Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do when they freeze?

Water balloons may seem like a trivial matter. A toy for mischievous kids in summer. But for scientists, the behavior of balls of liquid wrapped in a thin elastic membrane is critical to everything from understanding blood cells to fighting fires.
Michael Webb has joined the Princeton faculty as an assistant professor of chemical and biological engineering, bringing expertise in modeling molecular interactions important to health and energy.
