C-SOPS Webinar Series Presents

Powder Handling and Characterization for Design of Pharmaceutical Manufacturing Processes

Yifan Wang, Ph.D.

Wednesday October 12 2016 @ 1:30PM EST

While powder handling and processing is common in pharmaceutical manufacturing, multiple challenges, for example jamming of hoppers, sub-standard blending performance, weight variability of final products, and process scale-up failures, are encountered during production due to lack of fundamental understanding of powder behavior. Powder characterization techniques have a central role in both product and process development. By characterizing materials using a substantial number of flow property techniques, a material library has been established. Methodologies based on principal component analysis are provided to classify materials so that process performance of a new material can be predicted based on knowledge of exiting materials in the library. The material property knowledge is integrated with multivariate analysis and process analytical technology tools to enable predictive capabilities for process and product development. In a quality-by-design approach, information extracted from the material library has been used to develop data-driven models to predict process performance. A case study using material characterization methods and data analysis tools to predict powder flow in feeders will be discussed.

Yifan Wang, Ph.D.

Yifan Wang is currently an ORISE fellow at FDA. She received her Ph.D. in Chemical and Biochemical Engineering at Rutgers University in 2016.

She completed her Professional Certification (2011) in Chemical Technology from KTH/Royal Institute of Technology, Sweden and BS (2012) in Pharmaceutical Engineering from Dalian University of Technology, China. She was awarded the Rutgers Engineering Leeds Fellowship, the Evonik Fellowship, and the China National Scholarship.

She has been actively involved in research projects in the Catalyst Manufacturing Consortium, and Engineering Research Center for Structured Organic Particulate Systems. She serves as a student representative for the Regulatory Sciences Section of the American Association of Pharmaceutical Scientists. Her expertise is to develop experimental and statistical methodologies for material characterization and process development.
