AI & machine learning research for health.

I’m based in Brooklyn and am a Visiting Professor at the University of Tartu, Institute of Computer Science. I do research & teach computer science courses on AI, machine learning, and data science.

Previously, I created the One Fact Foundation, a 501(c)(3) non-profit, to help scale the work I have done in large language models for health care use cases. We raised $300k+ to reduce the price of health care using open source, collected data from 4,000+ hospitals, got IRB approved to train models on health records, and published visualizations of tens of millions of hospital prices here.

For my Ph.D., I was fortunate to be advised by David Blei and Shivaji Sondhi. My work was supported by the Natural Sciences and Engineering Research Council of Canada I had fun working with Andriy Mnih at DeepMind, and Eugene Brevdo at Google Brain. Previously, I studied Maths and Physics at McGill and was an Officer of Research at Columbia University Irving Medical Center. Find my CV at jaan.io/cv.

I’m Estonian-Canadian and outside of academia I love volleyball, meditation, music production, and George Saunders.

How can we use technology such as machine learning and AI to effect the most societal good? This is what motivates me. A decade ago, I am proud to have launched Useful Science with a group of friends – I hope you’ll find a study on there that improves your life. One fact can be all it takes to create change.
