The following is a list of Board research topics. These research topics will remain active until the Board either (1) elevates the topic to an active project or (2) decides to stop research on the topic in favor of committing resources towards more pressing issues. Each research topic page contains an objective and a history section—with the most recent information first. Staff contact information is also provided for interested persons to request additional information. Research topics are identified as priorities but not active on the Board’s technical agenda.
