  • My early work, performed in collaboration with my mentor Dr. Matthew Meyerson, included a meta-analysis of approximately 500 human lung adenocarcinoma expression arrays generated by the National Cancer Institute’s Director’s Challenge Program. We successfully reconciled discordant previous reports by demonstrating three reproducible molecular tumor subtypes of lung adenocarcinoma that are otherwise indistinguishable by routine clinical evaluation. The subtypes have statistically significant survival differences, independent of disease stager and are comprised of tumors with differing underlying rates of mutations in key lung cancer genes including KRAS and EGFR. Similar reports for squamous cell carcinoma of the lung are forthcoming, as are reports of clinically applicable diagnostic tests.

  • In collaboration with Kwok Wong, Ned Sharpless, Buddy Weissman, and Ben Major, I have documented the frequent mutation of the gene STK11/LKB1 in human lung cancers, including squamous cell carcinoma and mutations in KEAP1/NRF2 pathway.

  • Progress in two key areas of science has provided the foundation for the work in my group. First, the advent of personal computers along with associated progress in the field of statistical computing greatly accelerated the development of data-rich models of human disease behavior. Second, collaborative efforts across biomedical science have made available the building blocks of normal (i.e. The Human Genome Project) and aberrant genomes (i.e. The Cancer Genome Atlas, TCGA). To leverage the power of computers to assess alterations in the genome associated with cancer, a host of molecular technologies have become commercially available in recent years. The primary targets of these assays have been nucleic acids (DNA and RNA), although a limited number of protein assays are also included. The technologies allow labs such as ours to make broad and inclusive measurements in samples of alterations in gene expression (RNA), gene dosage (DNA amplification and deletions), gene structure (normal population variants, mutations, alternate splices, fusion genes, and epigenetic modifications), protein abundance and other events such as presence of a pathogen. Primary technologies used in my lab include array-based approaches (gene expression arrays, methylation profiling, SNP chips, CGH, miRNA arrays), sequencing (targeted and deep sequencing / “NextGen”), and immunohistochemistry (including tissue microarrays).
