Areas of Expertise and Interest
My primary research interest is focused on synthesis of semiconducting nanowires, nanosprings, and nanoparticles by using CVD-based techniques. The length of those nanostructures extends to centimeter range and diameter around lower tens of nanometer. Characterization of their various properties makes those nanomaterials promising applications in versatile sensing and solar energy systems. I am also interested in studying electronic structure, magnetic and optical properties of solid bulk, thin film, and low dimensional nanomaterials by using a standard software package (wien2k). It is based on a standard computational technique of density functional theory. In addition, I am interested in educational and pedagogical research in STEM disciplines. Old-fashioned teacher-center activities in classroom are gradually out-of-date. Recently I am working on intro-level course redesign to switch classroom activities from traditional lecturing to instructor active teaching and student active learning manner. The goals of such changes are to improve student learning and success, and retention in STEM disciplines.
