Academic Qualifications:

Post-Doctoral Associate in SUNY biorefinery research institute:

I have been involved with wood based Biorefinery that can make bio-fuel and bio-product out of the lignocellulosic material.

Hydrothermal pretreatment of wood chips is well-known for hemicellulose (sugars) extraction where woodchips are catalyzed by the acetic acid produced in the treatment process. I have worked on quantifying the residual xylan, xylooligomers, xylose, and degradation product (furfural) obtained in the hydrolysis techniques were carried out using 1H-NMR spectroscopic analyses and Gas chromatography.
To make biofuel and product with sugar, fermentation of extracted sugars have been carried out to make ethanol and PHA. on a NYSERDA (New York State Energy Research and Development Authority) grant.
Following the fermentation I have worked on membrane filtration in biorefinery application. Applied cross-flow microfiltration (pore sizes 0.05, 0.1 and 0.2 micron) to separate the components of extract. Techniques used to characterize the filtrate and permenates were UV-Vis, Turbidity, zeta potential, Optical density, particle size analysis.
To make the biorefinery compatible with existing pulp and paper industry my efforts were in developing strength properties of paper from the extracted wood chips. I am Studying Polylactic Acid (PLA) on strength development of Biorefinery and regular kraft pulp of bleached and unbleached variety.
In order for biorefinery to be a platform chemical for renewable fuel and products,

I am involved in work to make wood strands from the extracted chips. The modification in wood chip by hydrothermal pretreatment calls for understanding the composition and properties of the woodchips for wood strands in a DOE grant.

I Have experience in proposal writing, compiling monthly reports in collaborative work with the industry.

Ph D (Paper Engineering), Dec 2005 GPA: 3.64/4.00, State University of New York, College of Environmental Science and Forestry, Syracuse, NY.

Focus of graduate research:

Ph D research:

Paper formation- characterizing paper formation which is linked to important properties such as strength, print quality, smoothness, coating ability. The project was collaborated with METSO who supplied us paper with various formation defects. Usual workday involved developing grammage matrix image using β-radiography, analyze the image in computer by image and signal processing. This was contemporaneously pursued with Lab scale experiments of flocculated sheets and simulation of paper and fibrous structure for analysis of a model system. Literature review was conducted on a routine basis particularly with emphasis in paper properties and paper formation. Results were presented before small and large audiences.

MS research:

Modeling of paper fibrous network- Mechanical model of paper structure to understand the underlying factors behind strength of paper. Additionally exploratory studies also conducted on fiber ultra-structure where tensile testing of individual fibers through special equipment assembly to fundamentally understand fiber strength.
