Gruber and collaborators reported discoveries of more than 180 new biofluorescent fish species in 2014, as reported in the New York Times's article, "Fluorescence is Widespread in Fish, Study Finds."
In 2015, he discovered biofluorescence in Hawksbill sea turtles in the Solomon Islands, marking the first time that scientists had observed biofluorescence in a marine reptile.
Field video of this discovery was featured on National Geographic.
Also in 2015, Gruber gave a TED Talk on biofluorescence in sea creatures at Mission Blue II which has been viewed over 2.3 million times.

Gruber and collaborators again had video featured on the National Geographic website  in 2016 after engineering a "shark-eye" camera, which for the first time allowed scientists to view sharks as they see each other.
From 2017-2018, Gruber used his time as a Fellow at the Radcliffe Institute of Advanced Study in order to pursue an in-depth study of jellyfish on topics ranging from their biofluorescence, to their connection to humans and how they are effected by climate change.
Gruber would use this research into jellyfish in order to act as an educator on a TED-ed animation.
In 2018, Gruber promoted marine biology for National Geographic Kids' series "Best Job Ever."

In 2019, Gruber was part of the team responsible for discovering that bromo-tryptophan-kynurenines make sharks biofluorescent, and this work was featured in The New York Times, National Geographic, Science Magazine, on PBS and on CNN.
That same year, Gruber and team were again featured in an article in National Geographic for their discovery of flashlight fish schooling at night using their bioluminescent organs, which opened up the possibility that schooling fish may inhabit even the deep sea, and Gruber led the first study to apply advanced deep machine learning techniques to better detect and classify Sperm Whale bioacoustics.
Gruber is currently working on a related project.
