OverviewAI-generated summary
Robert R. Delongchamp's research group at the University of Arkansas for Medical Sciences focuses on public health and the analysis of genetic and environmental factors influencing health outcomes. He has served as Principal Investigator on a $206,229 grant from the NIH/National Institute for Occupational Safety and Health for a case-cohort study investigating cancers in excess among poultry workers.
His scholarly work includes publications on topics such as the reproducibility of microarray data, the mouse lymphoma thymidine kinase gene mutation assay, cancer mortality in atomic bomb survivors, N-acetyltransferase genotype and phenotype distribution, the CYP3A4*1B variant and breast cancer risk, persistent subclinical inflammation in atomic bomb survivors, and correlations between blood levels of S-adenosylmethionine, S-adenosylhomocysteine, and homocysteine with diet. Delongchamp's expertise is reflected in his h-index of 30, with over 130 publications and 2,845 citations. He collaborates with researchers at the University of Arkansas for Medical Sciences, including Leanna Delhey and Christina Joshua.
