Chengjie Lin

Machine Learning Engineer Intern @Optosurgical

Columbia, MD, US

I am contributing to the design and prototyping of an AI-driven surgical video analysis platform that will:• Track Procedural Progress by automatically identifying and timestamping completed operative steps.• Generate Real-Time Summaries of the current action in clear, concise natural language.• Forecast Upcoming Tasks through predictive modeling of the next likely procedural move.• Issue Early Warnings by detecting anomalous patterns or potential hazards before they manifest.Key Responsibilities:• Select and fine-tune a foundational vision-language model to the surgical domain, establishing clear success metrics for step recognition, next-step prediction, and hazard detection.• Architect scalable data ingestion and preprocessing workflows for continuous frame sequences.• Develop and maintain evaluation frameworks to benchmark step-recognition accuracy, prediction precision, and system latency.• Present weekly demos and technical reports to cross-functional teams, iterating on user feedback and performance data.
