Research Statement

Using Translational Research for the Development of Materials with Applications in Health Care and Sustainability

The focus of my research has been primarily in polymer materials used in both health care and sustainability applications.  I have a number of current research projects that are specifically aimed at hydrogels and their uses in optical drug delivery, stimuli-responsive materials in the design of self-monitoring irrigation systems, phase change materials used for thermal management systems, and super absorbent polymers that will degrade under environmental conditions for use by women in developing countries for personal hygiene. 

Creating chemical sensors from stimuli-responsive hydrogels was the focus of my dissertation work.  I used hydrogels with tertiary amine groups as the signal recognition component of the hydrogels.  The amine groups became protonated as the pH decreased, causing an electrostatic repulsion, and therefore a mechanical swelling.  The swelling pressure exerted by the hydrogel was measured with a piezoresistive pressure sensor.  One of the facets of this project was to optimize both the response time and swelling response. 

In addition, I currently have an active research project making polymers imprinted with a glaucoma drug.  These polymers are being explored as a potential drug delivery device that would deliver the drug directly to the ocular surface.  The project is in its infancy, but we have already obtained results with UV-Vis, showing that the drug is released from the polymer.  Progress is being made to determine the reversibility of binding as well as the extraction coefficient and the time for drug release.
