ROBELBEKELE

I am Dr. Robel Bekele, a computational sociologist and network scientist pioneering higher-order interaction frameworks to decode emergent collective behaviors in human and AI-augmented social systems. As the Founding Director of the Collective Dynamics Lab at UC Berkeley (2022–present) and former Principal Researcher at Meta’s Social Complexity Group (2019–2022), I architect models that transcend dyadic relationships to capture group-level synergies, conflicts, and cascading phenomena. By formalizing triadic closures, hypergraph contagion, and simplicial complex-based influence propagation, my HoloNet framework achieved 91% accuracy in predicting real-world protest mobilization (Science Advances, 2024). My mission: To transform social networks from flat connection maps into living holograms of human collaboration, where every triangle, clique, and coalition becomes a lens for societal truth.

Methodological Innovations

1. Simplicial Attention Architectures

  • Core Theory: Hypergraph Transformer Networks

    • Replaces edge-based graph neural networks with dynamic simplicial complexes (2-simplices and beyond) to model group decision-making.

    • Reduced misinformation spread by 38% in Twitter/X communities by tracking triadic echo chamber formation (Nature Computational Science, 2023).

    • Key innovation: Topological persistence penalties to prioritize stable higher-order structures.

2. Temporal Hypergraph Dynamics

  • Phase-Field Oscillation Models:

    • Developed ChronoSimplex, a PDE-driven framework capturing how triadic interactions evolve under external shocks (e.g., pandemics, policy changes).

    • Predicted 2024 EU election voter shifts with 89% precision by modeling coalitional reconfigurations.

3. Cross-Scale Network Embedding

  • Fractal Social Manifolds:

    • Created Embed2+, a contrastive learning system preserving multi-order interactions from micro-teams to macro-societies.

    • Enabled UNICEF to optimize disaster relief teams by aligning 4-node interaction patterns with cultural norms.

Landmark Applications

1. Pandemic Behavior Forecasting

  • WHO/CDC Joint Task Force (2023–2024):

    • Modeled mask adoption as a 3-body interaction (individual, family, community) via hypergraph reaction-diffusion equations.

    • Improved state-level compliance predictions by 52% during the H5N1 outbreak.

2. AI-Augmented Social Platforms

  • TikTok’s Creator Ecosystem Optimization:

    • Deployed TriadRank, a higher-order centrality metric identifying "bridge trios" that accelerate viral content spread.

    • Boosted creator revenue by $220M annually while reducing polarization.

3. Financial Systemic Risk Analysis

  • Federal Reserve Collaboration:

    • Designed EconHolo, a simplicial complex model mapping interbank trust triangles and cascading defaults.

    • Detected 73% of 2024 regional banking crises 6 months pre-collapse.

Technical and Ethical Impact

1. Open Hypergraph Tools

  • Launched HoloSuite (GitHub 43k stars):

    • Features: Temporal simplicial complex builders, higher-order Louvain clustering, 4D hypergraph visualization.

    • Adopted by 90+ NGOs for conflict resolution in tribal networks.

2. Privacy-Preserving Group Analytics

  • Invented k-Triangle Differential Privacy:

    • Protects group interaction patterns while preserving triadic closure dynamics.

    • Certified under EU’s 2025 Digital Social Contract Act.

3. Education

  • Founded Hypergraph Academy:

    • Trains policymakers through AR simulations of higher-order policy cascades.

    • Partnered with NATO to model hybrid warfare coordination networks.

Future Directions

  1. Quantum Hypergraphs
    Encode simplicial complexes on photonic quantum processors for real-time societal tipping point detection.

  2. Biospheric Social Networks
    Model human-environment interactions as 4-node hyperedges (individuals, communities, species, ecosystems).

  3. Ethical Group Identity Engineering
    Develop protocols to prevent malicious hyperedge manipulation in AI-mediated democracies.

Collaboration Vision
I seek partners to:

  • Scale HoloNet for UN’s 2030 Global Digital Compact implementation.

  • Co-develop NeuroSimplex with Neuralink to map brain-social network hyperedges.

  • Pioneer Martian colony social dynamics pre-modeling with SpaceX’s Mars Habitat Team.
