To further clarify, Eric is not in any way affiliated with @HarvardEpi. He is a visiting scientist, a temporary, usually unpaid (not sure in this case) position in the Dept of Nutrition which carries no endorsement by the university. He has self-promoted shamelessly during COVID https://twitter.com/DrEricDing/status/1250215792043610113

Those of us who research infectious disease outbreaks @HarvardChanSPH are embarrassed that for the moment he has the affiliation with our school and look forward to the time when he will not sully our institution with his mix of platitudes and alarmist nonsense

The distinction btw nutritional epi and infectious disease epi may seem like inside baseball. But having this person on as an epidemiologist is like having an ambassador to Russia on to comment on Saudi Arabia, on the grounds that she is an "Asia expert." True but not on point.
