Billy Hoy — PhD Student

I am a PhD student in Operations Research & Systems Engineering at the University of Miami, with an undergraduate background in Mechanical Engineering. I also work at the Center for Naval Analyses (CNA), the Navy’s federally funded research and development center, where I contribute to data driven research and operational analysis for defense applications.


Current Work

  • Continual learning methods for large language models
  • Reinforcement learning environments for complex optimization problems

Past Work and Publications

Evolution Strategies for LoRA Based Adaptation (Technical Blog Post, 2025)

A recent write up exploring how Evolution Strategies (ES) can be applied to LoRA adapters instead of full parameter fine tuning, reducing compute cost while enabling exploration-based optimization.
Blog Post: Evolution Strategies + LoRA

STABLE: Gated Continual Learning for Large Language Models (First Author, 2025)

Proposed a gated continual learning method for LLMs that applies LoRA based updates only when they meet stability criteria, reducing catastrophic forgetting while enabling efficient sequential adaptation.
Paper: arXiv

Medical Computer Vision Research (Second Author, 2024)

Developed YOLO based detection and segmentation models for surgical instrument tracking and designed temporal metrics for evaluating surgical skill.
Paper: ScienceDirect

Early Research Exploration (2024)

Hands on exploration of POMDPs and latent representation learning for decision making under uncertainty.

FAA Data Challenge – Finalist Project and Conference Paper (2023)

Built reinforcement learning models to optimize routing and decision making for eVTOL operations under uncertainty.
Paper: ACM Digital Library Project: FAA Data Challenge Finalists


Defense Work (Center for Naval Analyses)

  • Reinforcement Learning for Weapon Optimization: Built RL environments to model weapon effectiveness, engagement sequencing, and operational decision making under uncertainty.
  • Defense Modeling and Analytics: Conducted end to end modeling work including data engineering, feature development, statistical analysis, and predictive modeling for Navy datasets.
