CNS Response to Implanted Materials
Our primary research focus is in understanding and manipulating the response of nervous tissues to implanted devices in order to improve the biocompatibility of several classes of indwelling devices including stimulating and recording electrodes, bridging devices, cell transplantation vehicles, drug delivery devices and catheters. Using histological techniques and cell based approaches, our group studies the foreign body response, especially the interactions of activated macrophages and the affect of persistent inflammation on adjacent nervous tissue function. In pursuit of our goal, we employ several novel approaches including, novel biomaterials and bioreactors for engineering cell derived ECM for use in bridging devices, specialized devices for cell transplantation, novel surface coatings for biomaterials, and have developed new tools to study soluble factor delivery in brain tissue.
