Biography

My work applies a multidisciplinary approach drawing on biochemical reactions, enzyme catalysis, microbial and bioprocess engineering principles for beneficial conversion of various agriculture materials and fermentation solutions to overcome major challenges in the industry. This research addresses the characterization and development of pretreatment approaches for enzymatic digestion of various biomass, lignocellulosic material, energy crop and other waste feedstock and microbial fermentation applied to transformation of agricultural commodities to biofuels, bioproducts, and biochemical. Prior to joining the Laboratory of Renewable Resources Engineering (LORRE, https://www.purdue.edu/lorre/) at Purdue University, I worked as a researcher in NongShim R&BD center, which is one of the global companies in Asia country (http://eng.nongshim.com/main/index) for 3 years. As a researcher, I participated in the development, testing, and patenting of processed food products. My main duties included that (i) process design and simulation of bioreactor (scaled up at 3000 L bio-reactors for soybean fermentation), (ii)  development of microalgae culture methods for producing functional oils, (iii) production of biologically active oils from fermented agricultural crops, (iv) control the oxidative stability of products (noodles, snacks, processed foods), (v) development of the removed carcinogenic compound (3-monochloropropane-1,2-diol) palm oil via enzymatic biocatalysts and refining process, and (vi) synthesize capsaicin analogue which has 1000 times milder (spice) taste. At Hood, I participate and contribute to developing technologies using coffee waste and hemp materials highlighting a new concept of microbial fermentation that does not require any cooking, mechanical, physical or chemical pretreatment methods nor the additional supplement of nutrients for ethanol, hydrogen and other biochemical production. This research aims not only to transform agro-residues into high value chemicals produced with partner academic and commercial labs but also helps to train students at the undergraduate level in research at Hood College.
