About David Gruber

Project CETI and Whale Translation

David Gruber founded Project CETI (Cetacean Translation Initiative) to pioneer AI-driven translation of sperm whale codas, likening it to 'CETI for whales not SETI for E.T.' [1]. Key achievements include proposing the first sperm whale phonetic alphabet [14], developing WhAM (Whale Acoustics Model) for generating synthetic codas [22], and open-source bio-loggers for multimodal data collection [20]. CETI deploys drones for tag application [21], autonomous robots for tracking [12], and collaborates on legal applications via NYU's MOTH program [17]. Gruber reflects on advisors like Roger Payne in annual reports [16] and launched new websites for outreach [10][13].

Sperm Whale Social Dynamics and Behavior

Gruber's research reveals complex social structures in Caribbean sperm whale units off Dominica, where movements are predictable via LSTM neural networks tied to social bonds [19]. He documented a collaborative birth where non-kin females lifted the newborn, dissolving kinship barriers [23], with detailed video analysis showing shifts in coda styles during events like pilot whale interactions [25]. Acoustic classification via inter-pulse intervals identifies units with 78% accuracy [19], and studies highlight clan-based dialects [14].

Technological Innovations in Marine Research

Gruber advances non-invasive tools: drone-based 'tap-and-go' tagging with 55% success [21], suction-cup bio-loggers recording audio to 967m depths [20], and soft robotics for studying ocean life without harm [3]. These sync high-fidelity hydrophones, GPS, and sensors for AI analysis [20]. Field tests captured 44 hours of sperm whale data across 10 deployments [20], enabling bioacoustic and ML applications [22].

Bioacoustics and Phonetic Structures

Work decodes coda phonology [18], orca vowels/consonants converging with human speech [24], and proposes phonetic alphabets [14]. WhAM generates codas preserving features, aiding classification of rhythm, units, and vowels [22]. Research spans sperm whale codas, emphasizing phonetic and rhythmic patterns [1][3].

Broader Implications: Interspecies Communication and Ethics

Gruber explores whale talk as a model for alien contact [1], ecology [30], and animal rights [bio]. He authored NYT op-eds on talking to whales [36], featured in Time [26], Big Think [28], and Sierra Club [29] on AI translation. Projects empower storytellers [15] and D.S. & DURGA collaborations [11], questioning if whales want human contact [1] and ethical AI use [17].

Public Outreach and Recognition

Podcasts discuss whale communication [1][3], biofluorescence discoveries [3], and vision [podcast 3]. News covers AI animal talk [26][29], whale births [32], and controversies [31]. Gruber is a Rolex Perpetual Planet visionary [3] and National Geographic figure [bio].
