If you have access to the SMF data on your system, you can find out from that -- but it is not necessarily an easy process. AFAIK, there is no simple way to determine while the CICS region is running who is doing what transaction.
Your best bet is to contact your site support group and ask them for assistance. They may already have this data available or know the best way to get it.

Third-Party monitors, such as TMONCICS, can give you (amongst other data), the userid, after the transaction has finished.
You can list all the given active tasks with TMON and expand on one and you might be able to catch one before it terminates. But normally, transaction lifetime in many shops is usually not greater than two seconds, so you have to be quick.
Why do you need to know information about a particular user?
You can get this information from your Security group.
