The Ph.D. degree represents the highest level of academic preparation. With it, a student can expect to maintain technical competence and contributions throughout a professional career. It is usually the preferred degree for research and development in industry and government and for teaching. Doctoral studies emphasize independent research under the guidance of a research advisor in a field related to Chemical and Biological Engineering, culminating in the writing of a thesis document and its defense in a presentation to the department and the thesis committee. Financial support typically comes from fellowships, research assistantships, teaching assistantships, or a combination.<br><br>Research interests are focused on rationally designing or assembling nano-materials into advanced functional structures, characterizing these nanostructures, understanding their functioning mechanisms, and exploring applications ranging from fuel production, energy conversion, gas storage, to chemical separations. Our goal is to improve the energy efficiency in various fuel production processes and efficiently alleviate environmental pollution.
