Location and Parking

All activities of DelMar Numerics 2018 took place on Brown Lab 101, on the main Green of UD's campus.

If you are driving to Newark, we recommend you to park in the Trabant Parking Garage. The cost for the full day is only $5. We will have a limited amount of validation tickets. If you want to have one reserved for you, send an advance email to

Brown Lab is building 51 on the campus map. Access to the Trabant Parking Structure (on the corner of S Main and W Main) is from a little side street at the beginning of W Main Street. Pick up a ticket when entering the parking. The validation ticket is used at the time of payment.
