A couple of years between the last two pictures. One was taken only a couple of days after @xinruilimemily1.bsky.social started her postdoc and the last as Emily completes her postdoctoral work in our lab @uvmlarnermed.bsky.social!

All the best with your future endeavors!

People are worried. I thought only PIs are disturbed but I realized yesterday that lab members are worried about the uncertainty as it comes to jobs fully supported by NIH grants.

A friendly reminder: please reassure your students and trainees during these uncertain times.

We will persevere!

Outstanding and inspiring study!

Norepinephrine (NE)-mediated slow vasomotion drives glymphatic clearance during sleep

- NE release drives slow vasomotion in NREM sleep

- NE oscillations trigger opposing changes in blood/CSF volumes & predicts glymphatic clearance

Paper is out today @biophysj.bsky.social!

Amyloid beta Aβ1-40 activates Piezo1 channels in 🧠 capillary endothelial cells

Congratulations 🎉 to @xinruilimemily1.bsky.social and Luc Willemse. We enjoyed having Luc in the lab as a visiting student. So proud of Emily and Luc!

Looking forward to visiting David Geffen School of Medicine at #UCLA tomorrow. If you are in town and interested in learning about our research on #Piezo1 channels in the brain vasculature and how they affect neurovascular coupling and brain blood flow, I hope this will be of interest.
