Research

Currently, I work on understanding the dynamics of tear films. Three key areas of my current focus are:

1. Interaction of Contact Lens with Epithelial cells –  The human cornea has a tendency to become irritated after periods of extended contact lens wear, resulting in discomfort and the need to frequently replace the contact lens.  It is thought that this may be caused in part by corneal cell adhesion to the contact lens. Using a custom in-house built cell rheometer, we hope to understand the effect of soft hydrogel contact lens on live epithelial cells. Results from this study will be presented at the upcoming ARVO conference in 2013 as well as the annual European Rheology conference in Leuven (AERC, 2013).

2. Dewetting dynamics of contact lens - Using a custom Langmuir trough, we are investigating the dewetting dynamics of fluid layers on hydrogel surfaces. This work will also be presented at the 2013 ARVO conference in Seattle.

 

3. Influence of lipid layers on droplets – The effect of lipid layers on interfaces is a problem involving various complex phenomenon. In this project, we study the effect of monolayers on sessile droplets. A manuscript is under progress.
