I spend 3+ hours a week, since 2013, exclusively on ankle pt exercises so I can *walk* every day. (Removing the pt time immediately after surgery)
We all have unique things but it makes our weeks unequal.

DEI is under attack, but the stakes are higher than many realize. Universities *must stand firm* in defending it. I lay out why in my latest piece for Nature.

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.
