The successful candidate will serve as Project Lead in cell-based and animal use research studies on environmental and occupational exposures to identify health effects before health and operational performance is compromised in the warfighter. ​

Are you ready for unique and exciting work?

Research efforts will require study design, medical and scientific authoring and editing of research proposals, animal use (IACUC) protocols, technical and scientific reports, responses to grants and funding calls; scientific management, coordination of technical review meetings and the preparation and presentation of point papers, technical reports, and other briefings resulting from these meetings, preparation and support of technical summaries and publications resulting from research activities; presentation of research findings at scientific meetings / professional conferences; writing, reviewing, editing, and submitting peer-reviewed articles and technical reports.

Your Main Objectives:

• Work with a diverse team of scientists, including toxicologists, engineers, neuroscientists, chemists, psychologists, animal behaviorists and biologists, to accomplish the mission of understanding the health effects of operating in military settings.

• Design and conduct scientific research on the inhalation toxicological effects of exposure to chemicals/mixtures; these may be in combination with extreme environmental hazards or stressors, to include temperature, humidity, altitude, vibrations, and noise, and/or physical demand.

• Utilize animal models to evaluate the short- and long-term health and performance effects of acute and chronic exposure to chemicals, mixtures, environmental hazards and stressors.

• Provide scientific expertise in the field of inhalation toxicology regarding all organ systems, including pulmonary, neurological/cognitive and developmental and reproductive effects.

• Identify, devise, propose and execute military relevant studies and collect data from animal subjects (primarily rodent)

• Develop appropriate exposure systems, including analytical techniques for identifying toxicants and/or aerosols.

• Contribute substantially to the design and building toxicant generation and other exposure systems.

• Perform risk assessments based on collected toxicological data.

• Assist other investigators in the design and execution of research protocols on inhalation toxicology and environmental exposure issues of interest to the Navy.

• Operate and maintain standard and specialized laboratory equipment.

• Assist and educate entry level research assistant personnel in the understanding and performance of their duties.

• Collect pulmonary/respiratory data, or other appropriate endpoints, from animal subjects following exposure.

• Perform statistical analyses using SigmaPlot, Statistical Package for the Social Sciences (SPSS) or Statistical Analysis Software (SAS). Examples of the typical analyses required for successful performance include T-tests, Chi-Square, Analyses of Variance, Multivariate Analyses of Variance, analyses of covariance, multivariate analyses of covariance, correlations, linear regressions, multiple linear regressions, and power analyses.

• Use multiple computer software packages to create spreadsheets and perform statistical routines.

• Independently and proactively prepare mission-relevant proposal applications for toxicological, physiological, psychological, medical, and performance studies.

• Independently and plan, manage, oversee, and carry out research proactively ensuring that those assisting in project coordination are fully informed and able to perform proposed/funded research, meeting all project deadlines.

• Develop technical reports, presentations, and publications.

• Be willing and able to work nontraditional hours (e.g., nights, weekends) as needed.

• Perform other duties as needed.
