What I Do I am a researcher in the field of biophotonics, which is the intersection of light and biology. The work I do is primarily chemistry and materials development. I explore the relationships between the surface chemistry, structure, and physical properties of advanced materials that can be used in optics, electronics, and environmental applications. Specifically, I work with a unique type of sensor device that can be used for medical diagnostics (for instance, to test if there are certain disease markers in a sample). These devices have high sensitivity (even down to the single molecule level!), but they are not specific. That is, they are not able to accurately detect one type of biological entity versus another. So, I am investigating and developing new ways to make these sensors detect only specific biological components, while at the same time, making sure that they remain highly sensitive.
