The Xie Group is located in the Mallinckrodt Building at 12 Oxford Street. Enter through the lower doors, down the steps to the right of the main entrance. Go through the set of double doors and turn left. The door to our offices is halfway down the hall on the left, marked “Xie Group, 027-029."

At night, weekends, and holidays the building will be locked, so you will need to call someone from the group to let you in (617.496.8654 for the main lab, or 617.496.9925 for Prof. Xie) or ask the security office to call for you.

By T—Directions from the Harvard Square stop on the Red Line

It’s about a five-minute walk from the train station to our offices.

1. There are two exits from this station. Exit via the turnstiles leading to Harvard Yard/Church Street. After the turnstiles, turn left and ascend via the exit labeled Harvard Yard (not the Church St. exit on the right).
2. Once above ground, go straight ~20-30 feet. Enter Harvard Yard through a gate on the right.
3. Facing forward, angle yourself 45 degrees to the left and follow the asphalt pathway.
4. Pass through another gate, exiting the Yard. You are now facing the Science Center. Continue walking in the general direction of that original 45-degree angle, keeping the Science Center on your left. You will see a large Victorian Gothic brick structure—Memorial Hall—on your right. Stay on the pathway running between the Science Center and Memorial Hall.
5. You will arrive at a street with a right-angle bend. This is actually the join of two streets. Oxford Street goes to the left, along the Science Center. Cross at this corner, and walk along Oxford Street.
6. You will see the Science Center on your left and the red-brick Lowell Lecture Hall on your right. 12 Oxford Street is the second building on your right. It is a brick building with columns. If you see an open lawn area on your right, you’ve gone just a bit too far.
