Academic Qualifications:

Post-Doctoral Associate:
In the Bioprocess engineering area, particularly Biorefinery project in optimizing the process of making bio-ethanol out of the renewable materials such as wood in SUNY ESF. The work involves research in hemicellulose (sugars) extraction during hot and mild acid extraction from wood as well as other biomass. To quantify of the residual xylan, xylooligomers, xylose, and degradation product (furfural) obtained in the hydrolysis 1H-NMR spectroscopic analyses and Gas chromatography. Also involved in fermentation to make various bio products and membrane filtration separation research for better separation of the product of fermentable.

Ph D (Paper and Bioprocess Engineering), Dec 2005 GPA: 3.64/4.00, State University of New York, College of Environmental Science and Forestry, Syracuse, NY.
Dissertation: “Application of the Continuous Wavelet Transform for Analysis of Formation and Streaks in Fibrous Web Structures.”
MS. (Paper and Bioprocess Engineering), May 2001, State University of New York, College of Environmental Science and Forestry, Syracuse, NY.

B Tech. Engineering with Hons., May 1995 Indian Institute of Technology, Kharagpur, India.

Focus of graduate research:

Ph D research:
Paper formation- characterizing paper formation which affects every property of paper relative to and important for its use using wavelet transforms. Usual workday involved modeling of paper and fibrous structure, generating mathematically and capturing experimentally paper grammage matrix using β-radiographic images, analyze the same applying image and signal processing. This was contemporaneously pursued with experiments as literature review was conducted on a routine basis particularly with emphasis in paper formation. Results were presented to 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.

Work Experience:

Nov 2007-current:

Post Doctoral associate, SUNY-ESF

May-October 2007
Material Engineer

In CME associates - a consulting and inspection firm operating out of 5 branches in

NY state worked as a material Engineer. (I inspected soil shallow and deep foundation systems. I interpreted soil boring also. On a regular basis I prepared daily data logs as required by the jobs, daily progress report, maintained non-comformation deficiency and deviation list as I managed projects, I practiced OSHA regulations to plan for safety before excavation job, as geotechnical inspector responsibility, I evaluated safety and enforced structural design/drawing plans.

Aug 2006-May 2007
Visiting Assistant Professor-

Teaching Paper Properties, Coating and Converting (theory and lab in each case) and

Differential equation to undergraduate and Graduate students at SUNY-ESF. The Paper Properties course is all about the effect of papermaking composing materials, pulping and papermaking processes on the structural, mechanical moisture transport as well as optical properties of paper. I spent a lot of time in the laboratory as this course also covers laboratory session that teaches techniques to evaluate concepts taught in class.

January 2006-July2006
Solvay paperboard, Solvay-NY

Process engineering trainee-

Gathered mill experience working in process engineering under the process engineer

and the chief engineer’s supervision and conducting engineering experiments and calculations. Helped troubleshoot with stock preparation and environmental issues in the mill, as needed, participated in team meetings and provided input on objectives and methods of mill trials (including mill trials conducted to improve the wet end chemistry), conducted part of the experiment/study during mill trials. For example sampled stock slurry at the mill at different points, processes stock to develop fiber properties, making handsheets and testing them in labs at SUNY-ESF, in Auto line and manually, assessing fiber quality and estimate the value of fiber procurement source. Also wrote trial reports from the results. The focus was optimization of papermaking at the mill achieved by defining the fiber properties and following through its development under treatment. . In this work experience the other highlight was to be part of a machine rebuild and start up after the rebuild aimed at increasing the speed in the machine by working on the parameters to efficiently have desired flow rates through the screens, fractionators, Uclones and Xclones, disk thickeners etc stock prep units.

Summer 2003:
Solvay paperboard,

Testing engineering intern

I worked at the Solvay paperboard in their corporate paper testing laboratory.

The focus was conducting mill trials and writing production quality report evaluating the ongoing issues of structural failures of their board because of issues called flimsy board, pin adhesion and. In this work was exposed to the extensive use of chemical additives which often alleviated, minimized the issues at Solvay Paperboard mill.

August 1995-August 1997:

Design Engineer in a large private consultin firm in Dhaka Bangladesh named

Development Design consultants ltd. Where I worked on design and analysis of various civil engineering structures.
