ARA, an employee-owned applied science company, is seeking a Physiological Modeler with a background in epidemiology, immunology, and/or virology. A successful candidate will work with an interdisciplinary team of scientists and mathematicians to develop high-fidelity models of human response to chemical and biological agent exposures.

The models will focus on host immune response, synergistic effects of multiple injuries/illnesses, and medical countermeasure action and efficacy. Models that are developed will transition to analytical platforms designed for a variety of uses, including risk assessment, training in virtual environments, and medical logistics. In addition to solving challenging problems of national importance, ARA provides mentorship, opportunities for rapid career growth, strong benefits, and flexibility to prioritize your work/life balance. We hope to hear from you!

In addition to model development, the position will require support for the verification and validation of models, report writing and technical presentation, and collaborating in interagency working groups. An ideal candidate would have a strong mathematical background and can show application to physiological processes in a manner that can speak to both technical audiences and lay audiences. A successful candidate will work with a small but focused interdisciplinary team comprised of mathematicians, computational biologists, physicists, and programmers. The ability to work with a team in a collaborative environment is highly desirable; either virtually or in person, depending on needs.

Our broad research portfolio includes the characterization of human health effects from CBRN and other hazards, retrospective and predictive risk assessments of hazardous agents, medical planning, and the development of scientific software. Most of our modeling and simulation work supports decision-makers across a spectrum of federal, state, and local agencies. ARA offers our staff members clearly defined technical and/or management growth tract opportunities that will allow you to help define the types of problems and projects that you like to work on. As you progress in your career at ARA, you will have the opportunity to follow your chosen track and progressively tackle more challenging tasks which will allow you to move into more senior positions with potential for your own projects, research, and customer relations.
