Women are making major gains in enrollment in engineering and computer science at some of the nation's most prominent colleges and universities. While men still far outnumber women nationally - 4 to 1 in engineering, 5 to 1 in computer science - female students are gaining ground slowly at many schools and rapidly at others. The federal government and industry leaders acknowledge that more should be done to bring women into science, technology, engineering and math, known as the STEM fields, and they have pushed programs such as Girls Who Code to boost interest among girls at a young age. Samantha Horry, 18, from the suburbs of Philadelphia, is one of 80 young women among 165 new computer science students this fall at Carnegie Mellon. She fell for the subject in high school, taking eight classes. Almost always, she was the only girl. Just me and some guys," she recalled. That didn't deter her from winning admission to one of the country's most prestigious programs to pursue her interests in machine learning and artificial intelligence. Now Horry is startled at how many young women on campus are following her path in a field where the stereotype of the male teenage computer geek, obsessed with gaming and programming, looms large. She looks around in class and sees, for the first time, gender balance. "It's crazy and awesome," Horry said. "I don't feel out of place."
