Generative AI, machine unlearning, and responsible model editing
Selected projects, publications, and patents from my Ph.D. research and applied work — spanning foundation models, diffusion-based generation, and the tools to understand and edit what these models have learned.
Research
Research Interests
The problems I keep coming back to, across papers and production systems.
Machine Unlearning
Selectively removing the influence of specific data, concepts, or identities from trained models without costly full retraining.
Model Steering & Concept Editing
Locating and editing fine-grained concepts inside foundation models using sparse, neuron-level representations.
Mechanistic Interpretability
Understanding what is actually happening inside large models well enough to intervene on it responsibly.
Multimodal Foundation Models
Vision-language models and other multimodal systems, and how their internal representations can be understood and controlled.
Diffusion Models & Generative Video
Text-to-image and text-to-video generation — from diffusion fundamentals to structured, multi-scene video pipelines.
Large Language Models
LLM reasoning and scene-planning as a control layer for downstream generative and multimodal systems.
Selected Work
Research & Applied Projects
A mix of published research, active submissions, and the generative video system built at Valoi.
IEEE IJCB 2025
CURE: Centroid-guided Unsupervised Representation Erasure for Facial Recognition
Removes the influence of specific identities from facial recognition models through centroid-guided, unsupervised representation erasure — without full retraining.
Under Review, IEEE T-BIOM
NEST: Fine-Grained Concept Unlearning via Neuron-Level Targeted Editing
Targets and edits individual neurons to perform fine-grained concept unlearning in foundation models, aiming for precise removal with minimal collateral impact on unrelated capabilities.
IEEE WETICE 2026
Towards Responsible AI: Concept-Level Steering in VLMs via Sparse Mechanistic Representations
Uses sparse, mechanistic representations to identify and steer specific concepts inside vision-language models — a step toward more controllable and interpretable multimodal systems.
Under Review, NeurIPS 2026
Counterfactual Feature Steering for Adjacency-Preserving Identity Unlearning
Applies counterfactual feature steering with sparse autoencoders to unlearn specific identities while preserving the surrounding representation structure of a model.
Startup — Valoi
Valoi Generative Video System
An AI-powered text-to-video system that converts educational text into videos for dyslexic learners — combining LLM-driven reasoning and scene planning with diffusion-based generative video into a unified, multi-scene pipeline. Underlies two U.S. patent applications.
IEEE ICMLA 2024
Segmentation of Maya Hieroglyphs through Fine-Tuned Foundation Models
Fine-tunes foundation models for pixel-level segmentation of Maya hieroglyphs, applying modern computer vision to a cultural heritage and archaeological documentation problem.
Research Output
Publications
Peer-reviewed and preprint work spanning machine unlearning, model steering, mechanistic interpretability, and computer vision.
