Was hoping to share good news at a better time but realized it may not come for 4 years, so here it is! First paper from the lab. We show a transient L5 to L2/3 connection in developing cortex that drives activity-dependent maturation of upper-layer circuits.

This is the most relevant article to NIH and research cuts I’ve seen.

Imagine if this was today , how many people would be saying “Why are we studying Gila Monsters and their impact on diabetes ? That’s wasted money !”

Really proud to see my postdoc work out!!
