This is an AAO appeal decision — a case denied once and appealed. It shows how the framework is applied; it is not the filing population.
The Petitioner, a biomedical engineering researcher pursuing a PhD, proposed to continue postdoctoral research on parvalbumin-expressing neural activities during sleep and wakefulness to understand links between cerebrospinal fluid clearance disruption and neurodegeneration.

Notable
AAO reversed the Director on all three Dhanasar prongs, sustaining the appeal in full; case turned on STEM-related policy factors (Policy Manual F.5(D)(2)) supporting both prong 2 and prong 3.

What this case teaches
Analyst reading of the decision text.
AAO found detailed expert letters establishing both prospective field-wide impact (prong 1) and STEM/NIH-funded credentials plus collaborator interest (prongs 2-3) sufficient, reversing Director's narrower national-importance reading.
Pair a mechanistically specific research plan with expert letters that explicitly tie the work's prospective impact to broader disease/field advancement, not just personal skill descriptions.
