Our editorial advice · not employer requirements

How to prepare a stronger application

Read about a laboratory's current research before explaining your interest. Connect a course, experiment, or coding exercise to a specific question you want to investigate. You do not need to pretend your class project was professional research.

Give potential recommenders time and context: your resume, why the lab work interests you, the deadline, and a reminder of work they supervised. Track the letters separately from your own application submission.
