Andrew Marley, MPH, PhD

Indiana University Richard M. Fairbanks School of Public Health

Dr. Marley is pursuing a career in cancer research, specifically focusing on the behavioral and nutritional factors that influence skin cancer risk and gene-environment interactions that modify this risk.

Dr. Marley’s research has resulted in the following findings: 

  • High total citrus consumption (>2 servings per day) was associated with a 63% increased risk of melanoma 
  • High consumption of oranges and orange juice (>1 serving per day) were the main drivers of the positive association for total citrus, and were independently associated with melanoma risk 
  • High citrus consumption was not associated with risk of non-melanoma skin cancer 
  • In a genome-wide analysis, there was evidence that the association between total citrus consumption and melanoma risk was modified by 7 SNPs linked to AFG3L1P on chromosome 16
