THE WORK BEHIND THE PROFILE

Proof of Work

explanationChecked Sep 20, 2026

Auditing Multimodal Generative Systems for Representational and Allocative Harm

Formulated structured auditing protocols for text-to-image and multimodal foundation models, measuring bias propagation across CLIP embeddings, latent diffusion prompt expansions, and synthetic face generation.

Scope & limitations

Balancing automated quantitative metric auditing with contextual qualitative evaluation requires domain-specific sociological input.

Context: CLIP, Stable Diffusion, demographic diversity benchmarking over fine-grained prompt variations.

Model Cards for Model Reporting: Standardizing ML Evaluation Disclosures

Authored the seminal ACM FAccT paper introducing 'Model Cards for Model Reporting', an operational documentation standard that details model architecture, intended tasks, training parameters, out-of-scope uses, and disaggregated demographic evaluations.

Scope & limitations

Static documentation can diverge from deployed weights if model inputs undergo runtime changes or unlogged adapter swaps.

Context: Disaggregated evaluation metrics across intersecting demographic slices and environmental contexts.
