Based on interviews with 172 academic scientists from 70 research universities in the USA, UK, Canada, Australia and elsewhere, this report presents highly detailed information about how they felt about the online and in-person scientific conference experience during the pandemic, and how they feel conferences should be held in the near future, and after the pandemic.  The study helps its readers answer questions such as: how many conferences have academic scientists attended during the pandemic and how many do they plan to attend currently and in the near future? How safe do they feel attending conferences in person? What percentage have they attended in person vs virtually?  What have they liked most and least about the online conference experience?  What would they like to see carried over to the post pandemic period? How might online and other technologies be best exploited by conference organizers in the near future?
