Counterpoint to the above: I worked with Marlow for my whole PhD (2018–2023). The "low bandwidth" is real but it's how she trains people who go on to run their own labs. Two of my labmates from that cohort now have faculty positions.

It is not the right environment for someone who needs frequent direction. It is excellent for someone who wants to be left alone to figure out what kind of scientist they're going to be.
