Work History

Software Engineer Intern - Generative AI

Shelton AI
09.2023 - Current
  • Integrated a file type conversion system into the existing codebase, allowing for greater platform capabilities and generative ai applications
  • Designing and building an information extraction tool for financial documents utilizing the new GPT-Vision API and Amazon's s3 bucket storage

Graduate LLM Researcher

RISE Lab
09.2023 - Current
  • Assessing the performances of various LLMs statistically with the heavy tailed self-regularization method and the WeightWatcher tool
  • Using GPU clusters to test correlation between LLM alpha values vs observed model performance through evaluation on large question-answer datasets with zero-shot vs few shot, explain prompting, fine-tuning methods, and LoRA training scenarios

Machine Learning Intern

Kaiser Permanente
05.2022 - 09.2022
  • Improved sentence embeddings of patient pre-hospital visit reason by migrating to a Sentence-BERT architecture which increased downstream predictive power by 10% and strengthened robustness
  • Fine-tuned a GPT-J model to extract kidney stone features (size,laterality,etc.) from chunks of radiology reports with 80% accuracy, overcoming annotated data shortages with Self Learning and Active Learning
