Massachusetts General Hospital, Lab of Medical Imaging and Computation

Intern (June 2022 – August 2022)

Developed high-accuracy PyTorch neural networks to classify X-ray images by body part, advancing lab research by visualizing model interpretability through heatmaps, ROC curves, and confusion matrices.


  • Developed neural networks with PyTorch to classify X-ray images based on corresponding body parts, achieving 99.3% accuracy rate
  • Contributed to research mission of lab by exploring techniques to present the importance of each image within model’s training dataset using visualizations such as heatmaps, ROC curves, and confusion matrices
  • Optimized and resolved hardware and software issues of high-performance servers used for research
