This case is from a publicly available case study. Case studies tend to feature successful outcomes and may not reflect the full range of petition results.

Proposed Endeavor

The petitioner proposes to use fractional calculus and time scales to advance the study of approximations and investigate solutions to fractional differential equation models. This work aims to produce numerical solutions to models concerning infectious diseases, population growth, dispersal, and biological systems.

Framework Evaluation

3 of 3 criteria met
1 Substantial Merit and National Importance Met

The research improves the understanding of fractional differential equations critical to science, engineering, and the U.S. economy.

2 Well-positioned to Advance the Endeavor Met

The petitioner is well-positioned due to a record of 26 published articles and a citation record indicating reliance by other experts.

3 Waiver of Job Offer and Labor Certification Met

On balance, it was found beneficial to the United States to waive the standard requirements due to the nature of the mathematical modeling contributions.

Why This Petition Was Approved

The petition was approved based on the petitioner's 26 peer-reviewed journal articles (19 first-authored) and 96 citations, demonstrating significant impact. Additionally, the petitioner completed 40 peer reviews for authoritative journals and submitted six expert recommendation letters satisfying the Dhanasar prongs.
