Rob Semper, Executive Associate Director and Director of Programs
Rob Semper is Executive Associate Director of the Exploratorium in San Francisco. He oversees the direction and content of the Exploratorium at Pier 15. Since joining the Exploratorium in 1977, he has lead numerous exhibit development, teacher enhancement and media development projects focused on science education for the public, teachers and students. He is also the principal investigator on numerous science education, media and research projects including the National Science Foundation (NSF) sponsored Center for Informal Learning and Schools, a research collaboration between the Exploratorium, U.C. Santa Cruz and King’s College in London which studied the relationship between museums and formal education, and the NSF funded Nanoscale Informal Science Education Network, a national network of science centers designed to foster engagement of the public with the nanotechnology field.
Over the past eighteen years Dr. Semper has guided the development of the award winning Exploratorium Website, which has explored the role of museums in the online world, including the development of online field trips to locations of scientific research. He has been a Schumann fellow at the Harvard Graduate School of Education and director of the creative collaboration between Apple Computer and Lucasfilm Ltd. formed to develop interactive multimedia education projects. Dr. Semper received his Ph.D in solid state physics from Johns Hopkins University in 1973.
Thomas Rockwell, Director of Exhibits and Associate Director for Program
Tom Rockwell leads the group that is responsible for the exhibit experience at the museum. He oversees a staff of approximately 65 people, including exhibit developers, science and art content experts, and a visitor research and evaluation team. Tom has been principal investigator for the Geometry Playground exhibition, and co-principal investigator for the Science in the Stacks project for the Queens Borough Public Library. With Rob Semper, he has also been deeply involved in the design and planning for the Exploratorium’s move to San Francisco’s Embarcadero.
Training in the visual arts at Brown University and a lifelong interest in combining art and science led Tom to work first as an educator in science museums, and then as a designer and construction coordinator of community-built science parks and playgrounds. These projects, in which thousands of volunteers collaborated to build a public structure, have had a strong influence on how he thinks about design, the creative process, and the public’s desire to engage in science. In 1995, Tom founded Painted Universe, Inc. Projects have included traveling exhibitions such as It’s a Nano World (with the Ithaca Science Center and Cornell University), The Enchanted Museum: Exploring the Science of Art (with the Berkshire Museum), and illustrations for The Elegant Universe by Brian Green. (NOTE: Tom is Norman Rockwell’s grandson.)
Silva Raker is founding Director of Exploratorium Global Studios and joined the museum as Director of Business Development in 2010.
Global Studios works with governments, universities, partner museums, libraries, hospitals and other public/private entities around the world to create learning environments and build human capacity – Exploratorium exhibits are one part of that effort. Raker’s work leverages the Exploratorium’s educational research and development to extend its mission. She extends the impact of the Exploratorium through museum consultancy, exhibit services, licensing, retail stores, restaurant concession, event rentals, sponsorships, and more.
Raker is an accomplished business development executive and has successfully grown vibrant, mission-based companies in the specialty retail and travel industries. Additionally, Silva is a trained scientist with a Bachelor’s degree in zoology from the University of California, Berkeley.
After conducting field studies in zoology in California and Cameroon, Silva joined The Nature Company where she spent ten years developing proprietary products, innovative programs and fruitful partnerships. More recently, as the COO and leading strategist for Backroads, Silva managed a complex global operation while developing both new and existing business segments—including the Family Travel Program with natural history and cultural exploration for kids on five continents.
