Female academics are much more affected by the birth of a child than are male academics.

Academic mothers are much more likely to...

◾temporarily leave the labor force

Harvard today, your institution tomorrow.

New preprint with @jbakcoleman.bsky.social @lewan.bsky.social @randomwalker.bsky.social @orbenamy.bsky.social @lfoswaldo.bsky.social where we argue for a complex-system perspective to understand the causal effects of social media on society and for a triangulation of methods

The worst happened. We were DOGE’d. Our NSF funding is gone.

So now there’s nothing stopping me from sharing Expert Voices Together, a crisis response system for US-based researchers and journalists facing harassment.
