## Scientific Review Panel

The scientific activities of the Pacific Institute for the Mathematical Sciences are reviewed by an arm's-length Scientific Review Panel (SRP) of experts from various fields of the mathematical sciences. The SRP meets once a year to make recommendations to the Board on the selection of upcoming scientific activities.
