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 and optoelectronic 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 Electrochemistry as well as Department of Electrical and Computer Engineering at University of Texas at Austin. During the period of his postdoc and research associate, he completed many outstanding multidisciplinary projects. The area of his expertise stretches from material design to new related disciplines involving material characterization and diverse applications, such as solar fuels, organic and inorganic photovoltaic cells, wastewater treatment and food waste management.
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 organic and inorganic 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 electricity generation, solar fuel production, wastewater treatment as well as food waste management. The investigations between material phenomena rely heavily on concepts of energy and environmental engineering, consisting of photophysics, electrochemistry, photoelectrochemistry by utilizing scanning photoelectrochemical microscopy (SECM) imaging, ultrafast transient absorption (TA), time-resolved photoluminescence spectra (TRPL) and so forth.
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.
