Interfacial chemistry lies at the center of all research projects in the Gawalt research group. The main focus of our laboratory is in the area of biomaterials. Biomaterials are synthetic materials placed in the body to replace or reinforce bones and tissues. The interaction of these materials with the body is integral to their long-term success. In one project we attempt to reduce implant infections by focusing on the interaction between metal implants, such as stainless steel, and surrounding tissue and bacteria. Our approach is to reduce the non-specific adsorption of scar tissue and bacteria through chemical modification via monolayers and polymers. Another project focuses on developing a new bone defect replacement material. Students on these projects gain experience in a wide variety of skills including synthesis, spectroscopy, surface analysis and tissue culture. Additionally, we also study the effect of interfacial environments on heterogeneous organometallic catalysts.  Research projects are discussed in detail on our group website.
