Pulmonary Infection and Immunity
- This is joint work with Erik Bozcko and Erin Murphy, Department of Biomedical Sciences in
the College of Medicine at Ohio University.
We are seeking to develop a new non-invasive monitoring technique, invented by Bozcko, to mitigate
ventilator associated pneumonia. We are also seeking to use the monitoring technique as a tool
to non-invasively study the human immune system in the lungs. We are currently funded by
the college Research and Scholarly Affairs Committee
