Arxiv/biorxiv updates, talk additions

[Lawreros]

Added:

• talk at rockefeller, columbia
• co-chair on Biology and Bioinformatics at SciPy 2020
• Black in AI Mentor
• Update arxiv/biorxiv links (biorxiv doesn't have a url that automatically goes to the latest version, so I replaced them with their corresponding doi url links which always go to the latest version)
• changed ndmg to m2g
