Paul Doherty graduated from the Massachusetts Institute of Technology with a PhD in physics. He was a tenured professor of physics for twelve years at Oakland University, Michigan, where he taught courses ranging from physics, astronomy, and geology to electronics, computer programming, and meteorology. In 1986 he came to the Exploratorium Teacher Institute, where he developed and taught workshops and published them on his web page. He was the author of many books, including the Explorabook, The Exploratorium Science Snackbook, the Klutz Book of Magnetic Magic, Color of Nature, and Traces of Time. Paul received the Faraday Science Communicator award from the NSTA and was named the “Best Science Demonstrator” at the World Congress of Museums in Helsinki in 1996. He played music on the whirly—a corrugated plastic tube.  He was also a rock climber and climbed the face of El Capitan, as well as making the first ascent of a 20,000-foot peak in the Sierra Nevada de Lagunas Bravas in the Andes.

Kristal is the project manager for the Teacher Institute and the Institute for Inquiry. She works across departments to plan workshops and events and to manage statewide professional development programs. Before arriving at the Exploratorium, Kristal worked as a park ranger, environmental researcher, sound designer, stage manager, and production assistant. She has a BA in communications and an MA in geography. Her other interests include music, books, rock climbing, gardening, and dogs, including her two rescue pups Gromit and Manny.

Zeke is a teacher in the Exploratorium’s Teacher Institute. Along with Tammy, Zeke’s primary role is to train and support coaches and mentors who work with novice science teachers in their first two years in the classroom. Zeke taught high school science for 21 years in Houston, Dallas, New Orleans, and San Francisco. He believes that science education starts when students construct their own understanding of the world.

In 2011, he was selected to be an Albert Einstein Distinguished Educator Fellow at the National Science Foundation. During his time there he worked with Congress and the White House on important science education issues, including writing a white paper on using large datasets in the classroom. In addition, he has worked as a science advisor for both NBC Learn and Discovery Digital. For fun, Zeke puts on physics circus shows. He thinks of them as magic shows, but in reverse—the secret to a magic trick is to make something simple intentionally confusing, while Zeke tries to make confusing things easy to understand.

Staff teacher Lori Lambertson was born and raised in California and has a lifelong interest in and love for this area. Lori studied biology and dance at the University of California, Santa Cruz, where she also had a brief but thrilling career as a professional bicycle racer. She completed a BFA with an emphasis in painting at the University of San Francisco, and an MA in education from San Francisco State University, where she also earned her teaching credentials. Lori taught both math and science at the middle school level. She attended the Summer Institute in 1991, which was a life-changing experience. In 1996, she left classroom teaching to work as a Teacher-in-Residence in the Exploratorium’s Teacher Institute (TI). Lori co-authored The Math Explorer, and has had teaching experiences in India and Costa Rica and throughout the United States. She enjoys hula dancing, learning Spanish, painting, gardening, cooking, hiking, and surfing.

Eric began his career as a geologist, wandering remote dirt roads in the American Southwest. After a few years, he decided to get his hands dirty and became a credentialed teacher. He taught chemistry, physics, geology, math, and at-risk-youth programming in Bay Area public schools. After attending his first Summer Institute at the Exploratorium, he was hooked! He joined the Teacher Institute in 1995 as a science, math, and technology educator.

Eric has created numerous hands-on activities and conducted professional development workshops from Alaska to Costa Rica, China, and Tobago. He has written articles for The Science Teacher, The Physics Teacher, several museum publications, and various websites. He is the author of While You’re Waiting for the Food to Come, a book of science activities that can be done at restaurants. He has also been a contributor to NPR and helped to create an internationally distributed poster of the Earth’s Anatomy.

Eric earned a BS in earth science from the University of California, Santa Cruz, and an MA in education from Columbia University. He was a fellow at Tufts University’s Wright Center for Innovation in science education. He has also worked as a whitewater rafting guide, done research on glaciers, worked in a high-energy physics lab, and taught courses at several universities.

Bay Area native Hilleary Osheroff is the Teacher Institute’s Staff Biologist and resident expert in carbon-based life forms. She holds a PhD in neurobiology and developmental biology from the Rockefeller University. Before joining the Exploratorium, she taught high school students at the American Museum of Natural History in New York City, where she learned a lot about evolution and phylogenetics; worked with paleontologists, conservation biologists, and anthropologists to provide research experiences for students; and was generally swept off her feet by teaching science in museums.

Her favorite things in San Francisco include the Bernal Hill hawks, Ocean Beach, sea lions, dumplings on Balboa, burritos on Mission, and her two small children.

Don has taught physics for over fifty years—“since the crust cooled,” as he's been known to say—in settings ranging from a college in Liberia and a high school in Turkey to public high schools in Pleasanton, California. He was a participant in the Teacher Institute’s first Summer Institute in 1984. He has been working with science teachers at the Exploratorium since 1985, and co-authored (with Paul Doherty) the Exploratorium Science Snackbook, first published in 1991. The Snackbook shows teachers how to use simple materials to build classroom versions of over 100 Exploratorium exhibits. He also co-authored (again with Paul Doherty) Square Wheels, with thirty-one additional science snacks.

In 1983, Don began “Physics Day” at Great America, an amusement park in Santa Clara, California, an event that has grown from ninety students to more than 20,000. Continuing his lifelong interest in toys, he was the author of Lego Crazy Action Contraptions. More recently, one of his grandkids worked as a volunteer and intern for three years TI Summer Institute.

Don received a BS in Engineering from Stanford University and an MA in Science Education from Columbia University. He and his wife, Ann, live in Pleasanton, California.

Daisy is TI's newest Teacher-in-Residence. She participated in the New Teacher Institute at the Exploratorium during her first years in the profession, and attributes many of her favorite teaching moments to what she learned through TI's inspirational workshops and from staff. She first experienced the excitement and challenge of working with students when volunteering after school in Oakland’s Chinatown. After working as an exhibit facilitator at the Lawrence Hall of Science and surviving a year of substitute teaching, she was ready to officially join the teaching profession. She received her BA in molecular and cell biology from UC Berkeley and an MA and teaching credential from Stanford University, then began working at Woodside High School. After nine years of teaching biology and earth science to some amazing freshmen and sophomores, she decided to try something new and applied to work at the Exploratorium (because who doesn't want to work here?). She hopes to bring in her experiences fresh out of the classroom to TI to help other teachers address the diverse needs of all of their students.

Daisy and her husband recently celebrated their marriage at a campsite along the south coast of Iceland. They currently live in San Francisco and enjoy bringing their Scottish terrier, Olive, to enjoy the outdoors as often as possible. One of their favorite trips was bringing Olive on a summer road trip through the western United States, where she learned to be an excellent crag dog and hiking companion.

Julie first participated in the Institute as a middle school math and science teacher, then went on to graduate school, earning a PhD in chemical engineering with a minor in molecular and cell biology from the University of California, Berkeley. In 2006, after completing her research in viruses, stem cells, and how to win at foosball, Julie returned to the Exploratorium and discovered an ideal blend of science, education, and play. Julie’s passion is creating hands-on activities that demonstrate real science with the simplest materials possible.

In her spare time, she still thinks about science, but usually in the kitchen, where she can focus on her favorite synthesis of physics, chemistry, and biology—cooking and eating.
