Bio:
Vivek Natarajan is a Research Scientist at Google leading research at the intersection of large language models (LLMs) and biomedicine. In particular, Vivek is the lead researcher behind Med-PaLM and Med-PaLM 2, which were the first AI systems to obtain passing and expert level scores on US Medical License exam questions respectively. Med-PaLM was recently published in Nature and has been featured in The Scientific American, Wall Street Journal, The Economist, STAT News, CNBC, Forbes, New Scientist among others. More recently, Vivek also led the development of Med-PaLM M, the first demonstration of a generalist biomedical AI system.
Over the years, Vivek’s research has been published in well-regarded journals and conferences like Nature, Nature Medicine, Nature Biomedical Engineering, JMLR, CVPR, ICCV and NeurIPS. It also forms the basis for several regulated medical device products under clinical trials at Google, including the NHS AI award winning breast cancer detection system Mammo Reader and the skin condition classification system DermAssist.
Prior to Google, Vivek worked on multimodal assistant systems at Facebook AI Research and published award winning research, was granted multiple patents and deployed AI models to products at scale with hundreds of millions of users.

Recent talks:
- Transformers in biomedicine Lecture talk - Feb 21, 2023
- Title - Transformers in biomedicine
- Summary - In recent years, the field of AI has been revolutionized by the emergence of Transformers and Large Language Models. However, perhaps nowhere is their impact more profound than in the biomedical domain, where they have the potential to drive human health and potential forward. In this talk, I will explore the ways in which these models are being adapted and applied to biomedical research, with a specific focus on the challenges and opportunities presented by data, modeling innovation, and evaluation. From medical question answering to gene sequencing correction and expression prediction, as well as the natural language annotation of proteins, these cutting-edge techniques are opening up exciting new possibilities for the advancement of medical science and healthcare. Finally, I will offer my insights on how the field of biomedical AI is likely to evolve in the years ahead, and how we can all contribute to this promising area of research.

- Title - Building Better Medical AI for Clinical Deployment at Scale
- Summary:
- In recent years, we have seen several research breakthroughs demonstrating the potential of AI in healthcare settings. However, we are yet to see AI have any impact in the real world and improve patient outcomes. In this discussion, I will lay out some of the key challenges of developing and deploying AI at scale in clinical settings and introduce some of my work done at Google towards addressing them. We will then have an open discussion on how we can accelerate the solving of these challenges and realize the potential of AI in clinical settings. Key takeaways
- *Why is AI yet to have real world patient impact? What are the key technical and non-technical challenges we need to address for this to happen?
- *How can we address those challenges systematically? I will be drawing upon examples from my work at Google to illustrate this
- *We have all the key ingredients to address these issues and if we can make systematic progress, we can very soon realize patient impact at scale with AI
