Part of the issue is that academics are too slow to explicitly call out one another's bullshit. There's a bit of a bystander effect, and when that happens, people who do call it out are more likely to be targeted through peer pressure or sometimes even lawsuits.

If you can't wake up on Monday, go for a five mile run, meditate, write an entire R01 before 8am when the sponsored research office starts work, and make latte art with hand-ground espresso, are you just too lazy for faculty life?

Mentoring junior scientists is the most meaningful and probably most important part of being a professor. I could not be more honored or flattered to be selected for this award

The biggest misconception of graduate school I see is that you are going to learn science directly from your professors. Even if you learn more from your PI than from any one other person, you will learn far more in aggregate from other trainees than any one professor.

I’ve heard a lot of “but what about the risks of a new vaccine tech” takes from usually reasonable people recently. My math is that over 35000 people have now been given an mRNA vaccine. If there were risks anywhere close to Covid’s we’d have seen it. It’s by far the safer option

The dangers of EtBr and radioactive reagents are far overstated. The dangers of Bunsen burners and razorblades are underappreciated

What is your most controversial lab opinion? I think a lot of stuff people keep in a -80 could probably be in a -20 and nothing would happen
