Meet the Authors

Our team of learning scientists, engineers, and product managers is focused on a comprehensive approach to creating effective learning environments for students. The research and development team has put forth a research agenda to study learning from a holistic perspective and continually advance learning science. With papers published at highly reputable scholarly conferences, they regularly share their research findings on a range of topics with the larger educational community.

Benny G. Johnson, PhD

Director, Research and Development

Benny G. Johnson, PhD, holds a bachelor of science in chemistry and mathematics from the University of Kentucky, and received his PhD in theoretical chemistry from Carnegie Mellon University, where he worked with a Nobel laureate. For the past fifteen years, Dr. Johnson has worked in the field of artificial intelligence for education, leading the research and development efforts of the Quantum technology for tutoring and assessment in chemistry, mathematics, accounting, and special education, and the machine learning predictive analytics technology of Acrobatiq, a Carnegie Mellon spin-off recently acquired by VitalSource Technologies. He leads VitalSource's research effort for using artificial intelligence to automatically create learning science-based courseware from textbooks at large scale. Dr. Johnson is the author of over fifty scholarly publications in academic journals and books and has delivered invited lectures at many national and international conferences. As principal investigator on various research and development projects, Dr. Johnson has received funding from the US Department of Education, National Science Foundation, National Institutes of Health, US Department of Energy, and Air Force Office of Scientific Research. He is a recipient of the Tibbetts Award, the highest recognition given by the federal government to small businesses for innovative research, and in 2007, he was inducted into the University of Kentucky's Alumni Hall of Fame. He enjoys playing music and lifting weights with his son.

Bill Jerome

Senior Product Manager, Research and Development

Bill Jerome is a computer scientist whose passion is connecting with the human user, developing easy-to-use systems capable of real good in the real world. His inspiration was sparked by virtual reality pioneer Jaron Lanier, who taught him the respect for his medium by telling him, “Real artists don’t love their tools—they strive to push their tools further and further so they can get closer to their artistic vision. Don’t be in love with your tools.”

Bill joined the Open Learning Initiative in its earliest days and is considered a founding member. More than a decade in the world of online education enabled him to creatively apply changing technology to real and dramatic needs, and in turn, push that technology to meet the needs of the application. He loves improving the experiences of learning to better answer education’s questions in a meaningful and directed way and is exhilarated by running into unexplored areas of computing accompanied by smart, talented people.

Favorite Professor: Dr. Klaus Sutner was Bill’s first professor of a computer science course at Carnegie Mellon University—an amazing, eye-opening, and career-defining experience. Bill and Dr. Sutner still find ways to work together.

Favorite way to spend free time: Bill enjoys hiking and camping, but when weather forces him indoors, he also enjoys watching movies and listening to music. He shares these loves with his child, imparting an affection for the finer points of film, such as an appreciation for the original Star Wars movies and a healthy skepticism about the prequels.
