When Kaveh Madani returned to Iran last September to serve as his country’s deputy vice president for the environment, political hardliners didn’t exactly lay out a welcome mat. Upon his arrival in Tehran, the water management expert was detained and interrogated, and several years’ worth of his photos and emails were confiscated.

Eventually, things settled down and Madani, 36, a specialist on Iran’s dwindling water resources, started to raise his profile inside the country. Prior to his homecoming, he had been a faculty member at Imperial College London and spent 14 years overseas, including 3 years at the University of Central Florida in Orlando.
