Research

Biomimetic Cilia, University of North Carolina, Chapel Hill, NC, 2004 - 2007

Designed novel ferrofluid/poly(dimethyl siloxane) composite material and ferrofluid-hydrogel materials.  Developed fabrication processes for producing arrays of actuable microscale biomimetic cilia using these materials.  Demonstrated fluid flow driven by actuated arrays.  This work is featured in the "Zoom In" exhibit at the Morehead planetarium at UNC-CH.

 

Motor/Generator Automation, Auburn University Fusion Lab, Auburn, AL, Summer 2002

Acquired proficiency in new programming languages. Interfaced ten motor/generator units with a logic controller to power an experiment in nuclear fusion. Achieved complete automation of motor/generator run cycle and enabled remote user intervention and control through local area network.

 

Ultrasonic Scanning System, Rhodes College, Memphis, TN, 2002

 Responsible for designing protocol for operation of a three-dimensional ultrasonic scanning system to be used for backscatter, broadband ultrasonic attenuation, and speed of sound measurements.

 

Dual Energy Contrast Enhanced X-ray, University of Tennessee, Biomedical Engin., Memphis, TN, Summer 2001

 Operated and maintained a small linear accelerator used for x-ray production. Designed optimal x-ray spectra for new imaging technique and implemented a procedure for investigating the efficiency of the technique in medical applications. Culminated in a live animal study.

 

Medical-Grade Polyethylene Investigation, Rhodes College, Memphis, TN, Summer 2000

 Used transmission electron microscopy (TEM) and atomic force microscopy (AFM) to examine structural characteristics of ultra high molecular weight polyethylene.

Current Projects

I am primarily interested in the application of nanoscale techniques to explore questions of biological interest.  My current work is in the area of biomimetics, where I am making life-sized artificial cilia in order to study fluid-structure interactions similar to those within biological systems.  This work has applications in research on diseases of ciliary dysfunction such as cystic fibrosis, as well as applications in fluid physics, materials science, and bioengineering.  Specific interests include:

 

 •       Nanotechnology / Biotechnology

 •       Magnetics

 •       Polymers / Colloids / Composite materials

 •       Fluid Physics
