ERICMOSLEY

I am Dr. Eric Mosley, a temporal topology researcher and applied mathematician pioneering adaptive topological frameworks for non-stationary time series. As the Founding Director of the Dynamic Data Topology Lab at Stanford University (2020–present) and former Chief Scientist at Microsoft’s Temporal Analytics Group (2016–2020), I integrate topological data analysis (TDA), nonlinear dynamics, and stochastic geometry to decode complex temporal patterns in evolving systems. My TopoTime framework, which quantifies non-stationarity through persistent homology and Wasserstein metric learning, achieved a 52% improvement in forecasting financial market regime shifts compared to traditional ARIMA-LSTM hybrids (ICML 2024 Outstanding Paper). My mission: To transform noisy, drifting time series into structured topological manifolds, enabling machines to "see" phase transitions, anomalies, and hidden dependencies through the lens of algebraic topology.

Methodological Innovations

1. Dynamic Persistence Homology

• Core Framework: Time-Aware Mapper Algorithm

  • Captured time-varying topology by sliding window filtrations coupled with Čech complex deformations, adapting to concept drift in real time.

  • Reduced false anomaly alerts in IoT sensor networks by 44% via multiscale topological stability scoring (KDD 2024).

  • Key innovation: Entropy-weighted persistence diagrams to prioritize topologically critical transitions over stochastic fluctuations.

2. Non-Stationary Feature Fusion

• TopoDyna Architecture:

  • Fused time-frequency features (wavelets) with topological signatures (Betti numbers) using attention-based graph neural networks.

  • Predicted epileptic seizures 8 minutes in advance with 93% AUC-ROC on EEG datasets by isolating pre-ictal topological phase shifts.

3. Topological Regime Discovery

• Persistence-Driven Clustering:

  • Developed RegimeShift, an unsupervised method to partition time series into regimes via Wasserstein barycentric clustering of persistence landscapes.

  • Identified 4 novel market states in cryptocurrency trading, validated by NASDAQ’s volatility arbitrage algorithms.

Landmark Applications

1. Financial Crisis Forecasting

• World Bank Global Risk Initiative:

  • Deployed TopoFinance, a TDA-driven platform analyzing 50+ macroeconomic indicators across 30 nations.

  • Predicted the 2024 Asian currency crisis 3 months early by detecting topological fractures in sovereign debt yield curves.

2. Climate Tipping Points

• UN IPCC Collaboration:

  • Built ClimateTopo, a spatiotemporal model tracking Arctic ice melt dynamics through persistent homology of satellite temperature series.

  • Revealed a critical bifurcation point in Greenland’s ice sheet stability, informing COP29 mitigation strategies.

3. Medical Prognostics

• Mayo Clinic Partnership:

  • Created HealthHorizon, a patient-specific TDA engine analyzing EHR time series to predict sepsis onset 6 hours before clinical markers.

  • Reduced ICU mortality by 31% in a 10,000-patient trial via early topological risk stratification.

Technical and Ethical Impact

1. Open-Source Topology Tools

• Launched TopoFlow (GitHub 32k stars):

  • Tools: Time-warped persistence visualizers, non-stationary TDA benchmarks, and regime transition simulators.

  • Adopted by 200+ institutions for fraud detection, epidemiology, and energy grid resilience.

2. Edge Computing Integration

• Intel Neuromorphic Chip Collaboration:

  • Co-designed TopoCore, an FPGA-embedded TDA accelerator achieving 40x speedup in real-time persistence diagram updates.

  • Enabled subsecond topology analysis for high-frequency trading and autonomous vehicle telemetry.

3. Interdisciplinary Education

• Founded Temporal Topology Collective:

  • Trained 1,500+ analysts in "topological thinking" for finance, healthcare, and climate science through VR-based time series sandboxes.

  • Partnered with Coursera to launch the first TDA specialization for non-stationary data.

Future Directions

1. Topological Causal Inference
   Extend TDA frameworks to disentangle Granger causality in non-stationary systems via directed persistent homology.

2. Quantum-TDA Hybrids
   Collaborate with IBM Quantum to encode persistence diagrams into qubit states for noise-resilient temporal pattern recognition.

3. Ethical Topology Audits
   Develop topology-based fairness metrics to detect discriminatory regimes in algorithmic decision-making timelines.

Collaboration Vision
I seek partners to:

• Scale TopoTime for the European Central Bank’s systemic risk monitoring network.

• Co-develop NeuroTopo with the Allen Institute to map brain dynamic connectivity in neurodegenerative diseases.

• Pioneer TopoPolicy frameworks with the UN to model geopolitical conflicts as multi-scale temporal topology shifts.
