Harvard university plays host to gaius chibueze

I think there may be some confusion here!

Harvard University is a prestigious institution of higher learning located in Cambridge, Massachusetts, USA. While it's possible that a person named Gaius Chibueze may have visited or studied at Harvard University, I couldn't find any information that suggests the university "plays host" to him.

Could you please provide more context or clarify what you mean by "plays host" in this context? Are you referring to a specific event, lecture, or program that Gaius Chibueze was involved in at Harvard University?
