2002 Research Project: Investigation of Lung Surfactant Collapse Mechanisms Using AFM.
This summer I worked on a research project investigating lung surfactant
collapse mechanisms using AFM (Atomic Force Microscopy). Lung surfactant
is a surface active molecule we have in our lungs to help with the absorption
of oxygen in the lungs. Premature infants have not developed their own lung
surfactant and can have respiratory distress syndrome. The overall goal of
the research group is to develop an artificial lung surfactant system to be
injected into premature babies to aid them in breathing. The overall goal is
divided into many separate research projects. The goal of the research I did
over the summer was to determine how specific monolayers collapse. l used an
LB trough to collapse different monolayer samples and I looked at the collapsed
structures under AFM

2003 Curriculum Project: Hands-on Lab Activities
During my RET 1 experience I spent 6 weeks in a chemical engineering lab working
with lung surfactant. This time in the lab was spent doing hands-on experiments
where I was manipulating equipment and samples. Previously in my earth science
classes we have not had “hands-on” lab experiences. My curriculum module was to
develop hands-on lab experiences that could be incorporated into the standards-based
earth science curriculum. These labs will be spread out over the entire year.
I will be using a lab activity every week or two. These labs have been designed
so that my students will gain experience manipulating lab equipment, gathering data,
analyzing their data, and writing about their results.
