<p>^^I would guess chemistry, although I have seen one person with a BS and a PhD from there. My guess is if you are an established and productive member of a research group (like publish a 1st author paper) and do well in class, then you.</p>
<p>I don’t think Mikalye is right about chemE. I don’t think they discourage undergrads getting a PhD at MIT. It’s generally math/science depts. that do that, not engineering.</p>
