It depends which Congress.
If you mean the US Congress, then there is no single presiding officer. Each house of Congress has a different officer that serves that role.
The House of Representatives elects its own Speaker, who is currently John Boehner of Ohio. Vice President Joe Biden from Delaware is the President of the Senate. On a day to day basis, the Senate chooses a member to act as President Pro Tempore (president "for a time") in his place. Currently, Daniel Inouye of Hawaii is the President Pro Tem of the Senate.
In both cases though, the President Pro Tem and the Speaker of the House can appoint other members of their respective houses to preside over the chamber from time to time.
