Roll all the way and, don't run, when the turrets are shooting at you.

Stay on the right side by the door and wait for the target closest to you to come
up. Roll behind it and wait until the gun has shot all of the target away; it only
shoots enough bullets to do that. Then, the target in the middle will come up.
Quickly roll again behind that one, and wait. Next, run and roll between the guns.
If you get hurt, there is a medpack on the wall. Run and do a jump kick to the
scientist. The guns will have destroyed themselves and you will be fine.
