My lab at SickKids in Toronto, Canada, studies brain development. We want to know how nerve cells wire to form complex neural circuits. Here for science, actions to make our world a peaceful, safe, and healthy place, laughs, and cycling.

NEW PREPRINT! An evo-devo look at how new cerebellar nuclei are made. Spoiler: it’s all driven by region-specific excitatory progenitors in the early rhombic lip; inhibitory neurons fill in later. If you care about brain evolution or cerebellar development, check it out: tinyurl.com/CNdevelopment

CIHR has launched a trial ballon that suggests shifting to one competition a year. This is the worst idea I have heard in a long time. The only benefit is making top-line success rates look better than they are. Keep it as is, do in-person reviews, and keep the pain in the open.

I’m very excited to announce that a part of my PhD thesis project is now a preprint! In this paper, we show how spontaneous activity prior to visual experience shapes neural circuits in the retina. (1/11)
