Marshall Brain

Director
MS (1986), NC State University
Brain serves as part of NC State’s Entrepreneurship Initiative team and has been director of the Engineering Entrepreneurs Program since 2012. He coordinates the teaching, resources and support that enable students to develop working prototypes and business plans for their innovations.
He is most widely known as the founder of HowStuffWorks.com, an award-winning website that offers clear, objective and easy-to-understand explanations of how the world around us actually works. The site, which he created as a hobby in 1998 and took through several rounds of venture funding totaling approximately $8 million, was purchased for $250 million by Discovery Communications in 2007.
Brain has been featured on everything from CNN and Good Morning Americato The Oprah Winfrey Show. In 2008 and 2009, he was the host of the National Geographic channel’s Factory Floor With Marshall Brain, a series of one-hour factory tours taking the viewer on a journey into the world of product design, engineering and manufacturing.
Brain is the author of more than a dozen books as well as a number of widely known Web publications including How to Make a Million Dollars, Robotic Nation, Manna, and The Teenager’s Guide to the Real World. He frequently works with students at all levels to help them understand science and technology topics, entrepreneurship and how the world works.
He holds an MS in computer science from NC State and was named a Distinguished Engineering Alumnus in 2011.
