Colony world of Circumstance. After a young Catherine Halsey continued to defy educatory standards at Endymion Gifted, the university's Dean of Biological Science funded her a trip to Circumstance in 2501 to allow her to attend the school. The dean continued to fund her education until 2507, when she completed two doctoral thesis papers. Graduate students in the Applied Sciences program at the university would later work alongside the Watershed Division and the Materials Group in Project SCLERA to create the P237-THEIATEK optical suite.
