This grant funds a joint effort by Barnard College and Columbia University’s School of Engineering to prepare undergraduate women to succeed in an accelerated M.S. degree program in engineering. Selected students will complete a four-year undergraduate major at Barnard coupled with a one-year master’s degree at Columbia Engineering, for a “4+1” program. Students from racial and ethnic groups traditionally underrepresented in engineering will be a special target for recruitment into the program, particularly those from low-income families. Four cohorts of eight students each will receive support across their junior and senior years at Barnard and their master’s year at Columbia. Barnard and Columbia Engineering will build a comprehensive structure of support for students in the program, including direct faculty advising, well-delineated paths for academic courses beginning in the junior year, career counseling, cohort-level support, and financial aid to encourage participation and success. All students will be guaranteed support for summer research experiences for two years, research-based cohort activities, and intensive faculty advising. Nine diverse scholastic pathways have been identified through the program to date, including mapping a major in chemistry to an M.S. in chemical engineering, and opportunities for math, statistics, economics, computer science, or physics majors to earn one of five M.S. degrees in the Columbia Department of Industrial Engineering and Operations Research.
