Bioinformatics and Biostatistics

Director:  Weida Tong, Ph.D.

Dr. Tong is a gifted computational chemist with broad expertise that spans the entire spectrum of computational methods in molecular modeling and bioinformatics applied to systems biology, predictive toxicology, and knowledge management. He is internationally recognized for his leadership in the areas of computer modeling and bioinformatics, serves as a Science Advisory Board (SAB) member for the Netherlands Toxicogenomics Center, and as a SAB member for the EU Framework Project on CarcinoGenomics. Weida received his B.S. in Chemistry (1983) and his Ph.D. in Polymer Chemistry (1990) from Fudan University in China. Weida’s efforts and leadership qualities have made a significant impact within FDA and worldwide. He has supervised the FDA-led community-wide MicroArray Quality Control Consortium, analyzing technical performance and practical utility of emerging molecular technologies; and coordinated the development of the Liver Toxicity Knowledge Base to address public health concerns related to drug-induced liver injury. He played a major leadership role in the conception, design, and development of numerous computational tools in bioinformatics, chemoinformatics, computational toxicology, biostatistics, and systems biology. His work and creativity have public health impacts in predictive systems toxicology and risk assessment. His research (>160 publications) is cataloged in eminent peer-reviewed journals.
 

Mission

Division of Bioinformatics and Biostatistics develops integrated bioinformatics and biostatistics capability to address increasing needs in biomarker development, drug safety, drug repositioning, personalized medicine, and risk assessment. Its capability is directed towards integration with FDA business processes to ensure that NCTR linkages with FDA Product Centers are strengthened, and that the NCTR informatics capabilities continue to become more diverse, robust, and capable of meeting future and demanding needs of FDA.

The Division develops:

  • informatics capabilities and coordinates these capabilities within NCTR, across FDA Centers, and in the larger toxicology community
     
  • methods for the analysis and integration of omics datasets with classic in-life parameters
     
  • biometrical methods for all aspects of FDA’s mission, goals, and objectives
