<p>I need two recommendations for a lab internship. I am already getting one from my PI, but I'm wondering who I should ask for my second one. My PI has taught me in class and is aware of both my academic and research performance. I could ask another professor but I don't need another person to talk about academic performance as I am applying to a lab, not grad school.</p>
<p>Is it ok to ask a TA? Will their rec still be taken seriously? I want to ask my TA who teaches my lab course. We learn techniques much different from what I normally do in my own research lab so if he spoke of those skills, I would seem more well-rounded in the lab. In addition, he has worked in the lab I am applying to. </p>
