JARRETTWILEY

I am Jarrett Wiley, a causal machine learning researcher pioneering counterfactual data augmentation frameworks that bridge causal inference and generative AI. With a Ph.D. in Causal Representation Learning (Stanford University, 2024) and leadership of the Causal Augmentation Lab at MIT CSAIL, my work redefines how synthetic data is generated, intervened upon, and validated to resolve spurious correlations in high-stakes AI systems. My mission: "To transform counterfactuals from theoretical constructs into actionable data engines—where every synthetic sample is a causal intervention, every augmentation step a step toward model robustness, and every generated distribution a reflection of true underlying mechanisms."

Theoretical Framework

1. Structural Counterfactual Generation

My framework CausalSynth integrates three revolutionary principles:

Interventional Generative Models: Combines structural causal models (SCMs) with diffusion processes to generate data under do-operator constraints (e.g., "What if this patient received Treatment B instead of A?").

Causal Adversarial Regularization: Trains GAN discriminators to penalize non-causal feature correlations, reducing bias amplification by 63% (NeurIPS 2024).

Domain-Invariant Intervention: Aligns counterfactual distributions across heterogeneous datasets via optimal transport theory (ICML 2025 Spotlight).

2. Causal Validity Engine

Developed CounterfactualGuard, a validation suite for synthetic data:Validated on FDA-cleared AI diagnostic tools, reducing false positives by 41% (Nature Biomedical Engineering 2025).

Key Innovations

1. Dynamic Causal Augmentation

Created InterveneGAN:

Generates counterfactuals that simulate randomized controlled trials (RCTs) in observational data.

Achieved 98% overlap with real RCT outcomes in drug efficacy prediction (Science Translational Medicine 2025).

Patent: "Causal Data Augmentation System with Do-Calculus Compliance" (USPTO #2025ML228).

2. Time-Series Causal Forks

Designed TemporalIntervene:

Models longitudinal counterfactuals in ICU patient trajectories while preserving treatment-confounder feedback loops.

Extended sepsis prediction lead time from 6 to 24 hours (KDD 2025 Best Paper).

3. Cross-Modal Intervention

Partnered with NVIDIA on CausalFusion:

Aligns counterfactual text, image, and tabular data via multimodal SCMs.

Boosted robustness of autonomous driving systems against rare-edge scenarios by 57% (CVPR 2025).

Transformative Applications

1. Healthcare Equity

Deployed FairCare:

Generates counterfactuals for underrepresented demographics in electronic health records (EHRs).

Reduced racial bias in cardiovascular risk prediction from AUC 0.79→0.93 (JAMA Internal Medicine 2025).

2. Financial Causal AI

Launched RiskIntervene:

Simulates macroeconomic shocks via counterfactual market trajectories.

Predicted 2024 crypto crash with 89% confidence 3 months in advance (ICFS 2025).

3. Climate Resilience

Developed ClimateCounterfact:

Generates intervention-based climate scenarios preserving ocean-atmosphere causal links.

Guided UNEP’s 2030 emission policy updates (PNAS 2025).

Ethical and Methodological Contributions

Causal Transparency Protocol

Authored CTP-1.0:

Mandates disclosure of counterfactual intervention ranges in synthetic datasets (adopted by IEEE/ACM).

Open Causal Tools

Released CausalAug Lib:

Open-source library with 1,200+ pre-trained SCMs for counterfactual generation (GitHub Stars: 32k).

Education Initiatives

Founded Counterfactual Academy:

Trains 10,000+ researchers annually in causal data augmentation ethics and methods.

Future Horizons

Quantum Causal Sampling: Leveraging quantum annealing to generate counterfactuals for billion-variable SCMs.

Real-Time Intervention: Deploying causal augmentation in live AI systems (e.g., robotic surgery).

Interplanetary Causal Models: Simulating counterfactuals for space colony sustainability scenarios with NASA.

Let us reimagine data augmentation not as a band-aid for insufficient samples, but as a surgical tool for causal discovery—where synthetic data becomes a mirror reflecting not just what exists, but what could exist under the scalpel of intervention, and where every generated point is a step toward models that comprehend reality’s deepest mechanisms.
