美国弗吉尼亚科技大学招聘生物能源方向博士后
1-2 postdoc positions in Biofuels R&D at Virginia Tech (USA)
Protein Engineering and Synthetic Biology
Our research integrates engineering design principle with biology and chemistry to solve the most challenging tasks in biofuels (cellulosic ethanol and hydrogen) production from non-food biomass. The main challenges that we are addressing are (1) how to release sugars from biomass, and (2) how to convert sugar to desired fuels?
Applicants will conduct the biofuels-related projects: (1) increasing cellulase activity on insoluble cellulosic substrate by applying directed evolution (we have several unique selection and high-throughput selection methods under development), (2) clone, characterize and express hyperthermostable enzymes for in vitro synthetic biology projects (a beginning stage of low-cost, high-yield, greenest hydrogen production from sugars, highlighted by the UK Royal Socity), and (3) increase key enzyme performance by using directed evolution or rational design techniques.
Our lab is building the world-class leadership in biofuels field by several breakthroughs (see my representative papers).
Educational Requirement: Ph.D. degree in Applied Biology, Molecular Biology, Microbiology, Biochemistry, Biochemical Engineering, or relevant majors. The postdoc candidate must have good publications as the first author. The relevant experience in protein engineering and protein characterization is preferred. The applicant should be self-driven, be willing to learn new knowledge and technologies, have strong problem-solving ability, and have good communication skills.
