Excited this is officially out! RNA fingerprinting interprets sc perturbation experiments using large reference datasets, accounting for baseline heterogeneity, perturbation strength, outliers and correlation structure. Fun collaboration with Satija lab led by fantastic postdoc Izzy Grabski.

Wow. "NIH" canceled my co-mentored (with Dave Sulzer) PhD student's F31 funding. His work is on understanding the genetics and neuroscience of language learning disorders. F31 provides no indirect $ to Columbia, just pays his salary. Not that it should matter, but he's an American citizen. W.T.F.

Thinking back on all this I better understand the pain I feel to see science under devastating attack here. It’s not just about my livelihood or my university. It’s about my identity. And it’s about a pursuit that I see as standing along with art, literature, and music as among our highest callings.
