Our personalized sleep guidance algorithm will be officially integrated into all Galaxy Watches. Thanks to Samsung, our math-based algorithm can help people sleep better and live healthier. From equations to everyday life—this is why we do research. #Sleep #GalaxyWatch #Math

Honored to speak on behalf of the scientific community. Grateful to President Lee for listening directly to researchers, just one month into office. A short talk—but a big step toward building a healthier research ecosystem.

Problem: Popular clustering methods (e.g., Leiden) give different results depending on random seeds. Our solution: scICE – a scalable and 30x faster algorithm to find consistent clustering outcomes, even in large datasets (10,000+ cells)!.

How do clock proteins behave in the brain’s circadian center? Using live imaging in knock-in mice, Smyllie eshow that PER2 and CRY1 act independently, not as one unit. Their stability, localization, and timing reshape our understanding of the SCN clock.

How do cells reliably flip gene switches in noisy environments? .We show that combining three indirect repression mechanisms—sequestration, blocking, and displacement—enables ultrasensitive & noise-resistant transcription.

“One Experiment Is All It Takes”: KAIST Team Revolutionizes Drug Interaction Testing, Replacing 60,000 Studies​.

Remember this plot from textbooks? Used in 60,000+ papers to estimate inhibition constants via multiple-dose experiments. We find most of those data are unnecessary—and even harmful. With just ~10% of data + a Cheng-Prusoff prior, we get better ones.

This will be presented at #SLEEP2025.

Tired of one-size-fits-all sleep advice?.Our app SleepWake uses real-time physiology-based modeling to personalize sleep schedules—and it works. Improved alertness, better alignment, real-world impact. Read the study: #Sleep #Circadian #DigitalHealth

New PNAS study finds that the optimal sleep duration varies by culture. It’s not how long you sleep, but how well your sleep matches cultural norms that predicts better health. Sleep is not one-size-fits-all. #Sleep .
