Associate Professor at UMKC. I study sleep, memory and decision-making using the Drosophila model. Also, Pink Floyd is the best band in the history of music, period.

🚨 Postdoc openings!
We’re looking for postdocs excited about sleep, synapses & cellular neurophysiology (fly or mouse).
Yes, we also have mouse projects!

So I found this guy at the game today. What a great unplanned meeting.

I’m pleased to report that I am no longer an Assistant Professor. It took a long time but just heard I was tenured. Thank you to lab members, colleagues, funding providers, reviewers, editors, and anonymous letter writers for all the support through the years.

Coming back to the lab after 4 weeks away and finding that AC failed over the weekend in one of my rooms….significant loss of stocks. Great way to restart.

Why do some neurons say “sleep” while others shout “stay awake!” — inside the same brain?
In fruit flies, researchers just mapped the molecular chaos behind this nightly tug-of-war. And it’s wilder than we thought.

Thanks for coming. Great to see you again
Many thanks to @sdissel.bsky.social for the opportunity to speak @umkc.bsky.social! Love catching up with my sleep fam. 😴

We wrote an insight on a recently published paper @elife.bsky.social from groups at Janelia and California State University. The paper describes novel cell-specific tools to manipulate central complex neurons in Drosophila.

Neuronal Signaling: Cell-specific tools for understanding behavior
Novel tools that allow neuron-specific investigations of the structure controlling sleep regulation in fruit flies reveal the extent of neuronal heterogeneity.

What a week… I am laughing about it cause there is nothing else to do. I don’t believe in coincidences m, and also it is worth repeating again: 23E10-GAL4 is not a dFB-specific driver, so any reported sleep effects seen with that tool MAY or MAY NOT be dFB related. Time will tell….

Authors of a paper in review « your preprint is cool, it’s the most extensive dFB investigation that I have seen. Can I have your flies? » Same author once their paper is accepted coming to the same conclusion as our study. « No need to cite that work ». Make it make sense.

So I’m pleased to see that some people who were really adamant that the dFB does not modulate sleep have changed their minds. However I don’t understand why on earth they did not cite our work which demonstrates this and is now accepted at PLOS Biology.
