Quantitative Scientific Solutions

Quantitative Scientific Solutions, commonly known as QS-2, was a boutique scientific, engineering, and advanced analytics consulting firm based in Arlington, Virginia. The company provided technical consulting, data analytics, systems engineering, testing and evaluation, and digital solutions to federal and commercial clients. Its capabilities spanned biotechnology, artificial intelligence, aviation, autonomous systems, and program management, but it did not operate as a therapeutic biotech or drug-development company. In April 2022, QS-2 joined EY-Parthenon, and the business appears to have been absorbed into EY's consulting organization rather than continuing as an independent operating company. As a result, it is best characterized as an acquired consulting firm with some life-science-adjacent capabilities rather than a healthcare product company.
