Research Summary

Alison Motsinger-Reif, Ph.D., is Chief of and a principal investigator in the Biostatistics and Computational Biology Branch. Overall, her group focuses on the development and application of modern statistical approaches for understanding the etiology of common, complex diseases. As the field of human genetics increasingly accepts a complex model of phenotypic development involving many genetic and environment factors, it is increasingly important to develop analytical strategies that incorporates this complexity. Data collected from different physiological compartments that represent biological flux across time and space, such as genetic, metabolomics, and environmental data, will need to be incorporated to gain a fuller understanding of the biological mechanism underlying complex phenotypes.

Her lab develops methods computational/statistical methods for such complex biological data. Her recent methods work includes the development of new approaches for boosted tree models while controlling false discovery rates, machine learning for predicting synergistic drug response, and the use of evolutionary algorithms for fitting nonlinear dose response modeling. While methods development is a key component of our research, real data applications are the driving factor. While her group works with a number of phenotypes, pharmacogenomic applications are a focus area.

More specifically, they use high throughput screens of anti-cancer drugs in lymphoblastoid cell lines to detect variants associated with differential response. Additionally, they leverage genome-wide genotyping of participants in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) to map a number of drug response and other clinically relevant traits. Finally, her group works with the Environmental Polymorphisms Registry (EPR). The EPR is an active North Carolina based cohort with exposure data from questionnaires and geospatial exposures, whole genome sequencing and electronic health record data. We are leveraging this powerful resource for exposome research, genetic mapping, and the discovery of gene-environment interactions. The lab also collaborates with several investigators to understand complex diseases and drug response with high throughput “omic” technologies. Example collaborations include projects in metabolomics, epigenomics, comparative medicine, and model organisms.

Relevance to NIEHS Mission

The development and application of methods for gene-gene and gene-environment interactions readily addresses the NIEHS mission to better understand aspects of individual susceptibility. Our methods development and applications directly serve the data science and big data mission. Additionally, environmental exposure are major contributors to the disease that we study — including Type 2 Diabetes and cancer. The methods that we develop and apply contribute to advancing environmental health science research.
