Reaching out to a Principal Investigator
A principal investigator, or P.I., is a professor or researcher that runs the laboratory group that you want to apply to. They typically come up with projects, help manage the projects that their graduate students are working on, and recruit new graduate students to mentor.
Remember, when you are looking for a project to apply to, apply to the project/professor, not the university. Of course, location can and likely will play a factor in your choice of graduate school, but your interest in the project, the funding available for your project, and the potential for a relationship with your P.I. is much more important.
After you have researched P.I.s, read some papers, and decided on those who you are interested in working with, it is time to reach out. Most P.I.s that you will reach out to have very little time to check and respond to emails during their busy days, especially from people that they don't already know. In my experience, I would say that about 50% of P.I.s that you email will never reply, and 50% of those 50% that do reply won't have time/funding/interest in taking on another student. Don't be discouraged- reach out to any P.I. that you can imagine yourself collaborating on a project with!
The cold email, or the email that you use to initially reach out to a P.I., should be concise, informative, and polite. You want to use their limited time available to read your email to let them know who you are and why you are contacting them. I use a template two paragraphs long to inform the P.I. that I'm emailing. Here is an example that I have used dozens of times:
"Hello there, Dr. Duffy!
My name is Gracie, and I’m currently a post-undergraduate research fellow for viral ecology and evolution at the Centers for Disease Control in Atlanta, GA. In May of 2022, I graduated from the University of Illinois at Chicago with B.S.’s in Biological Sciences and Earth/Environmental Sciences, performing research on antibiotic resistant gene evolution in natural and manmade environments. Currently, I perform various genetic and immunological tests to aid in the surveillance of poxviruses (such as monkeypox) and rabies, as well as participating in animal studies with rodents to understand pathology. As I begin looking for graduate programs for fall 2024, I’ve been eyeing marine disease laboratories, and I’m so happy that yours came across my radar. The combination of virology, conservation, and One Health practices that your laboratory uses caught my eye and fall both into my current skill set and future career interests.
If you have the time, I would love to have a Zoom chat with you about your laboratory (balance of laboratory, field, or animal work?), future open graduate positions (funding?), and what kind of skill set you look for in incoming researchers (PCR? ELISA? Animal handling? Field skills?). While I would not begin the PhD application process until this upcoming fall, I am putting out my feelers to potential labs to apply to, and chatting with you is at the top of my list.
Thanks for your time, and I look forward to hearing from you!"
After your sign-off, make sure to attach a copy of your C.V./resume to the email. This will allow the P.I. to take a glimpse at your background and see how well of a fit you may be for their laboratory group.
