Jenna Mandis :: jmandis@sileducation.com
Instructor of Science
Jenna is a native of San Francisco proper, and today calls Palo Alto home. Jenna graduated from San Francisco State University with a B.S. in Plant Ecology, and is presently pursuing an M.S. in Entomology at San Jose State University. As part of her graduate research, Jenna studies agricultural pests as they affect crop yields.
Jenna speaks with incredible enthusiasm about teaching and learning science, and believes that science is best learned by doing. Toward this end, nearly every day, Jenna and her students conduct colorful laboratory and field experiments that inspire the entire school to gather in awe. In this way, she is inadvertently instrumental in our community-building efforts at SIL. On Jenna's long list of favorite science experiments: lighting butane bubbles with sparks from a Van der Graaf Generator, destroying pennies in various ways (of note: a fresnel lens, liquid nitrogen, hydrochloric acid), and fashioning rockets out of plastic bottles and dry ice.
When she's not teaching or lighting things on fire, Jenna loves to run, hike, and care for her two pet chickens, which her students named Kevin and Waffles.

Stephanie Louris :: slouris@sileducation.com
Instructor of Science
Stephanie Louris holds a PhD in Materials Science and Engineering from Stanford University, and a B.S. in Chemistry from MIT. She began her career as a thin-films engineer in Paris, where she worked and traveled for six years. Back in the United States, Stephanie continued her work in materials engineering for several flat-panel display companies. She stayed at home to raise two boys, and then decided to embark on a new career direction: teaching science, something she had been thinking about doing for many years.
Stephanie greatly enjoys SIL's flexible and creative approach to teaching, as well as the opportunity to get to know her students by working one-on-one with them. When she isn't teaching, Stephanie enjoys movies, classical music, reading, and doing fun science activities with her boys.
