Dr. Sam H. Y. Hsu obtained his PhD degree under supervision of Prof. Kirk S. SCHANZE at University of Florida with focusing on photophysical behaviors of functional metallopolymer materials for solar energy applications. After that, he received the two-year postdoctoral and research associate’s appointments respectively with Prof. Allen J. BARD and Prof. Edward T. YU in Center for Electrocemistry and Department of Electrical and Computer Engineering at University of Texas at Austin. During thhe period of his postdoc and research associate, he completed many outstanding multidisciplinary projects. The area of his expertise stretches from multistep synthesis of organic-inorganic semiconductors to new related disciplines involving diverse areas of applications and material characterization, including solar fuels, organic and inorganic photovoltaic cells, ultrafast laser spectroscopy, and scanning photoelectrochemical microscopy imaging.
Dr. Sam H. Y. Hsu’s research interests involve the material design, synthesis, processing, imaging, spectroscopy and solar energy application, aiming to explore fundamental properties and interactions of hybrid perovskite semiconductors and functional metallopolymer materials for developing efficient solar energy conversion processes. He has keen interests in photoinduced charge transfer processes, interfacial electron transfer, electrochemical hydrogen generation, and photoredox reactions for photovoltaics and solar fuel production. The investigations between material phenomena rely heavily on concepts and techniques of material and physical engineering, consisting of photophysics, electrochemistry, photoelectrochemistry, scanning photoelectrochemical microscopy imaging, ultrafast transient absorption and time-resolved photoluminescence spectra.
There are several openings for research assistants, graduate students and postdoctoral fellows. Effective writing and oral communication skills in English are essential. Postdoctoral fellow candidates must have a Ph.D degree in Materials Science, Chemistry, Synthesis, or a related field. Candidates for graduate studentships positions must have a Bachelor's degree in Physics, Chemistry, Materials Science, or a related field. Successful candidates will conduct research in synthesis, photophysics, electrochemistry and photoelectrochemistry for solar energy applications. Interested individuals are encouraged to submit their CV and research statement to Dr. Sam Hsu, firstname.lastname@example.org. Review of applications will begin immediately and will continue until the positions are filled. The next intake of graduate student will be for the academic year starting from September 2017.
City University of Hong Kong is an equal opportunity employer and we are committed to the principle of diversity. We encourage applications from all qualified candidates, especially applicants who will enhance the diversity of our staff.
