Effects of Inhaled Chemical & Particle Mixtures on Lung Surfactants Internship
As an ORISE participant, you will join a community of scientists and researchers in an effort to gain knowledge in areas related to the Air Force Research Laboratory's (AFRL) mission.
The overarching aim of this research is to improve rapid assessment of aerosol exposures to military personnel using relevant substances. In this proposed research, aerosols will be generated using nebulization and then passed through the surfactometer chamber where lung surfactant (LS) films are positioned immediately below the aerosol intake valves, thus simulating in vivo surfactant surface area changes during breathing. One of the advantages of the system is its ability to increase temperature to simulate heat stress, decrease oxygen content to simulate hypoxia, or reduce the temperature to simulate arctic conditions.
In addition, the project aims to produce and characterize degradation products from aerosolized chemicals, particles, and biohazards in an effort to identify specific constituents that trigger lung toxicities.
Why should I apply?
Under the guidance of a mentor, you will gain hands-on experience to complement your education and support your academic and professional goals. Along the way, you will engage in activities and research in several areas. These include, but are not limited to:
- Learning to design, construct, and build a user-friendly device, termed surfactometer, to use in the research laboratory as a means to screen various Air Force operationally relevant aerosols for indicators of diminish lung function.
- Collecting data (such as droplet shape, size, and other physical features of the lung surfactant fluid as well as inflammation, irritation, and allergic reactions within cells/tissues) that links to respiratory health endpoints.
- Assessing the interactions between lung surfactant films and a panel of aerosolized ‘benchmark chemicals/particles’ relevant to Air Force operational settings.
- Measuring the impact of diminished surfactant function on tissue surface structure and molecular profiles using a multi-lung cell/tissue model.
- Designing and building a functional device that can house and test the biological effects of aerosols on lung fluids, cells, and tissues in a sterile environment. Biophysical changes in lung fluids and biomolecular changes in cells/tissues will inform potential adverse respiratory health effects of Airmen in operational environments.
- Building and validating a computational/statistical simulation model capable of distinguishing (and predicting) respiratory health effects via diminished lung surfactant function due to aerosol exposure and assist development of exposure guidelines.
Where will I be located?
Wright State University in Dayton, Ohio
What is the anticipated start date?
Exact start dates will be determined at the time of selection and in coordination with the selected candidate. Applications are reviewed on an ongoing basis and internships will be filled as qualified candidates are identified.
What is the appointment length?
An ORISE appointment period can be a short-term (less than 2 weeks), summer (10-12 weeks), or yearlong appointment. Appointments may be extended depending on funding availability, project assignment, program rules, and availability of the participant.
What are the benefits?
You will receive a stipend to be determined by AFRL. Stipends are typically based on a participant’s academic standing, discipline, experience, and research facility location. Other benefits may include the following:
- Health Insurance Supplement (Participants are eligible to purchase health insurance through ORISE)
- Relocation Allowance
- Training and Travel Allowance

This program, administered by Oak Ridge Associated Universities (ORAU) through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and DoD. Participants do not enter into an employee/employer relationship with ORISE, ORAU, DoD or any other office or agency. Instead, you will be affiliated with ORISE for the administration of the appointment through the ORISE appointment letter and Terms of Appointment. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.
