Research Interest

Understanding the interplay of multiple genetic and epigenetic factors in the human genome that can inform the risk for developing diseases e.g. cancers: Use of integrated ‘omics’ approach to analyze high throughput genomic data (including next generation sequencing) to understand genomic, epigenomic and non-genetic factors in disease pathways among populations of variable ethnic/genetic backgrounds. These approaches are currently being applied on breast and lung cancers in the populations of rural communities in Arkansas.

Current Research Projects

  • Screening for mutations in non-small cell lung cancer-specific candidate genes in the population of Arkansas (Seeds of Science; Mohammed Orloff, PI)
  •  Preliminary studies: applying a systematic cross-platform genomic integration to understand lung-associated diseases
  • Applying integrated omics (including analysis of next generation sequencing data) to map genes and pathways associated with Barrett esophagus and esophageal adenocarcinoma
