How do I approach him lol?

So there’s this guy, he’s a good looking guy and I see him around but I haven’t ever talked to him other than an “excuse me” and a “sorry” when we almost banged into each other.

I follow him on Instagram and he requested to follow back, he doesn’t follow half of his followers. I also am connected/following him on LinkedIn.

I want to get to know him more, he’s doing a PhD and I’m doing a masters, we’re both in the same department but he’s in microbiology and I’m biochem. We also share the same cold storage room, so I see him almost once a week.

Any tips on how to approach him and talk to him, possibly be friends too? Either through Instagram where we follow each other or in person without seeming too awkward?

Asking for some help 👉🏼👈🏼
