1/ Had a few folks ask where I’ve been in twitter discussions of COVID-19. Still here & doing what I can to promote & act on lowering inhalation dose of virus-laden aerosol particles. Continuing discussions w/ reporters & policymakers (when asked), but largely in the shadows.
2/ Been keeping up w/ twitter banter when I have breaks, some of which has been great & some enormously frustrating. My position as dean of @UCDavisCOE is demanding but exciting, and has been job 1 for the past 7 months. Hopeful to engage a bit more once the spring term ends.
3/ My passion for promoting the importance of lowering inhalation dose of virus-laden respiratory aerosol particles has not waned since the early days of the pandemic. If you've followed me for awhile you will be familiar with my early tweets.

1/ 3 hours in the late night & a seed tossed into the social media wind. Origin of the #CorsiRosenthalBox.

There were 2 motivations for the concept.

Motivation 1. Make effective air cleaning more accessible to those who cannot afford $300 HEPA air cleaners.
2/ Motivation 2. Help schools employ effective air cleaning at a cost that would not be prohibitive given financial constraints. In summer 2020 school districts seemed overwhelmed, confused, & vulnerable to purchasing shiny objects that might not actually be all that effective.
3/ Three criteria were considered for the device:
(1) Effective, removing a reasonable amount of virus-laden aerosol particles from indoor air.
(2) Inexpensive, much lower cost than HEPA air cleaners.
(3) Open source, not a “money maker” for anyone or any organization.

1/ Reducing respiratory aerosol particle concentrations in dorm rooms.

I have heard from parents who have children returning to dorms at universities across North America. The #corsirosenthalbox can help with these situations a lot! Really a lot, folks. read on.
2/ 8 hours unmasked while sleeping each night w/ 2 or 3/room should be a concern regarding infection, not to mention being poorly-masked while studying with others in the room.
3/ Increasing ventilation will help to reduce respiratory aerosol particle concentrations to the extent it is possible, but will be limited by system constraints or inoperable windows.
