Point one: You claim to be his assistant. No proof to that claim has been provided. Over the internet, everyone can claim to be anyone. Wikipedia had a fair share of vandals claiming to be someone important/their relative/employee/etc.
Point two: You also hide behind a pseudonym. Yours, however, implies an assertion of authority on subject matter. I am inclined to suspect violation of WP:IU.
Point three: The article contains no references for the present content, but you have none for the modifications introduced in your edits either. Please refer to WP:V and WP:OR.
Point four: Emailing him would serve no purpose, as contents of that communication will not be verifiable for other Wikipedians. If you or Dr. Pinsky have access to the university's server or can contact a person who does, please publish the list of neccesary factual corrections there. That should satisfy the requirements of WP:V and at the same time be sufficient proof as to your identity as his assistant.
