You probably already know this, but today was the first full missed pay check for most of your friends, colleagues, POs and SROs at the NIH.

Stay strong out there folks. If you need help, ask for it. As always, try to be kind.

Excited to share this new work from the lab, in collaboration with @jtuscher.bsky.social & Rob Sorge! Here, we used single cell transcriptional profiling to define molecular adaptations induced by chronic pain and opioid experience, which often occur in conjunction.

I beg my science colleagues to speak with the media about what's happening now.

When I was given the opportunity, I spoke with Nature about HHMI massive cut. I am an immigrant on a working visa, and I am not a professor. Anyone can talk. Silence in the face of injustice is injustice in action.

I’m standing up for the next generation of diverse scientists. The rare disease patients. The cancer patients. The species that may never walk the planet again. Women’s healthcare.

This assault on science should not be acceptable to anyone, and it won't go away unless we make it go away.
