The group has a Twitter account under the handle @RosenGroupPU. This is a shared account and can be used by various members of the group. All posts on the @RosenGroupPU account should be kept broadly professional in context. That doesn't mean they can't be silly or fun (in fact, I encourage it)! Simply remember that you're representing the group, so don't post anything you wouldn't say or share in the hallways.
I also have a personal Twitter account at @Andrew_S_Rosen. I will post a combination of science and random things on there. Feel free to engage... or don't, it's up to you. You can also connect with me on LinkedIn if you'd like.
I will occasionally post tutorials on my YouTube account, also under the handle @Andrew_S_Rosen.
