Undeniably, admissions committees prioritize a few select factors in considering applicants for scientific PhD programs. Foremost among them are previous research experience, matching interests with research groups, and undergraduate coursework. After three years of undergraduate research, I have received my fair share of advice on positioning myself for graduate school from colleagues, advisers, and friends. I would like to take a moment to articulate some of the most important insights, some of which I heard from others, but more often I had to find out for myself.
