Uma T. Shankavaram, Ph.D.
Dr. Shankavaram manages the Radiation Oncology Branch’s Microarray Core Facility (MCF), which provides services and access to new technologies to investigators from NCI and other NIH institutes. The MCF offers special expertise in gene expression array hybridization, statistical analysis, genetics/genomics, and technical support.
- Gene Expression Arrays: gene chip processing of cDNA and Affymetrix arrays
- Boinformatics Analysis: consultation with scientists prior to experiments, analysis of high-throughput sequencing, gene expression, metabolomics, proteomics and other biological data, including functional and gene set enrichment analysis
- Application Development: develops custom applications to enhance research through web applications for data analysis, databases, visualization, and custom analysis tools
- Training: informal training to assist researchers in using computational tools

Biology is driven until recently by the study of individual biochemical compounds and genes. However, new technologies allow experimentalists to gather rapidly growing amounts of data at the scale of the entire cell, and a key challenge is now to integrate these data in order to progress towards a systems-level understanding of biological functions. In this framework, my research interests center around the field of cancer bioinformatics with special focus on radiation response on gene expression, pharmacogenomics and translational medicine. My other research interests are in the development of relational databases for biomedical projects, as well as the use of data mining and machine learning techniques for bioinformatic analyses. Following are the major topics my research projects: - Genomic data analysis and integration - Statistical pathway analysis - Target gene discovery - Bioinformatics tool development
