Sometimes, the biggest discoveries have to do with the smallest things. In this case, we’re talking nano. Specifically, nanocrystals. World-renowned chemist Paul Alivisatos has changed the field of nanoscience with these tiny crystals, but he’s also found ways to use them to create incredible new technologies in healthcare, energy, and electronic devices.

As if that weren’t enough, Paul Alivisatos is also an eminent leader in academia. He was the Executive Vice Chancellor and Provost at the University of California, Berkley and is now the President of the University of Chicago. In that role, he hopes to implement his vision of an “engaged university” to push forward the role of academia in society.
