                                        Biographical Sketch:
                                        Dr. Chen received his Ph.D. from Auburn
                                        University, Alabama. His current research focuses
                                        on experimental characterization of Wide Band-
                                        gap Semiconductor Materials, especially 4H-SiC.
                                        One critical problem is the poor interface quality
                                        between SiC and SiO2, which significantly lowers
                                        the channel mobility of MOS devices on SiC. Dr.
    Research Fields:                    Chen’s goal is seeking effective approaches to
                                        increase the channel mobility.
