Xiaolong Luo

Ph.D. Student in Engineering Science at Harvard University

Welcome to my homepage! I am a Ph.D. student in Engineering Science at Harvard School of Engineering and Applied Sciences advised by Prof. Michael Lingzhi Li. Prior to that, I obtained my Bachelor’s degree in Statistics from the University of Science and Technology of China (USTC) advised by Prof. Yanran Wang and worked with Prof. Atlas Wang, where I was awarded the 41st Guo Moruo Scholarship, the highest honor for USTC undergraduates.

My research focuses on developing the foundations of next-generation artificial intelligence techniques to enhance its effectiveness and practical applications in healthcare. I am particularly interested in developing flexible diagnostic models with multi-task and multi-modal learning, aiming to improve medical assessments through the integration of various types of medical data.

You can reach me via email at xiaolongluo@g.harvard.edu. 🤝 I am actively seeking collaborations in healthcare-related domains! If you’re interested in AI applications in healthcare, medical imaging, clinical data analysis, or any related fields, feel free to reach out!

📋 Note: I am currently looking for summer 2026 internships! If you know of any suitable positions, I’d love your recommendations. Also always happy to chat over coffee!

🔬 Research Interests

  • Flexible Diagnostic Models with Multi-task and Multi-modal Learning: I work on developing advanced AI models that can simultaneously handle multiple diagnostic tasks while effectively integrating various types of medical data (imaging, clinical notes, lab results) to provide more comprehensive and accurate medical assessments.

  • Democratizing Healthcare Access through AI Agents: I am dedicated to developing intelligent healthcare agents that make medical resources and consultations more accessible and convenient for everyone. This includes creating AI systems that can provide preliminary medical advice, assist in resource allocation, and bridge the gap between patients and healthcare providers.

Working Projects

  • Healthcare AI Safety and Reliability Research
    Working with the CRITICAL dataset on exciting healthcare applications. Also exploring LLM reasoning traces and addressing a fundamental challenge: when AI models are used in healthcare applications, either through single LLM calls or an agentic system, there is a strong need to fully understand when and how AI models fail, and how to fix those issues to prevent catastrophic consequences.
