[TYPO3] possible to make page title dynamic?

[Bing Du]

Hello,

Can page title be dynamically changed just for display purpose?  Say, 
the title of the page is 'Research by Principal Investigator'. 
 Depending on which PI is clicked in the page, the page title should be 
changed to 'Research by Principal Investigator John Smith' in the very 
top border of browser. Again, I just want it for display purpose in web 
browser.  The actual page title should be still 'Research by Principal 
Investigator' in the page tree.  If that's possible, how should I do it?

Thanks in advance for any ideas.
