Alok Jha is a self-described water obsessive, a scientist and communicator; he's made an art form of unpacking some of the most complex questions of our age. A fascination with water has taken him literally to the ends of the earth. A journey to Antarctica in 2013 came close to an unfortunate end. He joins a long list of remarkable science communicators, who try to make the incomprehensible sound simple. He and his wife recently had their first child, and somewhere in between all of this, he's penned the Water Book.
