Dear Hannah, Thank you for your interest in working in my lab this semester. Your background in statistics would be very useful for our current project on sleep and memory. Before I can offer you the position, there are two things to take care of. First, all lab members must complete the university's online research ethics course. It takes about four hours, so please don't leave it until the last minute. Second, I'd like to meet with you briefly to discuss your schedule, since several of our experiments run in the evening. I'm available Thursday afternoon or Friday morning. Let me know which works better for you. Once the ethics certificate is on file, you can start right away. Best, Marcus Webb
