Research

My research is primarily in the areas of accommodation and presbyopia, and cornea and contact lenses.

Accommodation and Presbyopia
My graduate work was focused on developing better treatment options for presbyopia. My Masterís thesis demonstrated subjective and objective improvements with multifocal contact lenses compared to monovision correction. This work has been widely cited in both the scientific and lay press and has helped to change the standard of care and lead to wider adoption of multifocal contact lenses. My PhD work explored accommodative and biometic changes in presbyopia. Understanding how the lens and ciliary muscle change with age is critical to the development of better intraocular lens implants for the treatment of presbyopia.

Cornea and Contact Lenses
Since completing a Cornea and Contact Lens Fellowship, I have been engaged in collaborative research to understand risk factors associated with contact lens complications. As co-chair of the CLAY study group, we have explored risks unique to the pediatric population and have collaborated with the Centers for Disease Control to understand patient knowledge and risk-taking propensity toward contact lens wear. Over 41 million adults and unknown numbers of children wear contact lenses in the United States. Current research is exploring ways to utilize contact lenses to slow the progression of myopia, and diagnose and manage other diseases like diabetes and glaucoma. It is critical to understand contact lens related risk factors in order to support the development of these and other treatment options for children and adults.
