One day, I would love to edit a book with us all sharing anonymous short stories from faculty interview visits. Everyone except white men.

(This request brought to you by my faculty field tour w/dozens of new faculty, when the men were like WAIT WHAT HAPPENED AT YOUR INTERVIEW??)

Advice I now give to grad students and postdocs in the sciences: Don’t just try to meet and impress senior scientists. They’ll retire soon. Get to know your fellow students - make friends where possible, be colleagues at least. These are the people you’ll be sharing the field with for decades.

Why do males and females often differ in traits?
The expected answer: selection.
But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism β€” even when male & female optima are the same

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

I’ve flown there each of the last 3 summers - twice from the UK and once from the US. Every time I land I’m so excited to be in a country with decent infrastructure. And the birdsong is such a nice touch - so charming.
