Kenilworth, New Jersey

The 100-acre Kenilworth site is our world headquarters and a main biologics research and development hub for our company. Kenilworth's R&D activities also include core chemistry and preclinical development (PCD) capabilities critical for advancing our discovery portfolio.

Our Kenilworth site is part of New Jersey's "Biopharmaceutical Life Sciences Cluster," a concentrated area of biotechnology, medical device, and pharmaceutical companies.

Kenilworth employees who live locally do so for many reasons: The proximity to New York City, nearby parks, open spaces, as well as accessibility to the 1-95 corridor. Northern New Jersey also offers some of the best public schools in the nation.

Employees have access to two on-site cafeterias and a credit union. Employees can take advantage of free shuttles to the Kenilworth campus from Newark Penn Station, Rahway Train Station and Roselle Park Station. Shuttle transportation between our sites is also available. For those who drive to work, our Kenilworth location is located directly off the Garden State Parkway.

MRL Locations - San Fran
South San Francisco, California

We are expanding our California discovery research footprint with a new cutting-edge research facility in the heart of South San Francisco’s biopharmaceutical community.

This new, nine-story, multi-disciplinary discovery research site will feature laboratories and office space to accommodate more than 300 scientists. When the site opens in Fall 2019, activities will span exploratory research through early clinical development. In the interim, our scientists are working at our nearby facility on Gateway Blvd., initially focused on cardiovascular, metabolic and renal disease research.

In 2019, our immunology, oncology and biologics groups currently based out of our Palo Alto, California research facility will transition to the new site. Our Bay Area research labs are integral to our world-class network of medicines and vaccine discovery and committed to turning breakthrough science into meaningful therapeutic options for patients.
