A man who listens to whales

David Gruber leads Project CETI, an ambitious scientific effort to decode sperm whale communication by applying artificial intelligence and machine-learning techniques to vast acoustic datasets. He argues that the complex, patterned clicks of sperm whales can be analyzed and mapped to meaningful units much as human languages have been parsed, and he treats the project as a feasible next step rather than a fanciful quest. The initiative combines at-sea fieldwork from research vessels, high-resolution recordings, and computational models to search for structure, syntax, and context in whale vocalizations. Enthusiasts hail it as one of the most audacious scientific undertakings of our time; skeptics dismiss it as a beautiful but unlikely pursuit.

Gruber’s conviction stems from a lifelong, intimate curiosity about other life forms. A New Jersey child who preferred watching insects to socializing, he developed a research trajectory through microbiology, biological oceanography, bacteria-protozoa interactions, and studies of fish, sharks, sea turtles and visual communication before focusing on cetaceans. That background, combined with hands-on field experience and an intuitive approach that privileges kinship with nonhuman minds, informs a methodology that blends natural-history observation with cutting-edge computation in pursuit of translating a nonhuman language.
