Skills:

Skills learned from my PhD project: Design syngas fermentation experiment using microbial catalysts (such as Clostridium) to investigate the effects of impurities (such as benzene, hydrogen sulfide, ammonia, etc.) in syngas from a gasifier on cell growth, enzyme activity and ethanol production. Good in designing and building bioreactors (1-3 Liters) from scratch for specific experiments. Knowledge of varying operating parameters (such as pH, Redox levels, two stages of bioreactor run) to optimize ethanol production. Perform mathematical modeling of gas-liquid transfer and enzymatic kinetics (One paper submitted on this topic). Five year's experience in the operation of steam- sterilized continuous stirred tank bioreactor with all the controls. Expert in using gas/liquid chromatography to analyze headspace gas compositions and ethanol concentrations. In-depth knowledge of GC-mass spectrometry (MS). Trace amount of benzene concentration in media can be detected and measured using MS. Good at using statistical methods to design experiments such as factorial or fractional factorial design, response surface methodology. Demonstrated knowledge of using software such as Aspen plus II to model trace amounts of impurities in producer gas from a gasifier. Establishment of a database for syngas compositions for varied feed-stocks and operating conditions for a gasifier. Five peer-reviewed papers as first ivethor have been or will be published from this project.
