APL’s Response to COVID-19 New Laboratory Operations and Visitor Guidance

APL Campus

The Johns Hopkins University
Applied Physics Laboratory

We solve complex research, engineering, and analytical problems that present critical challenges to our nation. APL—the nation’s largest university affiliated research center—provides U.S. government agencies with deep expertise in specialized fields to support national priorities and technology development programs. We also serve as independent trusted technical agents to the government, providing continuity for highly complex, multigenerational technology development systems.

Our Purpose

Our Purpose

Our purpose is to make critical contributions to critical challenges. At APL, we feel it is our responsibility to try to solve these national challenges with the full measure of our dedication and expertise.

Our Core

Our Values

The Lab’s core values are unquestionable integrity, trusted service to the nation, world-class expertise, and game-changing impact—all in an environment that is collaborative, fulfilling (and even fun!).

Our Future

Our Goal

APL’s purpose and core values guide our future, and it is no less than to create defining innovations that ensure our nation’s preeminence in the 21st century.

Scientists at Johns Hopkins APL are working on a system to monitor physical fatigue in near-real time. Such a capability could prevent countless musculoskeletal injuries, and fits into a larger portfolio of work at the Laboratory focused on predictive health and human performance modeling.

Accelerating Materials Research with AI Keeps Johns Hopkins APL Researchers Ahead of ‘Impossible’ Challenges

Researching novel materials — and in particular, characterizing their properties to ensure they’ll function as intended — is time consuming, resource intensive and expensive. APL is leveraging its expertise in artificial intelligence/machine learning, modeling and simulation, and materials science, as well as its additive manufacturing capabilities, to accelerate the characterization and analysis pipeline.

Johnson Named Johns Hopkins APL Chief of Staff

As APL’s new chief of staff, Erik Johnson tackles a variety of tasks that loom large over the future of the Laboratory. He shares how his mentors and experiences have prepared him to guide the Executive Council’s strategic decision-making agenda — and much more.

REACTOR Prototype Brings XR Collaboration Capabilities

Engineers at Johns Hopkins APL are addressing the challenges of collaborating across wide physical distances by taking advantage of new technologies, designing and implementing the Mixed Reality Collaboration Environment framework, or REACTOR. This unique system allows subject-matter experts and analysts to interact and collaborate globally, with no externally hosted servers and with the capability to customize the approach to the user’s needs.

NASA Extends Johns Hopkins APL-Led Solar and Space Physics Research Center

After two years of progress in developing a beyond state-of-the-art computer model, the APL-hubbed Center for Geospace Storms will continue expanding for an additional five years, NASA recently announced, citing the center’s significant potential to transform the fields of space weather and space physics.
