RESEARCH INTERESTS

Dr. Pendergrass is a Genetic Bioinformatician focusing on high-throughput data analysis and data-mining projects for uncovering the genetic architecture of complex traits. The data for these projects have come from a range of sources, where genotypic data has been coupled with the following: de-identified electronic health record data, population survey based data, clinical study data, and pharmacological study data. She has an interest in incorporating environmental exposure data in analyses of disease susceptibility, and analyses across ancestry. She has extensive experience developing novel methodologies and performing high-throughput analyses for discovery, such as those for Phenome-Wide Association Studies (PheWAS), an approach investigating the association between genetic variation and wide range of phenotypic variables.  She also has expertise in the development of unique software tools for data analysis, with software designed to enable researchers to access and analyze data in new ways. In addition, she has developed several unique software tools for data visualization: PhenoGram, PhenoGram-Genie, Synthesis-View, and PheWAS-View. Through her PhD she has expertise in gene-expression analyses and bioinformatics, with projects leveraging the complexity of gene-expression data for biomarker and biological discovery for the disease Systemic Sclerosis. Her masters work in Biomedical Engineering, and undergraduate degree in Physics, have provided her with additional technical and analytical expertise for complex data-driven projects.
