What will I be doing?

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 goal of this project is to implement a novel method that simulates diminished lung surfactant function and assesses respiratory health effects of particles through biophysical (cell-free) and biochemical (in vitro) endpoints.  The proposal influence operational impact by improving Airmen respiratory resiliency and improve mission performance by identifying and mitigating hazardous exposure. 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?

You will develop and advance your professional and academic career through doctoral and/or post-doctoral training.  This exciting opportunity not only provides advanced research training during and beyond the doctoral degree but prepares you to follow scientific careers at the AFRL. Along the way, you will engage in activities and research in several areas. These include, but are not limited to, conducting research on the following objectives: 

  • 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 diminished 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.

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
