THIBODAUX, La. (AP) - Nicholls State University will hold a conference Wednesday reviewing the effects of the BP PLC oil spill two years ago.

Keynote speaker is Donald Boesch, appointed by President Barack Obama to the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling.

Boesch is a professor of marine science at the University of Maryland.

Other speakers include Robert Dickey of the Food and Drug Administration, state health officer Jimmy Guidry and LSU environmental sciences professor Ed Overton.

The conference will be held in the student union building with registration beginning at 9:30 a.m. It is open to the public.

The spill, which began with the explosion of the rig Deepwater Horizon on April 20, 2010, led to the nation's worst offshore oil disaster.
