Graduate Student, Interdisciplinary Materials Science
Caldwell Research Group
I was inspired to pursue research in nanophotonics after taking Introduction to Spectroscopic Methods with my advisor, Dr. Joshua Caldwell. Learning how light鈥搈atter interactions allow us to probe materials, manipulate light, and develop technologies for sensing, communications, energy, and medicine completely changed my perspective. Seeing the breadth of possibilities convinced me that this was the field I wanted to build my career in, and I joined Dr. Caldwell’s research group shortly afterward.
My research focuses on designing nanophotonic structures that tailor light-matter interactions to selectively emit infrared light at the molecular absorption bands of a target gas, enhancing sensitivity and selectivity. I first used this approach for greenhouse gas detection, and I am now applying it toward noninvasive acetone detection for metabolic monitoring in patients with diabetes. After completing my Ph.D., I hope to continue developing optical technologies in industry or at a national laboratory.
VINSE has fostered an environment where researchers can see how interconnected their work is, including scientific foundations and problem-solving approaches, while offering diverse perspectives. Conversations with colleagues often give me new insights, and the welcoming, collaborative community has greatly shaped my research and personal growth.
Outside the lab, I enjoy spending time outdoors, whether I鈥檓 running, hiking to waterfalls, or exploring new places with friends and family. Growing up in Wisconsin gave me a lasting appreciation for lakes, so I鈥檓 always looking for a good waterfront. I also enjoy cooking and hosting friends and family, especially when I have a new recipe to share.
