IndoorChem 2021

The 2021 Chemistry of Indoor Environments Meeting will take place as a series of virtual events during January – May, 2021. Meetings will be gathered via Zoom, with a cap of 500 participants per session. Sessions 1-4 will be 1h20min long and present three speakers on a common topic, followed by a live panel Q&A. The last session (May 25th), will include a plenary talk by Prof. Charlie Weschler on Zoom, followed by a 2-hour poster and virtual networking session on Gather Town.

On social media, let’s use #IndoorChem2021


Virtual sessions will be open, free of charge, to the general public but pre-registration is required. You will receive occasional emails from us with reminders about each session and other meeting-related communication.

Sharing policy

Talks will not be recorded for sharing on the internet. In the interest of encouraging a free exchange of preliminary findings while enabling some sharing on social media, we are establishing the following policy for this meeting:

  • No sound or video recording of presentations is allowed.
  • No photos of data slides or posters are allowed without permission from the author.

This means that photos of title/introduction/broad conclusion slides are allowed and could be shared on social media. If speakers are uncomfortable with photos of any form, they can add a note on their slides or poster requesting “No photos / no tweets” and all meeting attendees are expected to respect this request.

Conduct policy

Unprofessional conduct, including disruptive behavior or harassment, will not be tolerated in these events. Attendees found to post inappropriate comments in the chat windows or who attempt to disrupt the meeting will be removed from the events.
