The 3 hardest things to learn as a scientist: 1. Trust the data.. especially when it’s not what you expected, 2. Trust the data.. allowing it to change your direction, 3. Trust the data.. but not too much: test with new data at every turn.

Researchers working on model organisms don’t do it for funzies. It’s because the questions they ask are important and can’t be solved using mouse, or human cell culture systems. Notice: This message is especially intended for journal editors.

When postdocs and grad students move on, I don’t worry about “losing” projects. If a postdoc wants to extend their work beyond my lab, my answer is yes. They should take their momentum with them. I have plenty of ideas, and there will always be more questions to ask.

Great advice received as a postdoc: Do the easiest thing. I was 3 years into my postdoc and juggling projects w/nothing concrete = career crisis I went to my advisor Paul Sternberg for help. He asked what was going on & what mutant had the strongest phenotype. "Clone the easiest one." It worked.
