 Applied Research -Services Provided for the Benefit of Industry and General Public

For the last 28 years (1994-Present), I have been serving as the coordinator of industry and public service activities of MSE (School of Materials Science and Engineering). As a part of this activity, I have interacted extensively with all types of fiber product manufacturers around the country and solved hundreds of their problems of applied nature in the areas of product design, product evaluation, raw material selection, process optimization, technical trouble shooting, legal defense of products and processes, etc. A significant part of my funding support came from the private industry.

Expertise in Statistics and Advanced Data Analysis

Extensive exposure to Minitab and SAS statistical packages and EXCEL data analysis tools; Expertise in using experimental design, data visualization, data programming and charting tools; Analysis of univariate and multivariate data sets for business and research purposes using statistical tools such as multiple regression, cluster analysis, factor analysis, PCA, etc.; Knowledge of Tableau, Python, SQL and R; Critical thinking skills; Preparation and presentation of effective data analysis reports to decision makers.

Expert Testimony Services

Served as a field expert in more than 48 litigations (court cases) involving fiber/polymer/textile products and their manufacturing technologies. Presented expert testimony in federal, state, and county courts in eight different states. Helped to solve four murder cases that involved, fiber, rope and garment evidence. Also helped to solve three rape accusations based on fiber transfer evidence.
