The study is framed by two questions:1. What contributed to the successful completion of a Science, Technology, Engineering, and Mathematics (STEM) Ph.D. by minority graduate students at the University of California between 1980 and 1990?2. Did their subsequent careers after the Ph.D. correspond to their training and aspirations? Answering these entailed learning about participants’ entire lives from birth to the present, and studying individuals of all ethnic groups to look for similarities and differences in background, experiences, educational path, and careers. 158 Ph.D.s were interviewed: 33 African Americans, 35 Asian Americans, 24 Chicanos, 13 Hispanics, 5 Native Americans, 52 European Americans. The latter were matched to minority students from the same lab, with the same advisor, and similar degree year. Interviews averaged between two and three hours and used a standard questionnaire.Funding: Spencer Foundation Major Grant Program, Grant No. 200000265 P.I.
