Dr. Jordan-Sweet's research interests lie in the use of x-ray diffraction techniques to study materials that are used in microelectronics manufacturing; in particular, the properties of thin films and features during and after the processing conditions to which they are subjected. Techniques used include high-resolution XRD (strain, phase ID), XRR (roughness and layer composition), pole figures (texture), and in-situ, time-resolved XRD during rapid thermal annealing (phase transformations, barrier failure, grain growth, texture changes).

Professor of Chemistry Dr. Lee carries out x-ray and neutron scattering measurements on lung surfactant, a complex mixture of lipids and proteins that assists the breathing process to obtain structural information on lipid/lipid, lipid/protein and lipid/polymer organizations of these 2D lipid systems. Her work is designed to better understand the molecular causes behind the proper functioning of the lung and to help explain how specific chemical or physical alterations in lung surfactant might lead to Respiratory Distress Syndrome. Lee also studies beta amyloid, a plaque-forming substance implicated in the pathology of Alzheimer’s disease.

Other projects include targeting selectivity of antimicrobial peptides, the use of polymers as membrane sealants, and the interactions between lipids and cholesterol in the cell membrane.
