Get some bright blinkers front and rear if she's going to be going home at night.
The place is near chinatown I think. That place is traffic city. Some side streets are empty but they're relatively narrow, tell her not to be afraid to take the lane if necessary, watch out for car doors, especially during busy hours.
And watch out for cab drivers, I was hit by one recently. Definitely get a helmet, saved my life more than once.
Also, try to secure as many parts as possible and make the bike look as old as possible. Chinatown is not the safest place in the world for a bike, especially after dark. See if she can take it inside the institute or otherwise, get her to buy a good kryptonite chain or u-lock and leave it in a secure location on the spot so she doesn't have to haul it home everyday.
