A science educator for seventeen years, Tammy has taught elementary and middle school science and has mentored and coached novice science teachers through programs such as Peninsula Bridge, Breakthrough San Francisco, and the Exploratorium’s Teacher Induction Program. She earned her biology degree at the University of California, Santa Cruz, and her master's degree in science education at Teachers College, Columbia University. A National Board Certified Teacher in Early Adolescent Science, she is passionate about crafting learning opportunities for all students that ignite a love of science. And is she dedicated to finding the best ways to support STEM teachers in creating classrooms that do just that.

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.

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.

Michelle's love of STEM learning and teaching goes back decades. With her biology degree, she conducted marine mammal research, which led to a position as a naturalist teaching informal science education. Having seen the light and understanding the potential of this form of learning for reaching nontraditional learners, she returned to graduate school to deepen her understanding. Having taught middle school math and science for four years, she returned to Stanford for her doctoral degree in Science Education and taught Science Curriculum and Instruction to pre-service teachers in the process. For 18 years, she has worked as a researcher and evaluator in STEM education, first at SRI International, then the Center for Informal Learning and Schools at Exploratorium, and as an independent contractor with Inverness Research and her own research and evaluation group. She is thrilled to work with the many talented teachers and teacher leaders who are part of the Teacher Institute.

A Southern California native, Desiré earned an AS from Antelope Valley College, a BS in chemical engineering from UCLA, and an MS and PhD in chemical and material physics from UC Irvine. Her research focused on developing very fast laser and microscope systems that could capture molecules vibrating and rotating in real time. She was a postdoc at UC Berkeley, where she designed and built attosecond lasers (the fastest laser pulses, which emit x-ray light, ever measured). At the Lawrence Hall of Science she wrote an all-digital K–8 science curriculum (Amplify Science), which aligned to the NGSS, with the Learning Design Group (LDG). Desiré left LDG to teach hands-on laser technology and physics courses at Irvine Valley College before joining the TI staff. She is the proud mom of Stella, a four-year-old boxer-pit mix. In her spare time, Desiré is restoring her 1967 VW bug.

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 simple and accessible ways for all people to engage in science.

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.
