Lydia Bourouiba, Applied Mathematician

Watch how Bourouiba designs tests—some inescapably humorous and awkward—to study infectious disease transmission.

More about this episode

Bacteria and viruses hitch a ride inside droplets of all kinds—sneezes, raindrops, toilet splatter. By reviewing footage of different types of drops, applied mathematician Lydia Bourouiba records and measures where they disperse in order to better understand how diseases spread. Watch how Bourouiba designs tests—some inescapably humorous and awkward—to study infectious disease transmission.
