How to find out the thread count of each user on linux Tikanga

There are 6 EBS applications running on a Exalogic server.

I want to find out the threads running on the server involved by each application user.

Thread count and the details of each thread.

I found ps -Leo user|sort|uniq -c|sort -n

[appluatdmz ~]$ ps -Leo user|sort|uniq -c|sort -n

   1 dbus

   1 ntp

   1 rpc

   1 rpcuser

   1 smmsp

   1 USER

   1 xfs

   2 avahi

   4 haldaemon

   13 appluatdmz

   84 oracle

  101 oragent

  110 orarom

  301 applpreproddmz

  308 root

  326 oradisc

  1030 appldev1

  2381 appldev2

But how to find the details of each process?
