The Department of Mathematics & Computer Science at Rutgers University - Newark is in Smith Hall (address: 101 Warren Street Newark, NJ 07103).

By train: There are two train stations in Newark: Newark Penn Station and Newark Broad Street Station. Either stations are at walking distance from the campus (see below). From New York, you can either take the NJ Transit from New York Penn Station or the PATH from World Trade Center. Either rides are about 20 minutes to Newark. Trains are frequent and you may find their schedules here for NJ Transit and here for PATH.

Walk from train station: From Newark Penn Station it takes approximately 17 minutes to walk (which is recommended) to the department, see map here. You can also take the Newark Light Rail Grove Street/Branch Brook Park line to Washington Street (the second stop). From Newark Broad Street Station, it will take you approximately 12 minutes to walk to the department along University Avenue, see map here.

By car: Here are the directions to the campus. For parking, you have two choices: Parking Deck 1 or 2. You should follow the online directions to Parking Deck 1 or Parking Deck 2. Make sure you keep the parking ticket you receive when you enter the parking lot, since you will need it to exit the parking lot.

Please feel free to contact me with any questions (also see contact below).

Teichmüller theory seminar

The Teichmüller theory seminar is an informal seminar organized by Jane Gilman, John Loftin, Brice Loustau and Anastasiia Tsvietkova. It is supported by the GEAR network and the talks are video recorded and available online. Please follow this link for the dedicated web page.
