Laboratory of Translational Genomics

Understanding the contribution of genetic variation to cancer etiology and outcomes

The Laboratory of Translational Genomics (LTG) conducts studies on germline and somatic genetics of cancer, including analyses of regions of the human genome conclusively identified in cancer-specific genome-wide association studies (GWAS) and family-based studies.

Research Mission

The mission of the LTG is to understand the contribution of germline and somatic genetic variation to cancer etiology and outcomes and to elucidate underlying molecular mechanisms of these associations. Our primary goals are to:

  • Detect cancer susceptibility alleles across multiple cancer types and ancestries
  • Fine-map susceptibility alleles using sequencing, genotyping and imputation based on data from public databases
  • Prioritize candidate variants for follow-up studies through bioinformatics analyses
  • Decipher the biological mechanisms underlying susceptibility alleles through laboratory investigation
  • Establish genomic resources representing diverse ancestries and cancer sites to facilitate cancer genomics research
  • Integrate cutting-edge, high-throughput functional genomics approaches in genetic/epidemiologic studies

Research Laboratories

Each LTG investigator heads a laboratory focused on specific research.

Tour of the Laboratory of Translational Genomics (LTG)

Join Francine Baker, M.S., predoctoral fellow, and Ludmilla Prokunina-Olsson, Ph.D., LTG Director, and Senior investigator, on a tour of the laboratory.


LTG accepts fellowship applications on an ongoing basis. Meet the current LTG fellows and learn about research training opportunities in LTG.
