The main area of my research is studying the mechanisms of reversible photodegradation in certain dyes. The idea is, it may be possible to condition existing materials using light, radiation, and thermal cycling to make them better. Our work is based on a serendipitous discovery that certain materials self-heal after photodegradation, and that they become more robust in the process.Currently I am trying to understand the fundamental principles underlying self healing properties of dye called Disperse Orange 11 doped in PMMA polymer.

The photo-mechanical effect is applied to certain materials in which we measure induced strain through the depth of the material as a function of time using a Fabry-Perot interferometer while the material is illuminated using a laser source. This research involves two processes known as the thermal mechanical effect and photo-reorientation and is the basis for the evolution of future “smart”materials.

The transition moments between excited states play an important role at determine the intrinsic hyperpolarizabilities. It can be studied by measuring two photon absorption cross sections of molecules. A better understanding of the transition moments will help us to design molecules with larger intrinsic hyperpolarizabilities

I am building optical tweezers to manipulate metal nanoparticles, in the hope of utilizing it to design and assemble materials with high nonlinear optical response from bottom-up, and also to verify previous theoretical calculation results.

I am using quantum approximation methods to find the elasticity of DNA’s, atoms and molecules. For this purpose, we use the similarity between polarizabilities and different orders of elasticity.

The research I am doing currently is quantifying the self healing of a doped polymer over time by looking at burn marks due to exposure to intense laser radiation.  I utilize photo analysis software to measure the width and "depth" of the burns as a function of time to look at how the polymer heals.

I am a Junior at Washington State University, majoring in Physics.  My main focus working with Dr. Kuzyk focuses on self-healing compounds.  Certain materials have been found to have the ability to heal themselves over time, seemingly regaining all their initial properties.  Image analysis provides a new set of information regarding these identically regenerated properties.  By studying before-and-after conditions of a “destroyed” sample, fundamental information about these compounds is expected to be determined.
