looking for collaborators in building an atlas / database of astrocyte heterogeneity in health & disease
hopefully PR is merged soon but it’s encouraging to see other users excited about it :)
reference != rest is still a WIP tho..

presenting a gpu-accelerated version of the wilcoxon rank-sum test for scanpy / rapids-singlecell’s rank_genes_groups tomorrow.
excited (and nervous) to show my work in a purely computational space for the first time! :)

promote [good] research. this was a nice, quick read but has some great points that i’m going to keep in mind as i work on establishing myself in the field and to you all..

Promoting (your) research
“I am a scientist focused on conducting research, not on promoting it.” This thinking strongly resonated with me when I was a PhD student. If it resonates with you, read on to learn why…

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...
I’m an award-winning mathematician. Trump just cut my funding.
The “Mozart of Math” tried to stay out of politics. Then it came for his research.

shoutout to my hpc for enabling me to work on 1M+ cell datasets, but still, an hour to embed the umap.. time to start learning gpu integrations in the scanpy workflow
