   October 17, 2025 @ Cornell Tech

NYC Privacy Day   

 

 

Hosted by DLI (Digital Life Initiative) and SETS (Security, Trust, and Safety Initiative), NYC Privacy Day 2025 is an informal setting to gather and connect researchers working on data privacy at different institutions in the greater New York City area. The schedule below is organized thematically, and the majority of time will be spent in collaborative group discussion. We have designed the agenda to generate conversation more than to showcase individual research projects, including discussion about works-in-progress, syntheses of existing studies, and/or provocations.

Getting to Cornell Tech's Bloomberg Center


Below is a list of multi-modal transportation possibilities for getting to the Bloomberg Center at Cornell Tech (2 West Loop Road).
 

F-Train to Roosevelt Island Station
 

  • Catching the F-Train to Roosevelt Island is certainly the quickest and most efficient way to venture to Cornell Tech.

  • Once you ascend to the street level, walk south under the bridge for 5-mins until you see the Bloomberg Center.

 
Cab/Lyft
 

  • Even though your ultimate destination will be 2 West Loop Road, when catching a cab or Lyft, we recommend you enter/use this address: 1 East Loop Rd, New York, NY 10044.

  • Given that vehicular access to Roosevelt Island is only from Queens, the journey can take up to 55-mins.

  • Once you arrive, walk to the Bloomberg Center. 

 
Whimsical Options
 

  • There is a fun cable car from NE Manhattan at 59th Street and 2nd Avenue over to the island (with access from the 4,5,6, and N, R, W lines). Only a metro card is needed. 

  • For novelty, a ferry service to Roosevelt Island is also available, accessible from Wall Street, Brooklyn Navy Yards, East 34th Street, Astoria, and East 90th Street.

 
Bloomberg Center Foyer Check-in

  • When arriving inside the Bloomberg Center foyer, kindly check-in at the security desk.

  • Once through the turnstiles, follow the signs to the workshop venue
