The following are Research Outputs from all resources supported since 2010 that have been reported to Research Computing staff. To list your publications, presentations, grants, awards, students graduated, etc, please contact Ryan Bradley.

In early 2021, the computational cluster Hawk that was enabled by NSF support (Award #2019035) was put into production. A significant portion of the scholarly works produced since Hawk was deployed in 2021 were wholly or partly made possible by this computational resource, which is made available as a no-cost discovery platform for Lehigh University researchers, educators, and students.
