    The mission of the Elisseeff Lab is to engineer technologies to repair lost tissues. We aim to bridge academic research and technology discovery to treat patients and address clinically relevant challenges related to tissue engineering. To accomplish this goal we are developing and enabling materials, studying biomaterial structure-function relationships and investigating mechanisms of tissue development to practically rebuild tissues. The general approach of tissue engineering is to place cells on a biomaterial scaffold that is designed to provide the appropriate signals to promote tissue development and ultimately restore normal tissue function in vivo. Understanding mechanisms of cellular interactions (both cell-cell and cell-material) and tissue development on scaffolds is critical to advancement of the field, particularly in applications employing stem cells. Translation of technologies to tissue-specific sites and diseased environments is key to better design, understanding, and... ultimately efficacy of tissue repair strategies. We desire to translate clinically practical strategies, in the form of biomaterials/medical devices, to guide and enhance the body's natural capacity for repair. To accomplish the interdisciplinary challenge of regenerative medicine research, we maintain a synergistic balance of basic and applied/translational research. view more

  • James Knierim Laboratory

    James Knierim, Ph.D.
    Neuroscience

    Research in the James Knierim Laboratory attempts to understand the flow of information through the hippocampal formation and the computations performed by the various subfields of the hippocampus and its inputs from the entorhinal cortex. To address these issues, we use multi-electrode arrays to record the extracellular action potentials from scores of well-isolated hippocampal neurons in freely moving rats.

    These neurons, or "place cells," are selectively active when the rat occupies restricted locations in its environment and help to form a cognitive map of the environment. The animal uses this map to navigate efficiently in its environment and to learn and remember important locations. These cells are thought to play a major role in the formation of episodic (autobiographical) memories. Place cells thus constitute a tremendous opportunity to investigate the mechanisms by which the brain transforms sensory input into an internal, cognitive representation of the world and then use...s this representation as the framework that organizes and stores memories of past events. view more
