:
We don’t need a hashtag or a day to celebrate our resilience — we need policy changes that will allow us to thrive ❤️🔥
I'm giving my lab members a leave of absence next week so that they may use the time to vote & process the consequences of the election, as needed. Fellow academia decision-makers, I encourage you to cancel meetings, hit pause on emails, & consider how to best support your team.
The Rajan lab website now hosts a Comics page to share our
#SciComm
efforts! With the help of talented artists &
