Incoming Assistant Professor at CUAnschutz in Jan 2025 | Post doctoral fellow in the Shih lab at SCRI | Brain perivascular cells in small vessel disease
I am thrilled to share that the Bonney Lab will be opening its doors come January @CUAnschutz in the department of Anesthesiology! We will study perivascular pathology in cerebral small vessel disease using in vivo and ultrastructural imaging approaches.
Super excited to share our work: inhibiting Ca2 channels in Alzheimer’s disease model mice relaxes pericytes, improves cerebral blood flow and reduces immune cell stalling and hypoxia. nature.com/articles/s41593-0… 1/6
Ever wonder if small injuries to capillaries have lasting consequences? Our work exploring this question is now out! None of this would have been possible without the help of some brilliant minds - @NielsonCara @sosamariaj @OrlaBonBon@AndyShih_Labpnas.org/doi/10.1073/pnas.23…
We found that the vasomotor dynamics of upstream transition vessels is greatly attenuated however mural cell calcium signaling is maintained. Consequently, chronic constriction of the upstream transition vessels reduced blood flow to uninjured secondary off-shoot capillaries.
These studies demonstrate how small injuries to capillaries could alter blood flow in a broader sense within each microvascular network unit. There are sooo many more details to these studies so if you are curious I hope you take a dive deeper into our paper.

I have soooo many people to thank for all their guidance and support along the way, most of all my mentors @AndyShih_Lab and @SiegenthalerLab. And my amazing colleagues @sosamariaj and @NielsonCara for going on crazy adventures with me in the Shih Lab.
I am recruiting graduate students, postdocs, and research staff. The future of vascular physiology research is bright, and I'm excited to fill the space with amazing people & discoveries.
What makes cerebral white matter more vulnerable with age? In this mouse study, we show that large and rare venules are bottlenecks for blood flow in the white matter. Deep branches of these venules are constricted with age, leading to reduced blood flow.

This mini review was a fun one for @sosamariaj and I where we dove into the mysteries of brain perivascular fibroblasts! Thank you to @AndyShih_Lab for guidance on this one! Please enjoy 😊!

Happy to share the latest preprint from the @AndyShih_Lab! Here we learned how focal capillary injury in the brain may broadly affect blood flow. These adventures wouldn’t have been possible without @NielsonCara and @sosamariaj by my side! biorxiv.org/content/10.1101/…
Happy to share that my K99 is getting funded! I will be diving deeper into the mysteries of perivascular fibroblasts in the brain🕵🏻♀️! None of this would be possible without the support from my amazing mentors throughout this journey @AndyShih_Lab @SiegenthalerLab!
The MICrONS 3D EM strikes again! This time we were curious about endothelial features that may dictate vessel size. Check it out if you’re curious too!
Shout out to @sheridan_sarge for quite the feat during her rotation!
Brain capillary diameters are fine-tuned to optimize blood flow and nutrient delivery. #Pericytes can regulate capillary size, but is that the whole story? Here, we use #MICrONS volume EM data to show that endothelial structure is also involved.
