Professor of Chemistry	Rebecca Y. Lai B.S. California State University, Los Angeles Ph.D. University of Texas at Austin Postdoctoral Training at University of California, Santa Barbara	Our research program focuses on both fundamental and applied aspects of biosensor research. The main objective of our research is the design and fabrication of folding- and dynamics-based electrochemical biosensors. We aim at developing portable real-time biosensors for environmental monitoring and point-of-care diagnostics. Our sensing strategy is to link target-induced change in the conformation and/or flexibility of the biorecognition elements (e.g., peptides, nucleic acids) to a robust, electrochemical signaling mechanism. These sensors are reagentless, reusable, and insensitive to non-specific interactions of contaminants, enabling them to be employed directly in realistically complex media such as blood, urine, soil extracts, and a wide range of food matrices. We also develop hybrid analytical techniques, including electrochemical-surface plasmon resonance spectroscopy, electrochemical-surface-enhanced Raman spectroscopy, and fluorescence microscopy-scanning electrochemical microscopy, for characterization of this class of biosensors.
