Editor's notes
- You apply to one of nine BBS Tracks, and each Track has its own admissions committee, so pick the Track by its scientific focus and curriculum rather than by which faculty are listed. The 500–1,000-word statement should cover four things in order: why you do research, a detailed account of your research and how it prepares you, a concrete example of taking initiative, and your career goals; naming BBS faculty is allowed but optional. Immunology applicants also answer a 250-word hypothesis question. Plant Molecular Biology is the one Track that strongly encourages contacting faculty before applying.
