Michaela Cavallaro has spent her career figuring out how things work, then sharing what she's learned. Over the last 20 years, she's untangled the deregulation of the electric grid, explained the interconnection of artificial intelligence and the stock market, demystified chip cards, and learned more than any one person should know about the U.S. retirement system. Michaela lives in Maine with her teenage daughter and two small dogs, all of whom remain utterly inscrutable.
