The focus is on writing code that is easy to maintain and share with others. Students will develop these skills through a series of programming assignments and a group project.
APC 599 Summer Extramural Research Project A summer research project, designed in conjunction with the student's advisor, APC, and an industrial, NGO, or government sponsor, that will provide practical experience relevant to the student's research area. Start date no earlier than June 1; end date no later than Labor Day. A final paper and sponsor evaluation is required.
