For over a decade, Liesl led an extensive and nationally recognized partnership program at UCSF between biomedical scientists and San Francisco's public school teachers that was initiated by UCSF faculty members including Bruce Alberts, former President of the National Academy of Sciences; J. Micheal Bishop, UCSF Chancellor and Nobel Laureate; and Harold Varmus, former Director of the National Institutes of Health and Nobel Laureate. She has served as Principal Investigator or Co-Principal Investigator on major awards addressing professional development, partnership, and diversity issues from the National Science Foundation (NSF), the National Institutes of Health (NIH), the Howard Hughes Medical Institute (HHMI), the California Science Project, 3M, and the Medtronic Foundation.

Before her work in professional development, Liesl taught elementary school in SPPS, coordinated educational programs at the Science Museum of Minnesota and the Bell Museum of Natural History, and apprenticed under the late Todd apJones, noted hand-lettering artist. Proud alumna of the University of Minnesota, Liesl has a Bachelor of Science in Elementary Education and a Minor in Linguistics. Liesl is also an inveterate graphic journaler and has been visually chronicling science education reform since the early 1990's.

Travis Sandland
IDEAL Center Project Lead
Travis joined the professional development team in 2006, and is currently a Project Lead. Professionally, he is particularly interested in challenging and reconstructing the beliefs, attitudes, and values that undergird STEM and advantage some groups of students and ways of knowing over others in our educational systems and society at large.

Travis began his career at the SMM after graduating with honors from Macalester College with a Bachelor of Science in Geology and a Physics minor and earning his masters in Geological and Environmental Sciences from Stanford University. He was a Youth Program Manager in the Kitty Andersen Youth Science Center, the SMM youth development program, where he worked with youth traditionally underrepresented in STEM careers. At this time he was also the SMM Earthscapes Outreach Teacher and worked with researchers at the University of Minnesota's National Center for Earth Surface Dynamics to translate their work into experiences for students and teachers.

Travis has been a contributing author on multiple grants, and served as co-designer and facilitator for many programs for teachers and educational leaders: including PAGE, funded by the National Science Foundation and Nexus: A Statewide Professional Community for District-Level STEM Leaders funded by the Medtronic Foundation; and Science House and the SMM Educator Resource Center, funded by the 3M Foundation.
