What Are the Wing-Like Extensions on this Plane?

What is this?

I got this picture from the net. This plane participated in SAE Aero. Wanted to know what the two wing-like extensions from the wingfence were.
I was thinking they could be wingtips and serve in reducing drag and still direct flow as if there was an entire wing in their place. But roll control would be tough.

Wing Grid! You will find much more about it if you search the web.
