Welcome to the H. T. Soh Lab


    The Soh Laboratory Group at University of California, Santa Barbara works to develop novel materials and devices to improve the condition of human health. Our laboratory consists of researchers from many disciplines, including Physics, Chemistry, and diverse areas of engineering such as Materials, Mechanical, Chemical, and Electrical Engineering. Currently, our research focuses on two main themes: Directed Evolution of Materials and Integrated Biosensors. These two technologies hold the promise for early detection and personalized treatment for many diseases including Alzheimer’s, cancer, and diabetes.
