WINS Has Built a Powerful Network of Women in Networking
Nine years after the Women in IT Networking at SC (WINS) program was first piloted in 2015 to increase gender diversity in the research and education community’s ranks of network and computer systems engineers, women remain a small minority in these skilled, well-paying careers. Just 9.4% of network engineers and 13.2% of computer systems engineers are women. This is why WINS has been both game-changing — and life-changing — for the 56 women who have participated. Read More
