Directions to CLIC
First, find Columbia University. CLIC is accessible through the Fairchild Building (Biology). It is at the north end of campus. Just before you reach the Mudd building (coming from the south side of campus), you will see an overhang, covered in red brick tiles. Enter the glas door and take the short hallway right of the elevators. You will find a second, swipe-card-protectd door. Once you pass that door, turn right and then the first door on your left leads you into the lab.
The lab has the official room number CS486, but is not accessible through the Computer Science Department by the general public.
