LLM Package Hallucination Analysis

This work investigates software supply-chain risk created by hallucinated dependencies in code-generating LLM outputs. It combines large-scale measurement with actionable insights to reduce package-level attack surface in developer workflows.

Prompt Refinement for Image Regeneration

This research examines how people infer prompts from AI-generated art, how contextual circumstances influence inference quality, and how iterative human-driven prompt refinement affects regeneration outcomes. Through human-subject studies and controlled regeneration tasks, it identifies when prompt inference is reliable, where it fails, and how structured refinement workflows can improve quality, intent alignment, and user control.

EtherBee

EtherBee constructs a global Ethereum dataset that combines node performance measurements, honeypot interactions, and full network-session traces to support reproducible security analysis of P2P blockchain infrastructure. Building on this data, the project provides initial evidence of elevated reconnaissance activity against overlay-network nodes and characterizes attacker scanning behavior across the ecosystem.

Spiking Neural Networks in Federated Learning

This project studies the performance and efficiency trade-offs of spiking neural networks in vertical federated learning settings. It characterizes where SNN-based approaches are beneficial and where practical deployment constraints remain.

VR Avatar De-anonymization

This project explores how non-VR motion side channels can undermine avatar anonymity in immersive environments. It highlights privacy risks in embodied interaction pipelines and motivates stronger identity-protection mechanisms.

Figure for AI Politicians

AI Politicians

AI Politicians is a platform that builds fine-tuned language models to simulate political communication styles, policy positions, and debate behavior. The system combines parameter-efficient LoRA adaptation with retrieval-augmented generation to support factual, context-aware dialogue and structured one-on-one or moderated interactions.
