How to Join a Research Lab as an Undergraduate and Strengthen Your Graduate School Applications

Why Undergraduate Research Matters

I've talked to a lot of students who treat lab experience like a checkbox -- something you do because it "looks good." That's the wrong way to think about it.

The real value is what you find out about yourself.

A friend of mine spent a semester convinced she wanted to go to med school. After six months in a neuroscience lab, she realized she loved the research side more than the clinical side. That one experience completely changed her path. She's now finishing a PhD.

Research gives you:

• Real letters of recommendation (a PI can speak to how you actually work, not just how you score on tests)

• Concrete material for your personal statement

• A test run for whether grad school or med school is actually right for you

• Skills that transfer anywhere: data analysis, problem-solving, scientific writing

When Should You Start?

Timing matters more than most students realize.

The short version: sophomore or junior year is the sweet spot. Freshman year is usually too soon -- you're still finding your footing academically. Junior year is ideal -- you've got foundational coursework done and potentially two full years to build something meaningful. Senior year is still worth it, mainly for the recommendation letter you'll get before applications go out.

Don't overlook summers. The National Science Foundation funds undergraduate research placements at universities across the country -- competitive, but they come with stipends and serious lab time. University-funded summer positions also exist. Applications often open in January, so check early.

How to Find a Lab

You don't have to wait for a position to be advertised. Most aren't.

• Browse your department's faculty pages and read what each lab actually works on

• Attend research seminars and poster sessions -- low-pressure ways to scope out labs

• Ask your TAs. If they're a grad student, their lab might be looking

• Talk to classmates already in labs -- they'll tell you which PIs actually invest in undergrads

Don't limit yourself to your home school. Professors at nearby universities sometimes take students too.

How to Apply

Most labs don't have a formal application. You just email the PI.

Keep the email short:

• Your name, year, and major

• 2-4 sentences on why their specific research interests you (not just "I love science")

• Attach a basic CV or resume -- even if it's mostly coursework

You don't need prior research experience. Faculty primarily look for motivation and reliability, not a polished skills list, as Kate Nussenbaum's research advice explains.

One student I know was so nervous to email a professor that she drafted the message for two weeks before sending it. The PI replied the same day and invited her in for a meeting. The hardest part really is just hitting send.

How to Prepare for an Interview

If the PI wants to meet, here's how to show up ready:

1. Read something from their lab -- a recent paper, a project description, anything. You don't need to understand it fully; you need to show you tried.

2. Know your availability. Expect around 10 hours a week if you're taking course credit.

3. Bring questions. Ask about mentorship structure, what undergrads typically work on, and how quickly you'd get hands-on time.

4. Bring your resume.

Be honest about your skill level. PIs know you're a student. What turns them off is overconfidence or unreliability -- not inexperience.

Does It Have to Be a Wet Lab?

No. This comes up constantly, and the answer is straightforward.

The AAMC is clear that all research disciplines count for medical school -- sociology, history, policy, biology, computational science. The field matters less than your level of engagement.

If bench work doesn't appeal to you, look at:

• Social science or psychology labs

• Computational or data-focused research

• Field research or public health projects

• Humanities research with a faculty mentor

Is Research Required for Med School?

Not technically. But the numbers tell a more nuanced story.

The AAMC reports that around 60% of incoming students had some form of lab research experience. A separate AAMC survey of admissions faculty ranked research as medium importance -- below community service, shadowing, and leadership.

So it helps, but it's not the deciding factor for most MD programs.

If you're applying to MD/PhD programs, that changes completely. Research experience there is effectively non-negotiable.

If you went to a small liberal arts college with limited lab access, admissions committees generally account for that. You won't be penalized for something your school didn't offer.

How Research Strengthens Grad Applications

Beyond med school, research is much more central to graduate program admissions.

Here's what it actually does for your application:

• A PI recommendation carries more weight than a course professor's letter. They can describe how you think, how you handle setbacks, and whether you show genuine intellectual curiosity.

• Your statement of purpose gets stronger when you can point to a real project, a real question you worked on, and what you learned from it.

• Presenting at a lab meeting or student conference shows you can communicate your work, not just do it.

• Emailing faculty at target programs before you apply puts your name in front of them early. Contacting a PI directly before submitting is encouraged by most programs.

Before You Commit

• Not every lab is a good learning environment. Ask other undergrads in the lab before you sign up.

• Early tasks will be boring -- data entry, moving equipment, prepping samples. That's normal. Push through it.

• Treat it like a job. Show up on time. Meet your deadlines. The fastest way to lose a good reference is to be unreliable.

• If a lab isn't working out, it's okay to move on. Finding a better fit is smarter than sticking with a bad one.

Start Now, Not Later

Start earlier than you think you need to, email more PIs than feels comfortable, and take the work seriously once you're in. The longer you're in a lab, the more valuable it becomes -- to your application and to you.
