On Sept. 25, the Harker Programming Club held its fifth annual Girls Programming League Challenge, with 130 girls and non-binary people from 65 schools participating. Contestants worked in teams to solve a series of Olympiad-style computer science problems written by officers from the Programming Club. In keeping with the event’s theme of computer science in medicine, the event also featured a keynote speech by Google Health software engineer Maria Nattestad; a panel discussion with Dr. Natalie Pageler, clinical professor of pediatric critical care and chief medical information officer at Stanford University; Johanna Kim, executive director of Stanford’s Center for Artificial Intelligence in Medicine and Imaging; Aleks Goeva, a researcher at the Broad Institute of MIT and Harvard; and upper school science department chair Anita Chetty.
