How do PhD admission officers think about an undergraduate who worked in two research labs simultaneously?
I am currently a rising sophomore who started in a genetics lab in March. I found a really interesting opportunity to work in a biomedical engineering lab, and their position description requires me to learn many software skills which will be helpful for my bioinformatics track.
Assuming I can handle the workload, would adding a second lab strengthen my PhD application? Or might it raise concerns about my ability to commit deeply to one research lab?

I hope you’re doing well!
I’m currently applying to MD-PhD programs and have worked in multiple labs over the years, so I really resonate with your question. The short answer is:
It depends on
Quantity,
Quality,
and Consistency.
Here’s how I would break it down:
Quantity:
Yes, working in two labs can be a strong asset, especially if you can manage the workload. It shows you’re capable of balancing multiple responsibilities and that you’re serious about exploring research from different angles. But it only adds value if it doesn’t come at the expense of depth.
Quality:
If you’re planning to apply to a PhD program in genetics, I recommend prioritizing the lab most aligned with that field. Admissions committees care more about what you did than how many hours you logged.
Ask yourself:
What did I contribute to this lab that made a difference?
What skills did I gain?
Did I show initiative — like helping write an SOP, mastering a technique, or contributing to a project or publication?
Even if you spend over 1,000 hours in a lab, if you can’t articulate how you grew or helped the lab grow, the experience won’t carry as much weight. It’s not about the number. It’s about the narrative you can tell.
Consistency:
One thing admissions committees do watch for is how long you stay in your research roles. Jumping between labs every couple of months can raise red flags. If you do take on both labs, try to stay in them for a meaningful amount of time.
Read your labs’ recent papers, offer to assist on new ones, and if you can — stay long enough to see a project through. That kind of investment shows maturity and genuine interest.
The bottom line is:
If you truly believe both labs will help you grow — in different but complementary ways — go for it. Just make sure you’re not spreading yourself too thin, and that you're able to speak meaningfully about what you’ve done in each space.
You’ve got this! I’m happy to help if you want to talk through anything else — or if you’d like feedback on future decisions or applications.
Below are some steps I wish I had done (or done earlier!) during my own research journey:

At the same time, admissions officers appreciate seeing that you can commit deeply to your research and contribute significantly, rather than just spreading yourself too thin. So it’s important to demonstrate real involvement and growth in both labs, not just superficial participation. If both opportunities are meaningful, you can highlight them in your application and explain how their complementary nature adds value, while also emphasizing your commitment and ability to balance responsibilities.
Since perspectives can vary by program and faculty, talking with your current mentors, academic advisors, or faculty members involved in PhD admissions can provide tailored guidance based on your goals and workload. Reviewing the expectations of programs you’re interested in can also help you balance breadth and depth in your research experience. Best of luck!

Adding a second lab can really boost your PhD application. It can help you gain new technical skills and experience in different fields, especially if it ties into bioinformatics. Admissions committees look for candidates who show curiosity, initiative, and a range of skills. If you can explain how each lab has contributed to your learning—like how genetics gave you a strong foundation and biomedical engineering improved your computational skills—you'll be telling a compelling story.
Remember, depth is important too. Committees want to see that you can make meaningful contributions and stay committed to projects. If you switch labs too often or take on too much, it might raise concerns unless you can clearly show how each experience fits into your overall plan.
Here's a possible plan:
- Stay with the genetics lab to keep a consistent track record.
- Join the second lab, even if it's only part-time or during the summer, and focus on the specific skills you're gaining.
- When applying, highlight how these experiences work together and support your long-term research goals.
