Microscopic Marvels: Cells That Defy the Odds

Imagine an embryo as a tiny, powerful builder, starting from just one cell and forming an entire body with billions of cells. Remarkably, early mouse embryos can lose 85% of their cells and still build a full body in just five days! My research studies how this boosted growth works. Join me to explore this fascinating regeneration process and its potential applications for therapies.

Some tiny single-celled organisms move at jaw-dropping speeds—outpacing much larger animals! How do they survive extreme forces and fuel their motion? Using cutting-edge imaging and simulations, I uncovered a universal speed limit, a unique cellular shock absorber, and the energy secrets of a parasite—insights that could spark new bio-inspired technologies!

For the body to work properly, cells must know how to align with their neighbors. They do this by building distinct molecular clues at each end, which help them understand which way is up, down, left, and right. We are still not sure how this happens. In my research, I look at the direction of the hair on the wing of a fruit fly to see how all the hairs point toward the wing tip.
