No, currently NIAID is not participating in any funding opportunities that use the Outstanding Investigator Award (R35) activity code.
On our Opportunities & Announcements page, you can use the search bar to pull up a list of active funding opportunities under a particular activity code, e.g., “K99/R00”. More intuitive, though, is to browse our opportunities list using the Grant Type filters on the left navigation bar, e.g., “Research Career Development (K)”.
