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, an environmental engineer with a Ph.D. in civil/environmental engineering, proposed to develop statistical models and life-cycle assessment methods for solid waste and wastewater treatment, including forecasting harmful algae blooms and improving water quality analysis in the United States.

Notable
The Director had not analyzed the first Dhanasar prong at all in the denial; the AAO independently evaluated and found it satisfied, then reversed the Director's finding on prongs two and three as well, sustaining the appeal in full.

What this case teaches
Analyst reading of the decision text.
AAO found petitioner's peer-reviewed publications, independent citations, and expert letters showed her research on solid-waste/membrane technology and algae-bloom forecasting had genuine cross-institutional influence and public-health/environmental relevance, satisfying all three Dhanasar prongs.
Pair a specific research agenda with independent, uninvolved experts' letters showing others building on the work, plus government agency data establishing societal stakes.
