Gerald Gobel

Greetings. I am Gerald Gobel, a computational topologist and machine learning researcher dedicated to redefining dimensionality reduction through topological data analysis (TDA). With a Ph.D. in Mathematical Data Science (Stanford, 2024) and leadership of the TDA-Redux Consortium at the Max Planck Institute, my work bridges algebraic topology, geometric deep learning, and manifold learning to combat the "curse of dimensionality" in AI systems. My mission: "To compress the infinite complexity of high-dimensional data into human-interpretable low-dimensional spaces, preserving not just distances but the soul of data—its topological essence."

Theoretical Framework

1. Persistent Homology-Guided Projection

My methodology TopoMap integrates:

Multiscale Persistence Diagrams: Encoding topological features (connected components, loops, voids) as optimization constraints.

Morse Theory Alignment: Mapping critical points of data manifolds to low-dimensional embeddings.

Wasserstein Topological Loss: Minimizing topological distortion between original and reduced spaces.

2. Quantum-Inspired Topological Compression

Developed Q-TopoReduce, a hybrid classical-quantum pipeline:Key Innovations

1. Persistent Homology-Aware t-SNE

Created PH-t-SNE, augmenting t-SNE with:

β₁-cycle preservation for maintaining functional connectivity in fMRI data.

3× improvement in identifying Alzheimer’s pre-symptomatic states (ADNI dataset).

Patent-pending topology-weighted KL divergence metric.

2. Topological Autoencoders

Designed TopoAE, a neural architecture featuring:

Persistent homology regularization layers.

Morse complex alignment loss.

Achieved 98.5% MNIST reconstruction accuracy with 2 latent dimensions (vs. 85% for vanilla AE).

3. Dynamic Manifold Unfolding

Introduced TopoFlow, a temporal reduction framework:

Tracks homology evolution in longitudinal cancer omics data.

Predicted breast cancer metastasis 18 months earlier than standard methods (AUC=0.94).

Transformative Applications

1. Cosmic Web Analysis

Partnered with ESA on GalaxyTopo:

Reduced 10^8D galaxy survey data to 3D while preserving large-scale filamentary structures.

Identified 23 dark matter voids undetectable by PCA/UMAP (Nature Astronomy, 2025).

2. Pandemic Mutation Tracking

Deployed ViralTopo during COVID-27 outbreak:

Compressed 100,000D spike protein variants to 2D visualization.

Enabled real-time identification of vaccine-evading strains (WHO recognition award).

3. Materials Science Revolution

Collaborated with CERN on AtomRedux:

Reduced 1M-dimensional quantum material states to 3D topological descriptors.

Accelerated high-temperature superconductor discovery by 50×.

Methodological Contributions
