Research Focus

My research focuses on how the body reacts to implantable non-rigid biomaterials. We use non-rigid biomaterials for a broad range of surgeries, such as breast reconstruction, hernia repair, and ocular lens replacement. While these materials are all safe, when adverse tissue reactions such as chronic inflammation or fibrosis occur at the tissue-implant interface, the implanted device becomes non-functional and patients suffer significant morbidity. To better understand why these adverse reactions happen, my lab studies the impact of various surgical and biomaterial factors on the tissue reaction at the implant interface. We are interested in using this information to develop surgical, molecular, and biomaterial solutions to improve the biocompatibility of non-rigid implants and their associated surgical outcomes.
